The thalamus has multiple functions, and is generally believed to act as a relay station, or hub, relaying information between different subcortical areas and the cerebral cortex. [29] In particular, every sensory system (with the exception of the olfactory system ) includes a thalamic nucleus that receives sensory signals and sends them to the ...
This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4]) medial nuclear group (medial dorsal nucleus, [5] a.k.a. dorsomedial) parvocellular part [6] (a.k.a. parvicellular part) magnocellular part [7]
The striatum is organized on a rostro-caudal axis, with the rostral putamen and caudate serving associative and cognitive functions and the caudal areas serving sensorimotor function. [6] Sometimes when the striatum is the expressed target the loop is referred to as the cortico-striatal-thalamic-cortical loop. [7]
The thalamus supplies all parts of the neocortex with afferents. [3] The main thalamocortical fibers extend from different nuclei of the thalamus and project to the visual cortex, somatosensory (and associated sensori-motor) cortex, and the auditory cortex in the brain. Thalamocortical radiations also innervate gustatory and olfactory pathways ...
The thalamic reticular nucleus is part of the ventral thalamus that forms a capsule around the thalamus laterally. However, recent evidence from mice and fish question this statement and define it as a dorsal thalamic structure. [1] [2] It is separated from the thalamus by the external medullary lamina.
The thalamus is generally believed to relay sensory information between a variety of subcortical areas and the cerebral cortex. [4] It is known that sensory information from environmental stimuli travels to the thalamus for processing and then to the somatosensory cortex for interpretation. The final product of this communication is the ability ...
In humans it makes up roughly 40% of the thalamus making it the largest of its nuclei. [16] Significant research has been undertaken in the marmoset examining the role of the retinorecipient region of the inferior pulvinar (medial subdivision), which projects to visual cortical area MT, in the early development of MT and the dorsal stream, as ...
The ventrobasal complex (VB) is a relay nucleus of the thalamus for nociceptive stimuli received from nociceptive nerves. The VB consists of the ventral posteromedial nucleus (VPM) and the ventral posterolateral nucleus (VPL). In some species, the ventral posterolateral nucleus, pars caudalis is also a part of the VB.
