The nucleus basalis of the basal forebrain is an essential component of the
neuromodulatory system controlling the behavioral state of an animal and it is thought to be …

Cortical neurons receive balanced excitatory and inhibitory synaptic currents. Such a
balance could be established and maintained in an experience-dependent manner by …

The influence of cortical feedback on receptive field organization in the thalamus was
assessed in the primate somatosensory system. Chronic and acute suppression of neuronal …

Sensory maps in neocortex are adaptively altered to reflect recent experience and learning.
In somatosensory cortex, distinct patterns of sensory use or disuse elicit multiple, functionally …

Sensory experience in early life shapes the mammalian brain. An impairment in the activity-
dependent refinement of functional connections within developing visual cortex was …

The field of basal ganglia research is exploding on every level—from discoveries at the
molecular level to those based on human brain imaging. A remarkable series of new …

The mammalian visual cortex is organized into columns. Here, we examine cortical
influences upon developing visual afferents in the cat by altering intrinsic γ-aminobutyric …

The frontal eye field (FEF) is one of several cortical regions thought to modulate sensory
inputs. Moreover, several hypotheses suggest that the FEF can only modulate early visual …

After limited sensory deafferentations in adult primates, somatosensory cortical maps
reorganize over a distance of 1 to 2 millimeters mediolaterally, that is, in the dimension …

The cortical representation of the sensory environment is continuously modified by
experience. Changes in spatial (receptive field) and temporal response properties of cortical …
