  2. Lobes of the brain - Wikipedia

    en.wikipedia.org/wiki/Lobes_of_the_brain

    The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.

  3. Sulcus (neuroanatomy) - Wikipedia

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

    The sulci and fissures are shallow and deep grooves respectively in the cortex. 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] Fissures are the most prominent and invariable of the sulci. [2]

  4. Frontal lobe - Wikipedia

    en.wikipedia.org/wiki/Frontal_lobe

    The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal 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 ...

  5. Cerebrum - Wikipedia

    en.wikipedia.org/wiki/Cerebrum

    The lobes are classified based on their overlying neurocranial bones. [4] A smaller lobe is the insular lobe, a part of the cerebral cortex folded deep within the lateral sulcus that separates the temporal lobe from the parietal and frontal lobes, is located within each hemisphere of the mammalian brain.

  6. Central sulcus - Wikipedia

    The lateral surface of the right cerebral hemisphere. The central sulcus is labeled on the top center, in red. The central sulcus separates the parietal lobe (blue) and the frontal lobe (lime green).

  7. Lateral sulcus - Wikipedia

    en.wikipedia.org/wiki/Lateral_sulcus

    The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral ...

  8. Cerebral cortex - Wikipedia

    en.wikipedia.org/wiki/Cerebral_cortex

    The major sulci and gyri mark the divisions of the cerebrum into the lobes of the brain. The four major lobes are the frontal, parietal, occipital and temporal lobes. Other lobes are the limbic lobe, and the insular cortex often referred to as the insular lobe. There are between 14 and 16 billion neurons in the human cerebral cortex. [2]

  9. Cerebral hemisphere - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hemisphere

    Each cerebral hemisphere has an outer layer of cerebral cortex which is of grey matter and in the interior of the cerebral hemispheres is an inner layer or core of white matter known as the centrum semiovale. [3] The interior portion of the hemispheres of the cerebrum includes the lateral ventricles, the basal ganglia, and the white matter. [4]
