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 ...
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus; paratenial nucleus (nucleus parataenialis) nucleus reuniens (also known as the ...
Instead it modulates the information from other nuclei in the thalamus. Its function is modulatory on signals going through the thalamus (and the reticular nucleus). The thalamic reticular nucleus receives massive projections from the external segment of the globus pallidus , thought to play a part in disinhibition of thalamic cells, which is ...
The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [2]
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] midline nuclear group [8] or paramedian paratenial nucleus [9] paraventricular ...
As a group they make up the collection called the pulvinar of the thalamus (pulvinar thalami), usually just called the pulvinar. The pulvinar is usually grouped as one of the lateral thalamic nuclei in rodents and carnivores, and stands as an independent complex in primates.
The connections of the medial dorsal nucleus have even been used to delineate the prefrontal cortex of the Göttingen minipig brain. [ 7 ] By stereology the number of brain cells in the region has been estimated at around 6.43 million neurons in the adult human brain and 36.3 million glial cells , with the newborn having quite different numbers ...
