Numbers and proportions of GABA-immunoreactive neurons in different areas of monkey cerebral cortex
The number and proportion of neurons displaying GABA immunoreactivity were determined for 50-micron-wide columns through the thickness of 10 areas of monkey cerebral cortex, including the precentralExpand

Corticofugal shaping of frequency tuning curves in the central nucleus of the inferior colliculus of mice.
Plasticity of the auditory cortex can be induced by conditioning or focal cortical stimulation. The latter was used here to measure how stimulation in the tonotopy of the mouse primary auditoryExpand

  • 1 July 2002
An understanding of the neural mechanisms responsible for auditory information processing is incomplete without a careful examination of substantial descending pathways. This study focuses on theExpand

Corticofugal Modulation of Initial Sound Processing in the Brain
The brain selectively extracts the most relevant information in top-down processing manner. Does the corticofugal system, a “back projection system,” constitute the neural basis of such top-downExpand

Corticofugal feedback for auditory midbrain plasticity elicited by tones and electrical stimulation of basal forebrain in mice
The auditory cortex (AC) is the major origin of descending auditory projections and is one of the targets of the cholinergic basal forebrain, nucleus basalis (NB). In the big brown bat, corticalExpand

Corticofugal reorganization of the midbrain tonotopic map in mice
Previous studies have indicated that frequency maps (tonotopies) in mammalian auditory brain centers are plastic. Here, we examined this plasticity in the mouse auditory midbrain through focalExpand

The midbrain creates and the thalamus sharpens echo-delay tuning for the cortical representation of target-distance information in the mustached bat
Mustached bats emit complex biosonar 'pulses' for echolocation. A delay of an echo from the emitted pulse carries target-distance information. At the auditory periphery, distance information isExpand

Corticothalamic feedback for sound-specific plasticity of auditory thalamic neurons elicited by tones paired with basal forebrain stimulation.
Recent studies have revealed that the auditory cortex (AC) plays a crucial role in the plastic changes in the physiological properties of subcortical auditory neurons through corticofugalExpand
