Web23 Apr 2002 · Our observations in human brains show that during a short developmental period (g.w. 12–14) SERT-labeled fiber tracts are present in the same zones as the thalamocortical axons, i.e., in the internal capsule and the corona radiata. This suggests that the thalamocortical axons in humans may transiently express SERT, as they do in rodents. Web12 Apr 2024 · The thalamic nuclei are the clusters of densely packed neuronal cell bodies that comprise the thalamus. The thalamus is an ovoid, paired gray matter structure, found in the center of the brain, just superior to the brainstem.
