Dual Ca2+ modulation of glycinergic synaptic currents in rodent hypoglossal motoneurones.
Glycinergic synapses are implicated in the coordination of reflex responses, sensory signal processing and pain sensation. Their activity is pre- and postsynaptically regulated, although mechanisms are poorly understood. Using patch-clamp recording and Ca2+ imaging in hypoglossal motoneurones from rat and mouse brainstem slices, we address here the role of cytoplasmic Ca2+ (Ca(i)) in glycinergi...
متن کاملDynamic interactions of excitatory and inhibitory inputs in hypoglossal motoneurones: respiratory phasing and modulation by PKA.
The balance of excitation and inhibition converging upon a neurone is a principal determinant of neuronal output. We investigated the role of inhibition in shaping and gating inspiratory drive to hypoglossal (XII) motoneuronal activity. In neonatal rat medullary slices that generate a spontaneous respiratory rhythm, patch-clamp recordings were made from XII motoneurones, which were divided into...
متن کاملNoradrenergic Activation of Hypoglossal Nucleus Modulates the Central Regulation of Genioglossus in Chronic Intermittent Hypoxic Rats
Neuromuscular compensation of the genioglossus muscle can be induced by chronic intermittent hypoxia (CIH) in obstructive sleep apnea to maintain upper airway stability. Noradrenergic activation of hypoglossal nucleus plays a critical role in the central control of the genioglossus. However, it remains unknown whether norepinephrine takes part in the central regulation of the genioglossus durin...
متن کاملHypoglossal Schwannoma in Submandibular Space
Schwannoma of the hypoglossal nerve is an uncommon benign neoplasm. We present a 49-year-old female patient with hypoglossal schwannoma presenting as a painless mass in the submandibular area.
متن کاملCommon inhibitory motoneurones in insects.
Motor nerve fibres to insect muscles are usually classified as either fast, slow or inhibitory, depending on the mechanical and electrical responses they elicit in the muscle (Hoyle, 1953a; Usherwood, 1962; Usherwood & Grundfest, 1964), although some motor axons cannot be satisfactorily placed within any of these categories (Hoyle, 1959, 19666). Histologically, single insect muscles have been s...
