The basic anatomical unit in the Nervous System is a specialized Cell called the Neuron . Functions Of Neurons Metabolic machinery within the cell provides a power source, for information processing functions. In addition, the cell enforces a certain unity, for biochemical mechanisms throughout its extent. These Synaptic contacts are the primary information processing elements in Neural Networks.
Processes are similar to wires, conveying information over a finite distance.
The resistance of finer Dendrites allows the electrical potential at their tips, to be computed with only partial coupling, to other computations in the Dendrite Tree. Temporal integration of signals occurs over the short term, through charge storage within the capacitance of the cell membrane, and over the longer term, by means of internal second messengers and biochemical mechanisms. The classical Neuron is equipped with a tree of filamentary Dendrites that aggregate Synaptic inputs from other Neurons. At which point an output is generated in the form of a Nerve Pulse - the Action Potential . This output pulse propagates down the Axon, which ends in a tree of Synaptic contacts to the Dendrites of other Neurons.
