DOI: 10.1002/cne.24095
Abstract: Ascending projections of the dorsal cochlear nucleus (DCN) target primarily the contralateral inferior colliculus (IC). In turn, the IC sends bilateral descending projections back to the DCN. We sought to determine the nature of these… read more here.

DOI: 10.1007/s00429-019-01979-6
Abstract: The multimodal lateral cortex of the inferior colliculus (LCIC) exhibits a modular-extramodular micro-organization that is evident early in development. In addition to a set of neurochemical markers that reliably highlight its modular-extramodular organization (e.g. modules:… read more here.

DOI: 10.1007/s11431-016-9044-5
Abstract: In studies of auditory perception, a dichotomy between envelope and temporal fine structure (TFS) has been emphasized. It has been shown that frequency-following responses (FFRs) in the rat inferior colliculus can be divided into the… read more here.

DOI: 10.1016/j.alcohol.2017.07.007
Abstract: We previously reported increased current density through P-type voltage-gated Ca2+ channels in inferior colliculus (IC) neurons during alcohol withdrawal. However, the molecular correlate of this increased P-type channel current is currently unknown. Here, we probe… read more here.

5-Hydroxytryptamine 2A receptors of the dorsal raphe nucleus modulate panic-like behaviours and mediate fear-induced antinociception elicited by neuronal activation in the central nucleus of the inferior colliculus

DOI: 10.1016/j.bbr.2017.07.016
Abstract: &NA; It has been established that chemical stimulation of the inferior colliculus (IC) of laboratory animals evokes fear‐related defensive responses, which are considered panic attack‐like behaviours. In addition, there is evidence that defensive reactions provoked… read more here.

Neuroplastic change of cytoskeleton in inferior colliculus after auditory deafferentation

DOI: 10.1016/j.heares.2018.06.010
Abstract: ABSTRACT Neural plasticity is a characteristic of the brain that helps it adapt to changes in sensory input. We hypothesize that auditory deafferentation may induce plastic changes in the cytoskeleton of the neurons in the… read more here.

DOI: 10.1016/j.heares.2019.107844
Abstract: We examined the sensitivity of the neurons in the mouse inferior colliculus (IC) to the interaural time differences (ITD) conveyed in the sound envelope. Utilizing optogenetic methods, we compared the responses to the ITD in… read more here.
