Reversible Hearing Impairment Due to Inferior Colliculi Compression by a Pineal Glial Cyst. [PDF]
Pineal glial cysts associated with bilateral hearing impairment are very rare. Here, we present the case of a 13-year-old boy with a pineal cyst, which caused severe bilateral hearing impairment persisting from 6 years of age. When the patient was 6 years old, the bilateral hearing acuity was about 40 dB on audiometry.

Conservation of Neuron-Astrocyte Correlated Activity in Developing Sensory Pathways. [PDF]
Astrocytes and neurons in the superior colliculus exhibit spatiotemporal correlated activity before eye opening. Each neuronal wave is followed by a calcium wave in astrocytes. Spillover of glutamate activates mGluR5 and mGluR3 in astrocytes. ABSTRACT Neurons in developing sensory organs exhibit prolonged burst firing before the onset of sensory ...

Divergent and point-to-point connections in the commissural pathway between the inferior colliculi. [PDF]
AbstractThe commissure of the inferior colliculus interconnects the left and right sides of the auditory midbrain and provides the final opportunity for interaction between the two sides of the auditory pathway at the subcortical level. Although the functional properties of the commissure are beginning to be revealed, the topographical organization of ...

Wernicke Encephalopathy Complicating a Distinctive POLG Phenotype With MNGIE-Like Features. [PDF]
ABSTRACT Background Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an extremely rare autosomal recessive disease caused by variants in the thymidine phosphorylase gene (TYMP), primarily characterized by severe gastrointestinal and neurological symptoms.

The auditory cortex sends massive projections to the inferior colliculus, but the organization of this pathway is not yet well understood. Previous work has shown that the corticocollicular projection emanates from both layers 5 and 6 of the auditory ...

Increased Resting-State Positron Emission Tomography Activity After Cochlear Implantation in Adult Deafened Cats [PDF]
Objectives. Cochlear implants are widely used for hearing rehabilitation in patients with profound sensorineural hearing loss. However, Cochlear implants have variable results, and central neural plasticity is considered to be a reason for this ...

The Ventral Tectal Longitudinal Column: A Midbrain Nucleus for Modulation of Auditory Processing in the Cochlear Nucleus, Superior Olivary Complex, and Inferior Colliculus. [PDF]
The ventral tectal longitudinal column (TLCv) is a midbrain nucleus thought to provide multisensory modulation of acoustic processing via descending projections to the superior olivary complex. We discovered additional projections from the TLCv to the cochlear nucleus and to the inferior colliculus.

Nps-Expressing Neurons Receive Extensive Input From Auditory Brainstem Nuclei. [PDF]
Nps‐expressing neurons receive input from auditory brainstem nuclei, with additional afferents from the reticular formation, midbrain, hypothalamus, and extended amygdala. While rabies retrograde labeling in the cerebral cortex was sparse, cholera toxin beta (CTb) revealed copious input, and anterograde tracing identified many axons and boutons ...
