By comparison with experimental situations where tiny areas of stimulation are used often, painful foci encountered in clinical practice are not punctuate: they presumably involve a large number of excitatory receptive fields of peripheral fibers and central neurons. Thus spatial summation may be an ...

Brunel) This works for sparse ...

Introduction to the Nervous System
... Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a ...
