The Medial Nucleus of the Trapezoid Body in the Gerbil Is More Than a Relay: Comparison of Pre- and Postsynaptic Activity

Findings show that transmission at the CN–MNTB synapse does not occur in a fixed one-to-one manner and that the response of MNTB neurons reflects the integration of their excitatory and inhibitory inputs.

Decreased Temporal Precision of Auditory Signaling in Kcna1-Null Mice: An Electrophysiological Study In Vivo
Results indicate that in Kcna1-null mice the absence of the Kv1.1 subunit results in a loss of temporal fidelity (increased jitter) and the failure to follow high-frequency amplitude-modulated sound stimulation in vivo.

Ontogeny of tonotopic organization of brain stem auditory nuclei in the chicken: Implications for development of the place principle
The morphological development of the cochlea begins in the base or midbasal region and spreads toward the apex and predicts that responses to sound should occur initially to high frequencies and gradually change to include lower frequencies.

The Development of Cochlear Function
The task of determining the extent to which maturational changes in auditory perception, spontaneous activity, and central responses to sound originate within the cochlea and to what degree these changes reflect the development of central synaptic processes remains a formidable challenge.

Deafferentation increases the intracellular calcium of cochlear nucleus neurons in the embryonic chick.
The data suggest that deregulation of [Ca2+]i homeostasis plays a key role in NM neuron degeneration and death following activity deprivation.

Activity-dependent regulation of [Ca2+]i in avian cochlear nucleus neurons: roles of protein kinases A and C and relation to cell death.
The results suggest that eighth nerve activity maintains[Ca2+]i of NM neurons at physiological levels in part via mGluR-mediated activation of PKA and PKC and that increases in [Ca2-]i due to activity deprivation or interruption of the PKAand PKC regulatory mechanisms are predictive of subsequent cell death.
