WebAug 9, 2016 · The thalamus constitutes the final subcortical link within the CSTC loop. When uncoupled from inhibitory striatal influence, thalamic projections exert excitatory effects on the cortex and thus are crucially involved in diverse cognitive and executive tasks, such as strategy selection, behavioral flexibility and prospective coding [ 54 ]. WebNov 22, 2024 · The thalamic reticular nucleus is a thin shell of GABAergic neurons surrounding the thalamus, projecting topographically to the same thalamic nucleus as the layer 6 cortico-thalamic fibers passing through it. In contrast to the layer 5 fibers, layer 6 fibers are thought to modulate the state of thalamic relay neurons.
