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.
Where is ventral lateral nucleus of thalamus?
The ventral lateral nucleus (VL) is a nucleus in the ventral nuclear group of the thalamus.
What is ventral anterior?
Directional Terms Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body).
What is ventral thalamus?
Definition. The ventral thalamus, as usually defined in the adult brain, consists of the reticular nucleus, the zona incerta, and the ventral lateral geniculate nucleus (Fig. 15.1). To this, many authors add the nucleus of the fields of Fore!’
What does the anterior nuclei of the thalamus do?
The anterior nuclei of the thalamus display functions pertaining to memory. Persons displaying lesions in the anterior thalamus, preventing input from the pathway involving the hippocampus, mammillary bodies and the MTT, display forms of amnesia, supporting the anterior thalamus’s involvement in episodic memory.
Where is the ventral anterior nucleus?
Ventral anterior nucleus It consists of two parts; a principal part and a magnocellular part. The ventral anterior nucleus is located on the path between the basal ganglia and the motor areas of the premotor cortex, relaying information from both.
What does ventral mean in medical terms?
Medical Definition of ventral 1 : of or relating to the belly : abdominal. 2a : being or located near, on, or toward the lower surface of an animal (as a quadruped) opposite the back or dorsal surface. b : being or located near, on, or toward the front or anterior part of the human body.
What are thalamic nuclei?
The thalamus is a paired structure located in the center of the brain. Each side can divide into three groups of thalamic nuclei: a lateral nuclear group, a medial nuclear group, and an anterior nuclear group.
What is the ventral posterior nucleus?
The ventral posterior nucleus, sometimes called the ventrobasal complex, is a wedge-shaped cell group located caudally in the thalamus. Its lateral border abuts the internal capsule, and ventrally it borders on the external medullary lamina.
