The term emulation originates in computer science, where it denotes mimicking the function program or computer hardware by having its low‐level functions simulated by another program. While a simulation mimics the outward results, emulation mimics the internal causal dynamics. The emulation is regarded as successful if the emulated system produces the same outward behavior and results as the original.
Whole brain emulation (also referred to as mind uploading or mind transfer) is the hypothetical process of scanning and mapping a biological brain in detail and copying its state into a computer system or another computational device. The computer would have to run a simulation model so faithful to the original that it would behave in essentially the same way as the original brain, or for all practical purposes, indistinguishably. The simulated mind is assumed to be part of a virtual reality simulated world, supported by a simplified body simulation model.
In analogy to a software emulator, a brain emulator is software (and possibly dedicated non‐brain hardware) that models the states and functional dynamics of a brain at a relatively fine‐grained level of detail.
The first attempt at a careful analysis of brain emulation was a technical report (Merkle, 1989b) predicting, “a complete analysis of the cellular connectivity of a structure as large as the human brain is only a few decades away”. The report reviewed automated…...

...The Brain The Five Major Structures of The Brain At the beginning of birth there are initially three swellings in the human brain. Once adulthood is reached the brain develops two new swellings. The forebrain and the hindbrain grow into two different swellings, this is how two more are added while becoming an adult. Once as an adult the brain consists of five structures that make up the fore, mid, and hindbrain from anterior to posterior. These five structures are the Telencephalon, the Diencephalon, the Mesencephalon (mid-brain), the Metencephalon, and the myelencephalon. Myelencecephalon The Myelencephalon is the posterior part of the brain, also known as the medulla. It is composed largely of tracts carrying signals between the brain and the rest of the body. An interesting part of the Myelencephalon is called the reticular formation. Reticular formation is a complex network of around 100 tiny nuclei that occupies the central core and also the brain stem from the posterior boundary of the Myelencephalon to the anterior boundary of the midbrain. This part of the brain even plays a role in arousal which is why it is sometimes referred to as reticular activating system. However, this term can be misleading because the nuclei of the reticular formation are involved sleep, attention, movement, the maintenance of muscle tone, and various cardiac, circulatory, and respiratory reflexes. Metencephalon The......

...1. Does the company’s strategy reflect the company’s mission? Explain. Whole Food’s mission is based on three categories, the food, the people and the planet. They believe in providing natural whole foods through highly trained and passionate employees with the company taking active responsibility for the planet. It is apparent, when examining the company, that their business practices reflect their mission. Using their Product Quality Standards documents as a guideline, it is clear Whole Foods carefully considers which products they do or do not sell. Their buyers often visit the manufacturing plants of suppliers to ensure high standards. In addition to their commitment of only carrying foods that are “free of artificial preservatives, colors, flavors, sweeteners and hydrogenated fats” (Whole Foods Market, 2012), they also maintain a list of unacceptable ingredients which include standards like “artificial colors, artificial flavors, hydrogenated fats and high fructose corn syrup” (Whole Foods Market, 2012) and they do not carry products that contain those ingredients. Within the store, Whole Foods takes a team based approached to individual store management and success. Team members are organized around team leaders, which are responsible and empowered to make decisions such as merchandising and operations. Team members are also provided with other avenues for feedback such as an annual survey on employee benefit packages and survey on team leaders. ......

...The Brain The brain is the most complex organ in the human body. It is the control center for the everyday activities we take part in. Being in the central nervous system, the brain receives messages from all parts of the body, and then sends a message back to the body telling it how to respond to the situation. But, the brain is made of different parts and each of these parts does their own separate job for making the brain run smoothly. The cerebral hemispheres are made up of five lobes, the frontal, parietal, temporal, and the insula. These lobes are the parts of the brain, which control speech, logic, imagination and so much more. The cerebral hemispheres also control voluntary movement, conscious awareness of sensation, and integrate diverse information. The information that is delivered through the brain must go through the thalamus first. The thalamus acts like a relay station for the brain, all the sensory messages go to the thalamus and get sorted out before going to the cerebral hemispheres. Another role the thalamus has is in the memory and learning aspect that humans need to develop their brain. Below the thalamus is the hypothalamus, and the hypothalamus controls many visceral functions. It regulates your blood pressure, the rate of your heartbeat, and the rate at which you breathe. Also, the hypothalamus maintains the body temperature, and regulates both hunger and sleep, which are needed to maintain homeostasis. Towards the back of the brain, the......

...Journey of the brain-Birth to late adulthood Child development is crucial throughout the early years, during this time the development of the brain occurs and continues through late adulthood. The development of the brain contributes to the functioning of the body. The anatomy of the brain is made up of neurons and divided into four different lobes. The temporal, frontal, parietal, and occipital lobes control a variety of cognitive functions (Santrock, 2013). The brain controls simple functions such as fine and gross motor skills, vision, and memory. For instance the frontal lobes are involved in the voluntary movement, thinking, personality, and intentionality or purpose. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language processing and memory. The parietal lobes plays role in registering spatial location, attention and motor control. (Santrock, 2013). Brain development in children is vital during the early years. During the early years, children brains are active enabling children to learn a variety of information. However, as individual ages there are changes in the brain which influence cognitive functioning learned throughout the years of development. At birth the newborn’s brain is about 25 percent of its adult weight; by the 24 months the brain is about 75 percent of its adult weight (Santrock, 2013). The brain is very delicate and needs a lot of protection for its......

...Bennett The Brian The brain is consisting of three main sections. They are the forebrain, the midbrain and the hindbrain. These are connected to the central nervous system of the spinal cord (Pinel, 2011). The three sections of the brain can be subdivided into five main structures. The forebrain is where the two main structures reside; this includes the telencephalon and diencephalon which are located within the central nervous system. The midbrain is where the mesencephalon is located along with the hindbrain; the forebrain has the two final structures which are metencephalon and myelencephalon these main structures reside within the central nervous system of the brain (Pinel, 2011). The Myelencephalon, which is known as the medulla, that is located in the hindbrain, this, is the most position part of the brain. The medulla of the brain is the main structure that can carry signals throughout the entire body (Pinel, 2011). The medulla is responsible for the reticular that controls information within the brains central nervous system. The reticular information can be a complex network of the white and gray matter; this can smooth the transition between the descending and ascending signals of the central nervous system within the myelencephalon. The reticular information affects other functions of the body that includes sleep, movements, and arousal. The myelencephalon along with its reticular information can process structures of the brain that can become more......

...The Brain- Introduction The brain is an amazing organ. It monitors, regulates, initiates basic drives, stores and retrieves information, performs intellectual functions, produces and interprets language, processes visual and auditory data, and, it's only the size of a coconut. The brain works using a vast connection of nerve cells, billions in fact, that connects with billions of other nerve cells. To get a visual of the parts of your brain, hold up your hand. Place your thumb across your palm and then close your fingers over your thumb. There is your brain. Your arm is the brain stem or messenger from the brain. The outer part of your hand is the cortex. This is where rational thinking occurs. You fingers that are bent over your thumb represent your frontal cortex. Here is where parasympathetic and sympathetic responses live as well as your executive functioning such as thoughts on right and wrong and decision-making. If you lift your fingers you see your thumb. This represents the limbic system. The limbic system is a very important part of mental health nursing. Here is where the amygdala lives which controls anger and sadness. The hippocampus is also here, which is part of memory. Overall, the limbic system controls emotion and plays a role in addiction. Notice that when you close your fingers, or your frontal lobe, over your thumb, they touch. What does that mean? Well, the limbic system and frontal cortex affect each other. Remember that the brain forms from back to...

They had been together ever since the beginning of their college year, though this had been a secret kept from her parents. The idea of Muslim girl marrying a Hindu boy would never be deemed acceptable or appropriate by them. When she finally garnered the courage to request them to fulfill her desire, her parents were aghast. Isra’s father was taken aback, and questioned her intentions. “How could you even think of such a thing? We are Muslims, and marrying you off to Hindu boy is considered haram.” A similar response was received from her mother, when she reacted; “Do you even know of the consequences of such an act? We will be shunned by the Muslim society, and moreover, we will lose all our respect.” As a result, Isra was denied any further meeting with the love of her life, and was bound to her room until further notice. Isra was devastated, and ran to her room in despair. She knew for her parent’s sake and their family’s reputation that she had to cut all ties with Mihir. In an attempt to explain the unfolding situation, she sent him an email citing reasons for why they could no longer be together...

...The Brain Terrie Oliver Axia College of University of Phoenix The Brain The brain is part of the central nervous system, which is located in the skull, and a very complex organ, with massive information data that flows throughout the body. The brain is like a hard-drive: storing daily active, awareness, memory, emotions, and reason. The brain is where decision-making is done, right, or wrong, what could have been, or should have been. The brain with all its mysterious complexities, and abilities, is one of the most study organs in the human body. The brain is divided into five divisions: the forebrain contains the Telencephalon, and the Diencephalon. In the midbrain we find the Mesencephalon, and in the hindbrain the Metencephalon, and the Myelencephalon are found. These five structures also contain divisions in their selves adding to the complexity of the human brain as we discus their functions (Pinel, 2007). The Telencephalon The Telencephalon, or cerebrum as referred to by many people, is located in the forebrain, divided into two hemispheres, is the largest of the structures, and can be compared to junction box at a train depot. Train cars are like the sensory input, and output that goes into the telencephalon, which like the junction box directs these senores, or train cars where to go. These functions could be voluntary movement, learning, solving issues, or problems, and speaking. There are other divisions found in the telencephalon and they......

...The Brain and Behavior Essay The brain is an organ that serves as the center of the nervous system in all vertebrate. The function of the brain is to exert centralized control over the other organs in the body. Contrasting the roles of behavior of the temporal and frontal lobe seems to be quite interesting. Temporal lobe is one of four major lobes of the cerebral cortex. This particular lobe is responsible for the retention of the visual memories, processing sensory, comprehending language, storing and emotions. The frontal lobe is located in the front of the brain. It contains most of the dopamine sensitive neurons in the cerebral cortex. It has similarities of the temporal lobe. Some of the behaviors that the frontal lobe is responsible for are conscious thought, voluntary movement and a person individual personality characteristics. Any damages to either frontal can cause a change in a person’s emotions, they become less motivated to do anything and they become very aggressive in their behavior. Paul Broca did a study that involved language in 1861.His first studied was a deceased patient that had a problem that caused him not to speak nor express his thoughts in writing. He came to find out the he had a small size lesion on the left inferior frontal cortex. After several other studies he discovered that they all had a small lesion and this is when he made the statement “We speak with the left hemisphere” and identify the existence of a “language centre” in the posterior......

...The brain is the most complex organ in the human body. The brain produces our every thought, action, memory, and feeling. It controls our voluntary movements, and it regulates involuntary activities such as breathing and heartbeat. The Brain is a jelly like mass of tissue, weighing in at around 3 pounds, and constitutes about 2 percent of total body weight but uses 20 per cent of the oxygen used by the entire body when at rest. The brain can go without oxygen for only three to five minutes before serious damage results. The brain contains a staggering one hundred billion nerve cells, or neurons. The left hemisphere of the brain controls the right side of the body while the right hemisphere of the brain controls the left side of the body. Our brains are made mostly of water 78 percent, fat 10 percent, and protein 8 percent. A living brain is so soft that you could cut it with a butter knife. The brain is not just a mass of tissue; the brain serves as the seat of human consciousness: it stores our memories, enables us to feel emotions, and gives us our personalities. In short words the brain dictates the behaviors that allow us to survive and makes us who we are. The brain consists of three major divisions: (1) the massive paired hemispheres of the cerebrum, which include the Frontal, Parietal, Occipital, and Temporal Lobes on the left and right hemispheres. (2) The brainstem, consisting of the thalamus, hypothalamus, epithalamus, subthalamus, midbrain, pons, and medulla...

The Brain

...The Brain Professor Mancuso Psy/240 March 26, 2016 Our human brain is responsible for all our thoughts and movement that the body produces and is the largest and most complex organ in the human body. Which is composed of trillions of connections that all work together called synapse. The adult brain weighs about 3 pounds, which is a major growth being that the human brain weighs about 350 grams at birth. The brain is made up of nerve cells that interact with the rest of the body through the spinal cord and nervous system. The nerve cells transfer information back to the center of the brain where information is processed, generated and appropriately acted upon. Without the human brain we wouldn’t be able to move speak or understand different things. The brain can be divided into the forebrain, mid brain and the hindbrain. But there is five major structures of the brain, which are Myelencephalon, Metencephalon, Mesencephalon, Diencephalon and Telencephalon. Myelencephalon also known as medulla, is the most posterior division of the brain. Myelencephalon is composed of tracts that carry signals between the rest of the brain and the body. It’s complex network of about 100 tiny nuclei which occupies the central core of the brain stem from the posterior boundary of the midbrain. The tiny nuclei are very important they are responsible for many things such as movement, maintenance of muscle tone, attention and even us sleeping.......

...The Brain The brain is one of the most complex and magnificent organs in the human body. Our brain gives us awareness of ourselves and of our environment, processing a constant stream of sensory data. It controls our muscle movements, the secretions of our glands, and even our breathing and internal temperature. Every creative thought, feeling, and plan is developed by our brain. The brain’s neurons record the memory of every event in our lives. Anatomy of the brain There are different ways of dividing the brain anatomically into regions. Let’s use a common method and divide the brain into three main regions based on embryonic development: the forebrain, midbrain and hindbrain. Under these divisions: The forebrain (or prosencephalon) is made up of our incredible cerebrum, thalamus, hypothalamus and pineal gland among other features. Neuroanatomists call the cerebral area the telencephalon and use the term diencephalon (or interbrain) to refer to the area where our thalamus, hypothalamus and pineal gland reside. The midbrain (or mesencephalon), located near the very center of the brain between the interbrain and the hindbrain, is composed of a portion of the brainstem. The hindbrain (or rhombencephalon) consists of the remaining brainstem as well as our cerebellum and pons. Neuroanatomists have a word to describe the brainstem sub-region of our hindbrain, calling it the myelencephalon, while they use the word metencephalon in reference to......

Lan Emulation

...LAN Emulation Overview This overview gives a high-level description of LAN Emulation (LANE). LAN Emulation (LANE) Implementation of LANE makes an ATM interface look like one or more Ethernet interfaces. LANE is an ATM service defined by the ATM Forum specification LAN Emulation over ATM, ATM_FORUM 94-0035. This service emulates the following LAN-specific characteristics: • Connectionless services • Multicast services • LAN media access control (MAC) driver services LANE service provides connectivity between ATM-attached devices and connectivity with LAN-attached devices. This includes connectivity between ATM-attached stations and LAN-attached stations and also connectivity between LAN-attached stations across an ATM network. Because LANE connectivity is defined at the MAC layer, upper protocol layer functions of LAN applications can continue unchanged when the devices join emulated LANs. This feature protects corporate investments in legacy LAN applications. An ATM network can support multiple independent emulated LAN networks. Membership of an end system in any of the emulated LANs is independent of the physical location of the end system. This characteristic enables easy hardware moves and location changes. In addition, the end systems can also move easily from one emulated LAN to another, whether or not the hardware moves. LAN emulation in an ATM environment provides routing between emulated LANs for supported routing protocols and high-speed,...

...The Brain The brain weighs about three pounds and involves about 10 million neurons ("Major Structures of the Brain", 2008). Cells that support the brain system are known as Glial cells. The brain consists of three major divisions known as the forebrain, the midbrain, and the hindbrain ("Major Structures of The Brain", 2008). The neurons in the brain process information and are the nervous systems transmitting device. Most neurons are broken down into four structures: o The Soma – the cell body which houses and protects the nucleus. o The Dendrite – the branch-like mechanism that the neuron receives information through. o The Axon – the long, thin tube-like structure that carries the information sent from the soma to the terminal buttons. o Terminal Buttons – small knob-like structures at the end of each branch of the axon. These buttons secrete neurotransmitters. The forebrain consists of the telencephalon and the diencephalon. The midbrain consists of the mesencephalon which is then broken down into the tectum and the tegmentum. The hindbrain consists of the metencephalon which is broken down into the cerebellum, pons, and the myelencephalon which is comprised of the medulla oblongata. The telencephalon is at the anterior part of the brain and is made up of the basil ganglia, the cerebral cortex, the olfactory bulb, and the corpus striatum. The functions of the telencephalon are: o Determines Intelligence o Determines Personality o Interprets Sensory......
