Age-related hearing loss (presbycusis) is a complex state that reflects pathologic changes
along the entire auditory neuraxis. Loss of speech understanding, decreased ability to …

Spatial hearing, and more specifically the ability to localize sounds in space, is one of the
most studied and best understood aspects of hearing. Because there is no coding of …

Duration is a biologically important feature of sound. Some neurons in the inferior colliculus
of the big brown bat, Eptesicus fuscus, are tuned to sound duration, but it is unclear at what …

The perception of complex sounds, such as speech and animal vocalizations, requires the
central auditory system to analyze rapid, ongoing fluctuations in sound frequency and …

The inferior colliculus (IC)(Fig. 7.1) occupies a strategic position in the central auditory
system. Evidence reviewed in this chapter indicates that it is an interface between lower …

The inferior colliculus receives excitatory and inhibitory input from parallel auditory pathways
that differ in discharge patterns, latencies, and binaural properties. Processing in the inferior …

Excitatory and inhibitory frequency response areas of 130 neurons of the central nucleus of
the mouse inferior colliculus (ICC) were mapped by extracellular single-unit recordings and …

A decline in the ability to discriminate speech from noise due to age-related hearing loss
(presbycusis) may reflect impaired auditory information processing within the central …

The inferior colliculus (IC) is a major auditory structure that integrates synaptic inputs from
ascending, descending, and intrinsic sources. Intracellular recording in situ allows direct …

This is a survey of the distribution, form, and proportion of neurons immunoreactive for
gamma‐aminobutyric acid (GABA) or glutamic acid decarboxylase (GAD) in cat primary …
