Document Summary

The neuron the human brain consists of roughly 100 billion neurons and roughly 100 trillion synapses neurons - cells in the nervous system that communicate with one another to perform information-processing tasks. Camillo golgi and santiago ramon y cajal jointly awarded the nobel prize in recognition of their work on the structure of the nervous system. The neuron doctrine the nervous system is composed of discrete, individual cells neurons are the basic structural ad functional unit of the nervous system. Parts of the neuron glial cells - provide support and nutrients to neurons capable of communicating with one another/neurons. Resting / action potential resting potential - difference in electric charge between the inside and outside of a neuron"s cell membrane (-70 mv) work by biologists alan hodgkin and andrew huxley. Epsp (+)excitatory signal - drives closer to action potential. Ipsp (-) inhibitory signal - moves further from action potential.
