Coordinate transformations in the representation of spatial information
 

Summary: Coordinate transformations in the representation of spatial
information

Coordinate transformations are an essential aspect of behavior. They are
required because sensory information is coded in the coordinates of
the sensory epithelia (e.g. retina, skin) and must be transformed to the
coordinates of muscles for movement. In this review we will concentrate
on recent studies of visual-motor transformations. The studies show that
representations of space are distributed, being specified in the activity of
many cells rather than in the activity of individual ceils. Furthermore, these
distributed representations appear to be derived by a specific operation,
which systematically combines visual signals with eye and head position
signals.

Introduction
Evidence from recent years has suggested that there are
intermediate and abstract representations of space inter-
posed between sensory input and motor output. Inter-
