Projections from auditory cortex (AC) affect how cells in both inferior colliculi (IC) respond to acoustic stimuli. The large projection from the AC to the ipsilateral IC is usually credited with the effects in the ipsilateral IC. The circuitry…
Projections from auditory cortex (AC) can alter the responses of cells in the inferior colliculus (IC) to sounds. Most IC cells show excitation and inhibition after stimulation of the AC. AC axons release glutamate and excite their targets, so…
Listeners with hearing loss have difficulty processing sounds in noisy environments. This is most noticeable for speech perception, but is reflected in a basic auditory processing task: detecting a tonal signal in a noise background, i.e.,…
The relationship between behavioral and neural performance has been explored in adult animals, but rarely during the developmental period when perceptual abilities emerge. We used these naturally occurring changes in auditory perception to evaluate…
Combination-sensitive neurons serve as the fundamental processing unit in Sussman and colleagues' proposal for the neural representation of of stop consonants. This commentary describes recent studies in the mustached bat that show how ubiquitous and…
This study examined projections to combination-sensitive neurons in the medial geniculate body of the mustached bat, These specialized neurons respond to the combination of two temporally and spectrally distinct components of the bat's sonar pulse…
Vocal communication is an important aspect of guinea pig behaviour and a large contributor to their acoustic environment. We postulated that some cortical areas have distinctive roles in processing conspecific calls. In order to test this hypothesis…
