What is the function of ventral lateral nucleus?
Table of Contents
What is the function of ventral lateral nucleus?
The ventral lateral nucleus of the thalamus (VL) serves as a central integrative center for motor control, receiving inputs from the cerebellum, striatum, and cortex and projecting to the primary motor cortex.
What is the function of the ventral anterior thalamic nucleus?
The ventral anterior nucleus is involved in relaying the basal ganglia signals to the premotor cortex and plays a role in planning and initiating movements.
What is the ventral intermediate thalamic nucleus?
Posterior part of VL (VLp), also called the Ventral intermediate nucleus (Vim) of the thalamus. The relay nucleus of the thalamus for the cerebellum, receiving input from the opposite cerebellum via the superior cerebellar peduncle.
Which part of thalamus is related to motor control?
Motor thalamus (Mthal) is implicated in the control of movement because it is strategically located between motor areas of the cerebral cortex and motor-related subcortical structures, such as the cerebellum and basal ganglia (BG).
What is the intermediate mass of the thalamus?
The interthalamic adhesion (also known as the intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.
What are VPL and VPM of thalamus?
The VPL and VPM are the primary thalamic relays for somatic sensory, i.e., nociceptive and tactile/kinestetic, information from the body and the head, respectively. For a comprehensive treatment of the pain system and the role of the thalamus in transmitting and modulating pain signals, see Chapter 27 by Willis et al.
What are the different 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.
Where is the vim in the brain?
The VIM is centrally placed on a cerebello-thalamo-cortical network in which pathological oscillations, possibly triggered by pallidal dysfunction in the case of PD, is thought to be culpable for tremor (Helmich et al., 2011).
Where is ventrolateral nucleus?
the thalamus
The ventral lateral nucleus (VL) is a nucleus in the ventral nuclear group of the thalamus.
Why thalamus is called relay Centre?
Thalamus is known as the relay center because it performs relaying of motor and sensory signals to the cerebral cortex.
Does everyone have Massa Intermedia?
Massa intermedia (MI) is an inconsistent midline structure in the human brain that is absent in approximately 30% of the population. Absence of MI is seen more frequently in schizophrenia spectrum disorder and bipolar disorder. However, very little is known about the normal role of MI in the human brain.
What is VPM in thalamus?
nucleus of the thalamus that receives sensory information from the face and head and projects to the somatosensory cortex.
What are VPL synapses?
In primates, the VPL nucleus receives synaptic input from both the dorsal column-medial lemniscus pathway, spino-cervicothalamic pathway and the spinothalamic tract.
What does VIM thalamus do?
The Vim is the thalamic relay of the CTC; it sends projections primarily to the motor cortex (area 4). This pathway is important for movement control and, thus, has been one of the targets for tremor reduction in patients with Parkinson disease.
