Aging and acoustic trauma may result in partial peripheral deafferentation in the central
auditory pathway of the mammalian brain. In accord with homeostatic plasticity, loss of …

Aging is accompanied by the deterioration of hearing that complicates our understanding of
speech, especially in noisy environments. This deficit is partially caused by the loss of hair …

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 …

To ascertain whether the auditory neocortex also innervates the central nucleus of the
inferior colliculus (CNIC) and not only its dorsal (DCIC) and external (ECIC) cortices, the …

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 …

Central tinnitus is used herein either to designate a tinnitus that originates in the central
auditory system, or to refer to a component of a peripherally generated tinnitus that is …

The processing of biologically important sounds depends on the analysis of their frequency
content by the cochlea and the CNS. GABAergic inhibition in the inferior colliculus shapes …

The auditory modality is fundamentally a temporal sense that requires analysis of changes
in sound signals on timescales ranging from microseconds to minutes. To generate a faithful …

Following restricted peripheral damage, reorganization of adult sensory or motor cortex is
believed to depend on loss of surround inhibition, which unmasks latent inputs to the …
