The image shows dopaminergic pathways of the human brain in normal condition (left) and Parkinsons Disease (right). Red Arrows indicate suppression of the target, blue arrows indicate stimulation of target structure. (Thalamic fasciculus visible but not labeled, as red line from GPi to THA.)
|Anatomical terms of neuroanatomy|
The thalamic fasciculus is a component of the subthalamus. It is synonymous with field H1 of Forel. Nerve fibres form a composite bundle containing cerebellothalamic (crossed) and pallidothalamic (uncrossed) fibres that is insinuated between the thalamus and zona incerta.
The thalamic fasciculus consists of the joint fibers of the ansa lenticularis and the lenticular fasciculus, coming from different portions of the medial globus pallidus, before they jointly enter the ventral anterior nucleus of the thalamus.
