Striatum et thalamus
WebHowever, these neurons also receive substantial GABAergic input from two sources: the globus pallidus and the reticular nucleus of the thalamus. How ethanol modulates inhibitory input onto fast-spiking neurons is unclear and, more broadly, alcohol effects on GABAergic synaptic transmission onto GABAergic interneurons are understudied. WebThe thalamus is a centrally located subcortical region that is divided up into multiple nuclei, some of which receive basal ganglia input, and almost all of which have extensive, segregated and well-organized connections to the cortex ( Halassa, 2011; Nakajima and Halassa, 2024; Rikhye et al., 2024b ).
