What is the 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 and ventral lateral nuclei?
The ventral lateral nucleus is involved in relaying cerebellar signals to the primary motor area and plays a role in fine motor control. 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 function of ventral posterior nucleus?
Functions in touch, body position, pain, temperature, itch, taste, and arousal.
What does the ventral posterior nucleus do?
It is lateral to another part of the somatosensory thalamus, the ventral posterior medial (VPM) nucleus. The VPL nucleus is concerned with somatosensory input from the body, whereas the VPM nucleus receives information concerning the head.
What does the lateral nucleus do?
The function of the ventral lateral nucleus is to target efferents including the motor cortex, premotor cortex, and supplementary motor cortex. Therefore, its function helps the coordination and planning of movement. It also plays a role in the learning of movement.
What is the 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 is the function of VPL?
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 is ventral posterior?
The ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain.
What is the function of lateral hypothalamic nucleus?
The lateral hypothalamus is known for regulating metabolism and food intake. This was discovered by studies involving the effect of lesions in the lateral hypothalamus, which leads to reduced food intake and maintenance of the newly achieved reduced weight in obese rats.
What does VPM nucleus do?
nucleus of the thalamus that receives sensory information from the face and head and projects to the somatosensory cortex.
Where is the ventral posterolateral nucleus?
the thalamus
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.
What does the ventral posterolateral nucleus do?
nucleus of the thalamus that receives sensory input from the medial lemniscus and spinothalamic tract and projects to the somatosensory cortex.
What is the lateral geniculate nucleus?
The lateral geniculate nucleus is a multilayered structure that receives input from both eyes to build a representation of the contralateral visual hemifield.
What is the dorsal lateral geniculate nucleus?
The dorsal lateral geniculate nucleus (dLGN) of the thalamus is the principal conduit for visual information from retina to visual cortex. Viewed initially as a simple relay, recent studies in the mouse reveal far greater complexity in the way input from the retina is combined, transmitted, and processed in dLGN.
