What are the nuclei of the thalamus?

Each side can divide into three groups of thalamic nuclei: a lateral nuclear group, a medial nuclear group, and an anterior nuclear group. These three groups get split by the internal medullary lamina, a Y-shaped structure present on each side of the thalamus.

What is intralaminar nuclei of thalamus?

The intralaminar thalamic nuclei (ITN) are collections of neurons in the thalamus that are generally divided in two groups as follows: anterior (rostral) group. central medial nucleus. paracentral nucleus. central lateral nucleus.

What is the diagonal band of Broca?

The diagonal band of Broca is one of the basal forebrain structures that are derived from the ventral telencephalon during development. This structure forms the medial margin of the anterior perforated substance. This brain region was described by the French neuroanatomist Paul Broca. Base of brain.

What are the thalamic nuclei for each sensory system?

Each sensory function has a thalamic nucleus that receives, processes and transmits the information to its related area within your cerebral cortex. Relaying motor (movement) information. Similar to sensory information, motor pathways all pass through your thalamus. Prioritizing attention.

What are pulvinar nuclei?

The pulvinar is the largest nucleus of the thalamus and has strong connectivity with the visual cortex. The pulvinar is a prototypic association nucleus that participates in reciprocal cortico-cortical interactions and promotes synchronized oscillatory activity in functionally related areas of the cortex.

What is the medial septum diagonal band?

The medial septal-diagonal band of Broca (MSDB) is an important modulator of hippocampal function. The MSDB influences the hippocampus through projections from cholinergic, GABAergic, and glutamatergic neurons (Amaral and Kurz, 1985; Freund, 1989; Manseau et al., 2005).

What is the nucleus basalis of meynert?

Abstract. The nucleus basalis of Meynert (nbM) was first described at the end of the 19th century and named after its discoverer, Theodor Meynert. The nbM contains a large population of cholinergic neurons that project their axons to the entire cortical mantle, the olfactory tubercle, and the amygdala.

Which thalamic nuclei is the relay for the trigeminal system?

The more caudally lying ventroposterior lateral (VPL) nucleus is the main somatosensory relay nucleus for the body with input from the dorsal column nuclei, and a nucleus medial to it, the ventroposterior medial nucleus (VPM), serves the same function for the trigeminal system from the head.

What is pulvinar in thalamus?

What is the role of the pulvinar?

The pulvinar is the posterior nuclear complex in the thalamus most frequently associated with processing of visual information. It is considered to be important in two aspects of transmission of information, from layer 5 of one cortical area to another, and in integrating multisensory information.
