Amygdalar Modulation of the Medial Geniculate Nucleus and Cingulate Cortex in Discriminative Avoidance Training
Neurons in A29 and the lateral nucleus of the amygdala (LA) characteristically develop maximal dTIA in late stages of DAL. Experiment II tested the hypothesis that LA nucleus is responsible for the late dTIA in A29. As hypothesized, LA nuclear excitotoxic lesions decreased dTIA in A29. Moreover, …

Neuronal Nicotinic Receptor Dynamics in Medial Geniculate Body Neurons of Young and Aged Fischer Brown Norway Rats
The medial geniculate body (MGB) is the thalamic nucleus situated between the inferior colliculus (IC) and auditory cortex (AC) in the ascending auditory pathway. It has classically been thought of as a relay station for auditory stimuli; however, we now know that is capable of significantly …

Unique Response Properties and GABA<sub>A</sub> Receptor Function in Medial Geniculate Body Neurons of Young and Aged Fischer Brown Norway Rats
The auditory thalamus or medial geniculate body (MGB) is the final brain structure for acoustic information processing prior to, and functioning in reciprocity with, auditory cortex. MGB neurons process and gate aspects of acoustic stimuli, functions which depend partly on GABAergic inhibition. To …

Classification and Processing of Communication Calls in Little Brown Bats, Myotis Lucifugus
… calls, but not for courtship calls. The medial geniculate body of the thalamus showed generally weaker expression compared to the IC, with higher expression levels for DFM and echolocation signals compared to reversed calls and silence. Results of the present egr1 studies suggest that …

Effects of cardiac gating on fMRI of the human auditory system
… in the inferior colliculus (p < 0.01) and medial geniculate body (p < 0.1).

Associative learning in auditory thalamus and amygdala
… has furthered our understanding of the roles the medial geniculate nucleus of the thalamus (MGN) and basolateral amygdala (BLA) play in the formation of associative learning, many open questions remain. MGN is often thought of as only contributing relayed sensory information, and BLA the primary …

Thalamocortical forward modulation in the auditory cortex
… stimulation (ES) of the ventral division of the medial geniculate body (MGBv, ESMGBv) substituted for one or both tones of the conventional two-tone stimulus paradigm. With this ameliorative approach, I demonstrated that ESMGBv facilitated succeeding ESMGBv while suppressing succeeding tones. …

Information Processing in the Auditory Thalamus of the Echolocating Bat, Myotis Lucifugus: Implications for Fluttering Target Detection
… the role of the intervening structure, the medial geniculate body (MGB), in producing these IC-to-AC transformations. Electrophysiological recordings from neurons in the MGB revealed that the unit selectivities to stimulus frequency and amplitude were not significantly different from those …

Modularity of the microcircuitry of the lateral cortex of the mouse inferior colliculus
… in extramodular domains, while outputs to the medial division of the medial geniculate body arise from modular regions. Taken together, these results suggest that the lateral cortex of the mouse inferior colliculus exhibits connectional as well as neurochemical modularity, and may contain …

Cell Size Distribution in the MGN and Associated Auditory Temporal Processing Deficits in P1 and P7 HI Injured Rodents
… that damage to large or “magno” cells of the medial geniculate nucleus (MGN; which are hypothesized to be responsible for encoding temporal aspects of acoustic information), may underlie or contribute to RAP deficits - - with cascading effects on both language and reading development. In …

Impact of Thalamocortical Synaptic Transmission on Input specific plasticity in Mouse Auditory Cortex
… stimulation of the ventral division of the medial geniculate body (MGBv) of the thalamus; implicating that, auditory thalamocortical system is important for frequency-specific receptive field plasticity. Up and down regulation of synaptic strength, i.e. long-term potentiation (LTP) and …
