  1. General function of Frontal Lobe
    Consists of higher-order heteromodal association cortex (Mostly prefrontal cortex). The frontal lobe is important in restraining behaviors, initiative, order & sequence.
  2. Function of Broca’s Area
    Region of speech production in dominant hemisphere (95% right-handers and 70% left-handers).
  3. Frontal Sulci
    Superior and Inferior; divide the 3 frontal gyri.
  4. Motor Homunculus
    Located in the Precentral Gyrus; it represents body regions in the Primary Motor cortex; point of origin of the corticospinal tract
  5. Central Sulcus
    Separates pre- from post-central gyrus.
  6. General function of Temporal Lobe
    Auditory perception, language perception; plays a key role in the formation of long-term memories (via the hippocampus).
  7. Function of Lateral Sulcus
    It separates the frontal and parietal lobes from the temporal lobe.
  8. Function of Wernicke’s Area
    Comprehension of language in the dominant hemisphere; it encircles the primary auditory cortex.
  9. Function of Primary Auditory Cortex
    Process auditory input, including volume and pitch.
  10. Function of the Insula
    It is the interoceptive center; regulation of emotions, autonomic, motor and sensory processing.
  11. General Function of the Parietal Lobe
    It integrates sensory information, including modalities that determine spatial relationships.
  12. Function of the Somatosensory Cortex
    The sensory homunculus is present in the postcentral gyrus (Brodmann areas 3, 1 and 2).
  13. Postcentral sulcus
    Posterior to the Post-central gyrus.
  14. Intraparietal sulcus
    Horizontal and Oblique portions; cortical areas surrounding it are involved in numerical, spatial and symbols perception.
  15. General Function of the Occipital Lobe and Visual Cortex
    Processing of visual input, including color, frequency of electromagnetic waves, and spatial relationships.
  16. Function of the Corpus Callosum
    Largest cerebral commissural fiber bundle; interconnects the cerebral hemispheres.
  17. Function of the Cingulate Gyrus
    Involved in Limbic circuitries (including Papez).
  18. Paracentral gyri
    Supplementary motor area (involve in motor planning).
  19. Marginal Sulcus
    Separates the paracentral gyri from the Precuneus.
  20. Precuneus
    Regulates visuospatial imagery; episodic memory; visual imagery of self.
  21. Parieto-Occipital sulcus
    Separates the Parietal and Occipital Lobes.
  22. Cuneus
    Provides with basic visual processing.
  23. Calcarine Sulcus
    Primary visual cortex location.
  24. Straight Gyrus
    Part of the frontal lobe; function is unclear.
  25. Olfactory Sulcus
    Groove occupied by Olfactory Nerve.
  26. Olfactory Nerve
    C.N. I. Provides olfaction; purely sensory.
  27. Optic Nerve
    C.N. II. Conveys visual input; purely sensory. Nasal fibers of C.N.II decussate at the chiasm, and becomes the optic tract.
  28. Orbital Gyri
    • Associated with vagal processing.
    • Inferior Temporal Gyrus: Involved in complex visual processing.
  29. Occipitotemporal gyri
    Involved in visual processing; recognition of face and body.
  30. Parahippocampal Gyrus
    Processing of visual background and scenery.
  31. Uncus
    Anterior flexure of the Parahippocampal gyrus. Point of origin of seizures with olfactory hallucinations.
  32. Perforated Substances
    Gray matter with multiple openings for arteries supplying internal capsule and other structures.
