What does the VPL of the thalamus 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 ventrolateral thalamus?
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 ventral lateral nucleus?
Functions. 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 goes to VPM of thalamus?
nucleus of the thalamus that receives sensory information from the face and head and projects to the somatosensory cortex.
What is Neospinothalamic?
The neospinothalamic tract conducts fast pain (via A delta fibers) and provides information of the exact location of the noxious stimulus, and the multisynaptic paleospinothalamic and archispinothalamic tracts conduct slow pain (via C fibers), a pain which is poorly localized in nature. (
What are VPL and VPM of thalamus?
The VPL nucleus is a part of the somatosensory thalamus. 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.
Is the amygdala part of the basolateral complex?
The basolateral amygdala (BLA), or basolateral complex, consists of the lateral, basal and accessory-basal nuclei of the amygdala. The lateral nuclei receives the majority of sensory information, which arrives directly from the temporal lobe structures, including the hippocampus and primary auditory cortex.
What is the ventral intermediate thalamic nucleus?
The ventral intermediate nucleus (VIM) of the thalamus is an established surgical target for stereotactic ablation and deep brain stimulation (DBS) in the treatment of tremor in Parkinson’s disease (PD) and essential tremor (ET).
What is medial to the thalamus?
The medial surface of the thalamus constitutes the upper part of the lateral wall of the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic adhesion.
Which thalamic nucleus is most important for relaying somatosensory information from the face?
The ventral posterior nucleus is the main relay nucleus for the somatosensory pathways. It is subdivided into two parts: ventral posteromedial (or VPM) and ventral posterolateral (or VPL). This nucleus establishes several neuronal pathways with different regions within the brain.
Which special sense is associated with the ventral posterior nucleus of the thalamus?
The thalamus is also important for touch – the ventral posterior nuclei relay information regarding touch and perception of bodily position to the primary somatosensory cortex in the cerebral cortex. In addition, the thalamic nuclei are strongly and reciprocally linked with the cerebral cortex.
