accessory nuclei of optic tract

[TA]
small groups of neuron cell bodies located along the trajectory of optic fibers in the mesencephalon. These consist of the posterior nucleus [TA] (nucleus posterior [TA]), medial nucleus [TA] (nucleus medialis [TA]), and lateral nucleus [TA] (nucleus lateralis [TA]), which are also called the posterior, medial, and lateral terminal nuclei. The connections of these nuclei, along with the nucleus of the optic tract, make up the accessory optic system that appears to be concerned with retinal slip in specific directions.

The sensory thalamic cluster (red) included the lateral nucleus and the ventral posterior and the ventral lateral thalamic nuclei projecting to posterior parietal and postcentral cortical areas.
[7], 2010 HH immediately disappeared Current case, 2017 Persistent HH in off stimulation GPi: globus pallidus internus; HH: hemichorea/hemiballism; mo: months; VL: ventral lateral nucleus; VO: ventralis oralis; Voa: ventralis oralis anterior; Vop: ventralis oralis posterior.
While linguistic disorders-in which repetition is preserved and speech output is diminished and that anomia and paraphasias accompany-are attributed to ventrolateral and ventral anterior nuclei lesions, a fluent aphasia is seen with pulvinar and posterior lateral nucleus lesions.
One large piece is formed by fusion of upper pair nuclei, medial nuclei of middle pair and left lateral nucleus of middle pair.
These motor-related brain regions included the bilateral declive, bilateral culmen, bilateral inferior frontal cortex, bilateral inferior parietal lobule, lateral nucleus of thalamus, bilateral superior temporal cortex, bilateral middle temporal cortex, left precentral cortex, left postcentral cortex, right precentral cortex, right postcentral cortex, precuneus, bilateral insula, bilateral posterior thalamus, bilateral anterior cingulate cortex, bilateral caudate nucleus, bilateral middle cingulate cortex, and substantia nigra.
During motor task, the right postcentral gyrus and middle temporal gyrus served as the hubs of the network in healthy controls, receiving the most information inflows from cortical and subcortical brain regions, such as left precentral gyrus, precuneus, caudate nucleus, inferior parietal lobule, and lateral nucleus of thalamus.
In healthy controls, left precentral gyrus, left postcentral gyrus, and inferior parietal lobule served as the hubs of the network, but in stroke patients, the hubs of the network included left precentral gyrus, left postcentral gyrus, insula, culmen, and the lateral nucleus of thalamus.
activity was statistically significant between groups in the supramammillar nucleus (p < .05), the medial (p < .05), the medial lateral (p < .05) and lateral nucleus (p < .05).
Regarding the mammillary bodies, group differences were found in medial lateral nucleus, F(2, 41) = 238.160, p < .001, and the lateral nucleus, F(2, 42) = 33.523, p < .001.
The neurons here are densely stained and resemble those of the central lateral nucleus (CL).
Projections from the cerebellum are relayed to separate divisions of the ventral lateral nucleus, a major role of the cerebellum being to guide movements, once they have been initiated by the action of the direct loop and the suppression of the indirect loop by dopaminergic inputs to the dorsal striatum (Hoover and Strick, 1999; Middleton and Strick, 1998).
The lateral nucleus of the amygdala, in particular, receives ascending sensory projections.
