Hypertrophic olivary degeneration: A case report

Indian Journal of Radiology and Imaging, 2019
Hypertrophic olivary degeneration is a rare occurrence in which different pathological processes including enlargement and vacuolation of the neurons, demyelination of the white matter, and fibrillary gliosis of the inferior olivary nucleus take place ...

Post Mortem Image Analysis of Astrocytes of the Human Principal Olivary Nucleus Using Geometrical and Fractal Parameters

Fractal and Fractional, 2022
Based on their morphology, the most abundant cells within the nervous tissue of the central nervous system, astrocytes, can be divided into two types, protoplasmic astrocytes and fibrous astrocytes.

Subcollicular projections to the auditory thalamus and collateral projections to the inferior colliculus

Frontiers in Neuroanatomy, 2014
Experiments in several species have identified direct projections to the medial geniculate nucleus (MG) from cells in subcollicular auditory nuclei. Moreover, many cochlear nucleus cells that project to the MG send collateral projections to the inferior ...

Bilateral Hypertrophic Olivary Degeneration and Holmes Tremor without Palatal Tremor: An Unusual Association

Tremor and Other Hyperkinetic Movements, 2016
Background: Lesions in the Guillain–Mollaret triangle or dentate-rubro-olivary pathway may lead to hypertrophic olivary degeneration (HOD), a secondary trans-synaptic degeneration of the inferior olivary nucleus.

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

Advanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Hypertrophic olivary degeneration secondary to a Guillain Mollaret triangle cavernoma: Two case report

Radiology Case Reports
Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration. It is caused by a damage at the Guillain-Mollaret triangle (GMT), which is defined by three anatomical structures: the dentate nucleus, the red nucleus, and the ...

Sound offset responses become highly informative in the auditory cortex

The Journal of Physiology, EarlyView.
Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...

Tonotopically distinct OFF responses arise in the mouse auditory midbrain following sideband suppression

The Journal of Physiology, EarlyView.
Abstract figure legend Sounds of different frequencies elicit spatially distinct patterns of neural activity within the inferior colliculus aligned to the tonotopic organization of afferent projections. Sound‐evoked neural responses can be visualized in awake mice that express fluorescent Ca2+ sensors.

Molecular Ontology Predicts Output Connections From the Nucleus of the Solitary Tract

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.
The nucleus of the solitary tract (NTS) integrates visceral inputs to coordinate appetite and digestion, breathing, and cardiorespiratory reflexes. Using cell‐type‐specific tracing, we show that excitatory Lmx1b neurons project broadly to brainstem and forebrain targets, whereas inhibitory output remains largely brainstem‐restricted. Catecholaminergic (
