engineer the human brain and recreate it at the cellular level inside a computer simulation. The research involves studying slices of living brain tissue using microscopes and patch clamp electrodes. Data is collected about all the many different neuron types. The simulations are carried out on a Blue Gene supercomputer built by IBM‚ hence the name "Blue Brain". Actors Behind the scene Alan Turing (1912-1954) started to build the Brain but ended up with a computer.. In 1952 ‚ Hodgkin & Huxley

between the end of a muscle and the tendon that attaches to the joint. As muscle contract the amount of collagen being active increases and the neuron branches detect this. Muscle spindles lie encased in the muscle sheath and consist of two bobbin like strictures which are separately innervated by free nerve endings. There are two types of afferent neurons here with varying actions.

Leger Neurons - Neurons are nerve cells that are located in the nervous system‚ the main function of the neurons is to send and transmit messages so that we may function and move. Dendrite – Are located on neurons and they look like tree shape stems‚ they are what sends the signals out from the neuron and they also receive signals along with sending electrical stimulations to the soma. Synaptic Gap – This is a small gap between the cell membrane and the synapse it separates the neurons and allows

reason the endocrine and nervous system releases off neurons to help to signal when something is happening. Neurons are the nerve cell that sends signals throughout the nervous and endocrine systems. For example‚ neurons measure body temperature to keep the body in normal range. It also detects negative feedback in the body to counteract a change (colbert2009pg.323). Another example‚ for instance a person burned his hand on an oven‚ the neurons communicates with the nervous system by alerting the

characteristics. Neurons - Dendrites receive information and send it toward the cell body. - The Cell body makes the material necessary for the neuron’s growth and maintenance. - The Axon carries information from the cell body to other cells. Neurotransmitters Neurotransmitters carry information across the synaptic gap to the next neuron by opening the channel on the receptor site‚ triggering the neuron to fire. Neurotransmitters can also inhibit neurons from firing. - GABA keeps many neurons from firing

existence of these cells that even different schools can agree upon their existence. A nerve cell‚ also known as a neuron‚ is defined as “Any of the impulse conducting cells that constitute the brain‚ spinal column and nerves‚ consisting of a nucleated cell body with one or more dendrites and a single axon.” (thefreedictionary.com.) the dictionary defines an axon as “the long portion of a neuron that conducts impulses away from the body of the cell. Also called nerve fibre” (thefreedictionary.com) the definition

In this case the man suffers from a sympathetic preganglionic lesion‚ and the neurotransmitter needed in order to communicate with the postganglionic neuron is Ach. (12) To create an excitatory response in the cholinergic-nicotinic receptor without having the neuron release the neurotransmitter‚ doctors can administer a nicotinic agonist in order to make the transmission of the signal possible. The nicotinic drug will mimic the action of Ach. (5‚13) Unfortunately‚ recreating Ach action could create
