a small area in the visual field which when stimulated with
light elicits responses from a single cell in the visual system.
The region of the stimulus that, when stimulated, causes a
change in the response of a sensory neurone. The region of
visual space to which neurons in the primary visual cortex are
sensitive. go to glossary index The area monitored by a single
sensory receptor. In sensory systems, the specific region of a
sensory surface that when stimulated causes a change in activity
of a neuron a small region within the entire visual field A map
of the inputs to a single neuron, e.g., those parts of the skin
of the hand that produce excitation or inhibition of a cortical
neuron (antagonistic surrounds are especially common). The
limited view of the world as seen by a single neuron. The set of
points at which specific stimuli can influence the excitability
of an individual neuron. For the somatosensory system it is the
area of skin which can affect the afferent neuron supplying it.
