  2. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    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.

  3. Cannon–Bard theory - Wikipedia

    en.wikipedia.org/wiki/Cannon–Bard_theory

    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 ...

  4. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    This processed information is often relayed to a collection of structures from the telencephalon, diencephalon, and mesencephalon, including the prefrontal cortex, cingulate gyrus, limbic thalamus, hippocampus including the parahippocampal gyrus and subiculum, nucleus accumbens (limbic striatum), anterior hypothalamus, ventral tegmental area ...

  5. Sensory gating - Wikipedia

    en.wikipedia.org/wiki/Sensory_gating

    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 ...

  6. Lateral hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Lateral_hypothalamus

    The lateral hypothalamus (LH), also called the lateral hypothalamic area (LHA), [1] contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; [2] this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature ...

  7. Ventromedial nucleus of the hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Ventromedial_nucleus_of...

    The ventromedial nucleus of the hypothalamus (VMN, VMH or ventromedial hypothalamus) is a nucleus of the hypothalamus.In 2007, Kurrasch et al. found that the ventromedial hypothalamus is a distinct morphological nucleus involved in terminating hunger, fear, thermoregulation, and sexual activity. [1]

  8. Contralateral brain - Wikipedia

    en.wikipedia.org/wiki/Contralateral_brain

    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 ...

  9. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the diencephalon is included in the brainstem. [ 2 ] The brainstem is very small, making up around only 2.6 percent of the brain's total weight. [ 3 ]
