  2. Sulcus (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Sulcus_(neuroanatomy)

    The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. [2] A sulcus is a shallow groove that surrounds a gyrus or part of a gyrus. A fissure is a deeper furrow that divides the brain into lobes, and also into the two hemispheres as the longitudinal fissure. [4]

  3. Sulcus (morphology) - Wikipedia

    en.wikipedia.org/wiki/Sulcus_(morphology)

    Occipitoparietal fissure: found between the occipital and parietal lobes of the brain. Wernicke's fissure: separates the brain's temporal and parietal lobes from the occipital lobe. Zygal fissure: found in the cerebrum. In the brain, a sulcus is a groove formed in the stage of gyrification by the folding of the cortex.

  4. Neural groove - Wikipedia

    en.wikipedia.org/wiki/Neural_groove

    The neural groove is a shallow median groove of the neural plate between the neural folds of an embryo. The neural plate is a thick sheet of ectoderm surrounded on either side by the neural folds, two longitudinal ridges in front of the primitive streak of the developing embryo.

  5. Gyrification - Wikipedia

    en.wikipedia.org/wiki/Gyrification

    Gyrification in the human brain. Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci).

  6. Central sulcus - Wikipedia

    en.wikipedia.org/wiki/Central_sulcus

    In neuroanatomy, the central sulcus (also central fissure, fissure of Rolando, or Rolandic fissure, after Luigi Rolando) is a sulcus, or groove, in the cerebral cortex in the brains of vertebrates. It is sometimes confused with the longitudinal fissure.

  7. Frontal lobe - Wikipedia

    en.wikipedia.org/wiki/Frontal_lobe

    It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral sulcus (Sylvian fissure). The most anterior rounded part of the frontal lobe (though not well-defined) is known as the frontal pole, one of the three poles of the cerebrum. [1]

    Scrolling on social media is also a way to "disassociate" and give the brain a rest after a long day, Bobinet said. This is an "avoidance behavior," which the habenula controls.

  9. Gyrus - Wikipedia

    en.wikipedia.org/wiki/Gyrus

    Pachygyria is used to describe brain characteristics in association with several neuronal migration disorders; most commonly relating to lissencephaly. Lissencephaly ( smooth brain ) is a rare congenital brain malformation caused by defective neuronal migration during the 12th to 24th weeks of fetal gestation resulting in a lack of development ...
