  2. Insular cortex - Wikipedia

    en.wikipedia.org/wiki/Insular_cortex

    The insular cortex is divided by the central sulcus of the insula, into two parts: the anterior insula and the posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid ).

  3. Salience network - Wikipedia

    en.wikipedia.org/wiki/Salience_network

    The salience network is theorized to mediate switching between the default mode network and central executive network. [1] [2]The salience network (SN), also known anatomically as the midcingulo-insular network (M-CIN) or ventral attention network, is a large scale network of the human brain that is primarily composed of the anterior insula (AI) and dorsal anterior cingulate cortex (dACC).

  4. Frontal lobe injury - Wikipedia

    en.wikipedia.org/wiki/Frontal_lobe_injury

    A single test, such as the WCST, cannot be used to measure the effects of a frontal lobe injury, or the aspects of cognitive function it may affect, such as working memory; variety of tests must be used. A subject may be good at one task but show dysfunction in executive function overall. Similarly, test results can be made misleading after ...

  5. Operculum (brain) - Wikipedia

    en.wikipedia.org/wiki/Operculum_(brain)

    Normally, the insular opercula begin to develop between the 20th and the 22nd weeks of pregnancy. At weeks 14 to 16 of fetal development, the insula begins to invaginate from the surface of the immature cerebrum of the brain, until at full term, the opercula completely cover the insula. [4] This process is called opercularization. [5]

  7. Interoception - Wikipedia

    en.wikipedia.org/wiki/Interoception

    The insula is considered to be a "hub" region because it has an extremely high number of connections with other brain areas, suggesting it may be important for an integration of lower-level physiological information and salience. [52] The insula connects to many regions in the brain and is highly involved in many homeostatic functions.

  8. Primary sensory areas - Wikipedia

    en.wikipedia.org/wiki/Primary_sensory_areas

    Taste: The primary gustatory area consists of the anterior part of the insula and the frontal operculum. [2] [3] [4] Olfaction: The olfactory cortex is located in the uncus which is found along the ventral surface of the temporal lobe. Olfaction is the only sensory system that is not routed through the thalamus.

  9. Brodmann area 25 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_25

    This region is extremely rich in serotonin transporters and is considered as a governor for a vast network involving areas like hypothalamus and brain stem, which influences changes in appetite and sleep; the amygdala and insula, which affect the mood and anxiety; the hippocampus, which plays an important role in memory formation; and some parts of the frontal cortex responsible for self ...
