The principal subdivision of the thalamus into nucleus groups is the trisection of each thalamus (left and right) by a Y-shaped internal medullary lamina. This trisection divides each thalamus into anterior, medial and lateral groups of nuclei. [8] The medial group is subdivided into the medial dorsal nucleus and midline group.
The main concepts of the Cannon–Bard theory are that emotional expression results from the function of hypothalamic structures, and emotional feeling results from stimulations of the dorsal thalamus. The physiological changes and subjective feeling of an emotion in response to a stimulus are separate and independent; arousal does not have to ...
The contralateral organization of the forebrain (Latin: contra‚ against; latus‚ side; lateral‚ sided) is the property that the hemispheres of the cerebrum and the thalamus represent mainly the contralateral side of the body. Consequently, the left side of the forebrain mostly represents the right side of the body, and the right side of ...
The pulvinar nuclei of the thalamus plays a major role in attention, and has a major role in filtering out unnecessary information in regards to sensory gating. In a proven clinical study, it has been found out that the two stimuli (S1 and S2) are transported within 500ms between the clicks and 8 seconds between the pairs, in which S1 is known ...
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.
A Rotating View of the Thalamus. It is known that the thalamus plays a crucial role in memory. [18] While investigating stroke-patients with damage to the thalamus, Cipolotti et al. (2008) [19] found that the stroke victims had poor recognition and recall memory on verbal and non-verbal tests. The poor recall identified that the retrospective ...
The anterior cingulate cortex receives primarily its afferent axons from the intralaminar and midline thalamic nuclei (see thalamus). The nucleus anterior receives mamillo-thalamic afferences. The mamillary neurons receive axons from the subiculum. The whole forms a neural circuit in the limbic system known as the Papez circuit. [9]
Beneath the lateral ventricles is the thalamus and to the front and below is the hypothalamus. The hypothalamus leads on to the pituitary gland. At the back of the thalamus is the brainstem. [27] The basal ganglia, also called basal nuclei, are a set of structures deep within the hemispheres involved in behaviour and movement regulation. [28]
