Thalamus rhythm
Web2 Mar 2024 · The thalamus is a neural processor and integrator for the activities of the forebrain. Surprisingly, little is known about the roles of the “cerebellar” thalamus despite the anatomical observation that all the cortico-cerebello-cortical loops make relay in the main subnuclei of the thalamus. The thalamus displays a broad range of electrophysiological … Web13 Jan 2024 · It depends for the most part on a balance between the intrinsic, basal polarity of thalamocortical neurons, and the effect of synchronising, inhibitory input from the reticular nucleus. The latter is in turn subject to cortical feedback. There are huge numbers of neurons involved.
