Here we shall examine, in general terms how a precise circuit of interconnected neurons produce a simple behavior.
Reflexes represent the simplest forms of behavior .
A reflex is an involuntary and relatively stereotyped response to a specific sensory stimulus. Two features of the sensory stimulus are particularly important in shaping the reflex response. First, the precise location of the stimulus determines in a fixed way the particular muscle that contract to produce the reflex response. Second the strength of the stimulus determines the amplitude of the response. Reflex therefore are graded behaviors.
