Neuropathology of the Guillain-Mollaret Triangle (Dentato-Rubro-Olivary Network) in Sudden Unexplained Perinatal Death and SIDS [PDF]
The Open Neurology Journal, 2009 The present study was undertaken to evaluate the possible alterations of the triangle of Guillain and Mollaret (G-Mt), a neuronal brainstem/cerebellum network (from the dentate nucleus to red nucleus and inferior olivary nucleus) already known for its involvement in the pathogenesis of the palatal myoclonus, in sudden unexplained perinatal and infant ...

The Cerebellum in Poststroke Movement Disorders: A Case of Head Tremor Indicating a Cerebrovascular Emergency. [PDF]
Case Rep Neurol MedTremor is a common symptom encountered in outpatient practice, particularly within a neurology movement disorder clinic. However, tremor can also be pertinent to inpatient medicine and can warrant emergent evaluation. We describe a case of a 72‐year‐old female who developed acute onset postural head tremor without appendicular tremor during a hospital ...

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
