  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). The opercula are formed from parts of the ...

  3. Lobes of the brain - Wikipedia

    en.wikipedia.org/wiki/Lobes_of_the_brain

    The insular cortex is divided into two parts: the larger anterior insula and the smaller 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). The opercula are formed from parts of the enclosing frontal ...

  4. Brodmann area 13 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_13

    These areas are differentiated from the more anterior area 11 by a lack of continuous granular layer, [2] and from the more posterior agranular Insular cortex. [3] Area 13b is a thin and dysgranular cortical area, often characterized by crossing patterns of striations in layers III and V. Area 13a has an agranular structure.

  5. Operculum (brain) - Wikipedia

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

    The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus. It sits like an island (the meaning of insular ) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.

  6. Posterior cingulate cortex - Wikipedia

    en.wikipedia.org/wiki/Posterior_cingulate_cortex

    The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the "limbic lobe". The cingulate cortex is made up of an area around the midline of the brain. Surrounding areas include the retrosplenial cortex and the precuneus.

  7. Default mode network - Wikipedia

    en.wikipedia.org/wiki/Default_mode_network

    In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.

  8. Cingulate cortex - Wikipedia

    en.wikipedia.org/wiki/Cingulate_cortex

    The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus. The cingulate cortex is usually considered part of the limbic lobe.

  9. Inferior frontal gyrus - Wikipedia

    en.wikipedia.org/wiki/Inferior_frontal_gyrus

    Opercular part of inferior frontal gyrus (pars opercularis), (cortex posterior to the ascending ramus of the lateral sulcus), is the part of frontal lobe that overlies the insular cortex and may be associated with recognizing a tone of voice in spoken native languages. [6]
