TEMPORAL AND BEHAVIORAL CONSTRAINTS ON PLASTICITY

Project: Research project

Project Details

Description

Cortical area 3b contains representations of the surfaces of the digits
that are adjacent and non-overlapping in untrained owl monkeys. Recent
work in the Merzenich laboratory has shown that simultaneous or
alternating stimulation of the digits in a behavioral task causes the
neural representations of these digits to merge or to segregate,
respectively. In the proposed experiments we ask under what temporal
and behavioral conditions will the neural representations of stimuli
merge?

Owl monkeys have been trained at tasks that present stimuli to adjacent
distal fingerpads with near simultaneous stimulus timing. Awake
behaving recordings will allow us to document the cortical changes that
accompany changes in the animal's perceptual capabilities. The awake
recordings will answer questions about the temporal and behavioral
conditions under which single cortical neurons re-organize their spatial
and temporal response properties.
