Thalamocortical radiationsIn neuroanatomy, thalamocortical radiations also known as thalamocortical fibres, are the efferent fibres that project from the thalamus to distinct areas of the cerebral cortex. They form fibre bundles that emerge from the lateral surface of the thalamus. Thalamocortical fibers (TC fibres) have been referred to as one of the two constituents of the isothalamus, the other being microneurons. Thalamocortical fibers have a bush or tree-like appearance as they extend into the internal capsule and project to the layers of the cortex.
Ganglions de la baseLes ganglions de la base (autrement appelés noyaux gris centraux ou noyaux de la base) sont un ensemble de structures sous-corticales constitué par des noyaux pairs, interconnectés au niveau télencéphalique (hémisphères cérébraux) et diencéphalique. Leur structure peut varier selon qu'on les définit de manière anatomique ou fonctionnelle.
