Peripheral encoding
In light of the spatio-temporal nature of the world
around us, it is not surprising that sensory encoding
is based on spatial and temporal cues that encode
static and dynamic events. Spatial encoding of the
world is accomplished by arrays of receptors, which
are spatially organized across the sensory organs.
Each receptor is most sensitive to a specific and
limited range within the sensation spectrum. For ex-
ample, each hair cell in the cochlea is most sensitive
to a limited range of acoustic frequencies, which
is mapped to a specific location along the cochlea.
