Neural Networks - School of Computer Science
... Multi-layer perceptrons can be trained to learn nonlinear separable functions (1980s). A typical neural network will have several layers an input layer, one or more hidden layers, and a single output layer. In practice no hidden layer: cannot learn non-linear separable one-three layers: more practic ...

Cellular Neuroanatomy II
... The diameter of an axon proper (constant radius) is variable, ranging from 1 to 25 mm; the thicker the axon, the faster the transfer of information. Axons may give off branches (called axon collaterals) (some of which may return to contact the cell itself, called recurrent) allowing neurons to commu ...

... In most animals, the synapse between two neurons are traversed by chemicals in the following steps: 1. Calcium (Ca2+) gates open. When an action potential reaches the end of an axon, the depolarization of the membrane causes gated channels to open and allows Ca2+ to enter the cell 2. Synaptic vesicl ...
