Nearly sixty years ago Fredrich Timm developed a histochemical technique that revealed a
rich reserve of free zinc in distinct regions of the brain. Subsequent electron microscopy …

The role of the cochlea is to transduce complex sound waves into electrical neural activity in
the auditory nerve. Hair cells of the organ of Corti are the sensory cells of hearing. The inner …

The shapes of the head and ears of mammals are asymmetrical top-to-bottom and front-to-
back. Reflections of sounds from these structures differ with the angle of incidence …

Tinnitus displays many features suggestive of plastic changes in the nervous system. These
can be categorized based on the types of manipulations that induce them. We have …

Unipolar brush cells (UBC) are small, glutamatergic neurons residing in the granular layer of
the cerebellar cortex and the granule cell domain of the cochlear nuclear complex. Recent …

The vast amount of fast excitatory neurotransmission in the mammalian central nervous
system is mediated by AMPA-subtype glutamate receptors (AMPARs). As a result, AMPAR …

The cochlear nucleus contains the circuits through which information about sound is
coupled to the brain. In the cochlear nucleus, fibers of the auditory nerve contact neurons …

The auditory nerve of birds and mammals exhibits differences and similarities, but given the
millions of years since the two classes diverged from a common ancestor, the similarities are …

The composition of AMPA receptors in patches excised from somata and dendrites of six cell
types in the mammalian cochlear nuclei was probed and compared electrophysiologically …

Several mechanisms can underlie short-term synaptic depression, including vesicle
depletion, receptor desensitization, and changes in presynaptic release probability. To …
