Thalamic relay nucleus
Web14 Oct 2024 · Significance: We show that electrical synapse plasticity is gated by GABAB receptors in the thalamic reticular nucleus. This effect is a novel way for afferent GABAergic input from the basal ganglia to modulate thalamocortical relay and is a possible mediator of intra-TRN inhibitory effects. WebThe thalamic reticular nucleus is a shell of GABAergic neurons that surrounds these excitatory nuclei (Pinault, 2004; Crabtree, 2024; Takata, 2024). ... Recent studies outside of primary sensory thalamic areas have challenged the relay view, and ascribed a critical functional role for the thalamus in cognitive computations. ...

WebThe thalamus, an egg-shaped structure made up of thalamic nuclei, is part of the brain that relays sensory and motor signals from various locations (e.g., the basal ganglia, medial lemniscus, the retina) to the cerebral cortex. Additionally, the thalamus plays a role in alertness, sleep, and consciousness as well as learning and memory. Webdirect projection from thalamic pulvinar nucleus to amyg-dala [LeDoux, 1998; Tamietto and De Gelder, 2010] has been proposed to rapidly relay visual threat cues. More recently, communication between the central amygdala and the para-ventricular thalamus (PVT) was demonstrated in rodents and shown to be essential in the formation of threat memory
