Notable gyri

  • Fornicate gyrus
    Fornicate gyrus

    The fornicate gyrus is a gyrus of the cerebral cortex, located on the medial surface adjacent to the corpus callosum. It is named for the fornix of brain, a tract of white matter that runs beneath its surface roughly in a loop, from the amygdala to the mamillary bodies....
  • Superior frontal gyrus
    Superior frontal gyrus

    The superior frontal gyrus makes up about one-third of the frontal lobe of the human brain brain. It is bounded laterally by the superior frontal sulcus....
    , lat. gyrus frontalis superior
  • Middle frontal gyrus
    Middle frontal gyrus

    The middle frontal gyrus makes up about one-third of the frontal lobe of the human brain. The middle frontal gyrus, like the inferior frontal gyrus and the superior frontal gyrus, is more of a region than a true gyrus....
    , lat. gyrus frontalis medius
  • Inferior frontal gyrus
    Inferior frontal gyrus

    The inferior frontal gyrus is a gyrus of the frontal lobe of the human brain. Its superior border is the inferior frontal sulcus, its inferior border the lateral sulcus, and its posterior border is the precentral sulcus....
    , lat. gyrus frontalis inferior with 3 parts: pars opercularis, pars triangularis, and pars orbitalis
  • Superior temporal gyrus
    Superior temporal gyrus

    A gyrus is a bump or ridge on the surface of the brain. The superior temporal gyrus is one of three gyri in the temporal lobe of the human brain....
    , lat. gyrus temporalis superior
Middle temporal gyrus, lat. gyrus temporalis medius

Inferior temporal gyrus, lat. gyrus temporalis inferior
  • Fusiform gyrus
    Fusiform gyrus

    The fusiform gyrus is part of the temporal lobe. It is also known as the occipitotemporal gyrus. Other sources have the fusiform gyrus above the occipitotemporal gyrus and underneath the parahippocampal gyrus....
    , lat. gyrus occipitotemporalis medius
  • Parahippocampal gyrus
    Parahippocampal gyrus

    The parahippocampal gyrus is a grey matter cerebral cortex region of the brain that surrounds the hippocampus. This region plays an important role in memory Encoding and retrieval....
    , lat. gyrus parahippocampalis
  • Transverse temporal gyrus
    Transverse temporal gyrus

    The transverse temporal gyri are found in the area of primary auditory cortex in the superior temporal gyrus of the human brain, occupying Brodmann areas 41 and 42....
Precentral gyrus, lat. gyrus praecentralis
  • Postcentral gyrus
    Postcentral gyrus

    The lateral postcentral gyrus is a prominent structure in the parietal lobe of the human brain and an important landmark. It was initially defined from surface stimulation studies of Penfield, and parallel surface potential studies of Bard, Woolsey, and Marshall....
    , lat. gyrus postcentralis
Supramarginal gyrus, lat. gyrus supramarginalis

Angular gyrus, lat. gyrus angularis
  • Cingulate gyrus
    Cingulate gyrus

    Cingulate gyrus is a gyrus in the medial part of the brain. It partially wraps around the corpus callosum and is limited above by the cingulate sulcus....
     lat. gyrus cinguli
  • Dentate gyrus
    Dentate gyrus

    The dentate gyrus is part of the hippocampal formation. It is thought to contribute to new memory as well as other functional roles. It is notable as being one of a select few brain structures currently known to have high rates of neurogenesis in adult humans, ....
