A Case of Anterior Choroidal Artery Occlusion and Stroke Secondary to External Compression

Case Reports in Neurology, 2021
The anterior choroidal artery (AChA) is a small artery commonly arising from the supraclinoid segment of the internal carotid artery (ICA). The significance of the AChA is related to its strategic supply to various important structures of the brain, such

Imaging of nerve injury in neonatal acute bilirubin encephalopathy using 1H-MRS and Glu-CEST techniques

Frontiers in Neuroscience, 2023
ObjectivesTo investigate the significance of proton magnetic resonance spectroscopy (1H-MRS) and glutamate chemical exchange saturation transfer (Glu-CEST) techniques in assessing the condition and prognosis of acute bilirubin encephalopathy patients and

Hippocampus Modulates Vocalizations Responses at Early Auditory Centers

NeuroImage, 2023
Despite its prominence in learning and memory, hippocampal influence in early auditory processing centers remains unknown. Here, we examined how hippocampal activity modulates sound-evoked responses in the auditory midbrain and thalamus using ...

Inhibitory Projections in the Mouse Auditory Tectothalamic System

Brain Sciences, 2018
The medial geniculate body (MGB) is the target of excitatory and inhibitory inputs from several neural sources. Among these, the inferior colliculus (IC) is an important nucleus in the midbrain that acts as a nexus for auditory projections, ascending and

Corticothalamic gating of population auditory thalamocortical transmission in mouse

eLife, 2021
The mechanisms that govern thalamocortical transmission are poorly understood. Recent data have shown that sensory stimuli elicit activity in ensembles of cortical neurons that recapitulate stereotyped spontaneous activity patterns.

Thalamic, cortical, and amygdala involvement in the processing of a natural sound cue of danger.

PLoS Biology, 2020
Animals use auditory cues generated by defensive responses of others to detect impending danger. Here we identify a neural circuit in rats involved in the detection of one such auditory cue, the cessation of movement-evoked sound resulting from freezing.

Learning-related population dynamics in the auditory thalamus

eLife, 2020
Learning to associate sensory stimuli with a chosen action involves a dynamic interplay between cortical and thalamic circuits. While the cortex has been widely studied in this respect, how the thalamus encodes learning-related information is still ...

Drivers and modulators in the central auditory pathways

Frontiers in Neuroscience, 2010
The classic view of auditory information flow depicts a simple serial route from the periphery through tonotopically-organized nuclei in the brainstem, midbrain and thalamus, ascending eventually to the neocortex.

The Effects of Acoustic White Noise on the Rat Central Auditory System During the Fetal and Critical Neonatal Periods: A Stereological Study

Noise and Health, 2017
Aim: To evaluate the effects of long-term, moderate level noise exposure during crucial periods of rat infants on stereological parameters of medial geniculate body (MGB) and auditory cortex.

Can chronic remote cortical hypoperfusion induced by thalamic infarction cause damage of tracts passing through those hypoperfused regions?

Frontiers in Neurology, 2013
We report the case of a woman presenting with changes on cerebral imaging a year and a half after a bi-thalamic (predominantly left-sided) infarction including lateral and medial thalamic nuclei.
