The Dentato-Rubro-Olivary Tract: Clinical Dimension of This Anatomical Pathway

Case Reports in Otolaryngology, 2013
Symptomatic palatal tremor is potentially the result of a lesion in the triangle of Guillain-Mollaret (1931) and is associated with hypertrophic olivary degeneration (HOD) which has characteristic MR findings. The triangle is defined by dentate efferents

Climbing fiber burst size and olivary sub-threshold oscillations in a network setting.

PLoS Computational Biology, 2012
The inferior olivary nucleus provides one of the two main inputs to the cerebellum: the so-called climbing fibers. Activation of climbing fibers is generally believed to be related to timing of motor commands and/or motor learning.

Hypertrophy of the Anterior External Arcuate Fasciculus: A Rare Variant With Implications for the Development of the Arcuate Nucleus

Frontiers in Neuroanatomy, 2020
A rare anatomic variant of a markedly enlarged anterior external arcuate fasciculus (AEAF) on the ventral medullary surface is reported and compared to two controls. The hypertrophic AEAF was nine times larger in diameter than normal, whereas the arcuate

Pharmacologic MRI Brain Imaging Studies of Serotonin 5‐HT1 Receptor Agonists in Awake Mice

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Serotonin (5‐hydroxytryptamine, 5‐HT) type‐1 G protein‐coupled receptors are expressed throughout the central nervous system. 5‐HT1AR activation is the putative mechanism of approved drugs for generalized anxiety disorder and major depressive disorder and is being studied in the treatment of autism and neurological disorders.

In vivo Probabilistic Structural Atlas of the Inferior and Superior Colliculi, Medial and Lateral Geniculate Nuclei and Superior Olivary Complex in Humans Based on 7 Tesla MRI

Frontiers in Neuroscience, 2019
Despite extensive neuroimaging research of primary sensory cortices involved in auditory and visual functions, subcortical structures within these domains, such as the inferior and superior colliculi, the medial and lateral geniculate nuclei and the ...

Deciphering Freezing of Gait: What Neuropathology Reveals About an Episodic Phenomenon

European Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Freezing of gait (FoG) occurs across Parkinson's disease, multiple neurodegenerative conditions and non‐neurodegenerative disorders. This review synthesizes the structural, neurochemical and proteinopathic substrates underlying FoG, showing how cumulative damage to distributed locomotor circuits—compounded by overlapping pathologies—progressively ...

Using subthreshold events to characterize the functional architecture of the electrically coupled inferior olive network

eLife, 2020
The electrical connectivity in the inferior olive (IO) nucleus plays an important role in generating well-timed spiking activity. Here we combined electrophysiological and computational approaches to assess the functional organization of the IO nucleus ...

Properties of the nucleo-olivary pathway: an in vivo whole-cell patch clamp study. [PDF]

PLoS ONE, 2012
The inferior olivary nucleus (IO) forms the gateway to the cerebellar cortex and receives feedback information from the cerebellar nuclei (CN), thereby occupying a central position in the olivo-cerebellar loop.

Unusual co-occurrence of hypertrophic inferior olivary degeneration with infratentorial cavernomatosis and orbital cavernous hemangioma

Radiology Case Reports
Hypertrophic olivary degeneration (HOD) is a rare condition resulting from a lesion in the Guillain-Mollaret triangle (GMT), causing transsynaptic degeneration and hypertrophy of the inferior olivary nucleus (ION).
