1.Lobes and Gyri 3. Midline Cortical Structures
Cerebral
● Frontal Lobe ● Cingulate gyrus
○ Precentral gyrus ● Corpus Callosum
○ Superior frontal gyri ○Rostrum, Genu, Body, Splenium
○ Middle frontal gyri ● Cuneus
○ Inferior frontal gyri ● Precuneus
Cortex
○ Broca’s area:
■Pars opercularis, Pars triangularis, Pars
orbitalis
● Parietal Lobe 4. Functional Areas
○ Postcentral gyrus ● Frontal lobe areas
○ Superior parietal lobule ○ Primary motor area
○ Inferior parietal lobule ○ Premotor area
■Supramarginal gyri ○ Supplementary motor area
■Angular gyri ○ Frontal eye field
● Temporal Lobe ○ Broca’s area
○ Superior temporal gyri ○ Prefrontal cortex
○ Middle temporal gyri ● Parietal Lobe areas
○ Inferior temporal gyri ○ Primary somatosensory cortex
○ Transverse temporal gyri ○ Somatosensory association area
○ Parahippocampal gyrus ○ Wernicke’s area/ Verbal association area
○ Fusiform gyrus ● Temporal lobe areas
○ Uncus ○ Auditory cortex
● Occipital Lobe ○ Auditory association cortex
○ Superior occipital gyrus ○ Wernicke's area
○ Middle occipital gyrus ○ Fusiform face area
○ Inferior occipital gyrus ● Occipital lobe areas
● Insular Lobe ○ Visual cortex
○ Anterior lobe (short gyri of insula) ○ Visual association cortex
○ Posterior lobe (long gyri of insula) ● Insular lobe areas
○ Gustatory cortex
2. Fissure and Sulci
● Median longitudinal fissure
● Lateral fissure/ sulcus
● Transverse fissure
● Central sulcus
● Parieto-occipital sulcus
○Preoccipital notch
● Intraparietal sulcus
● Calcarine sulcus
, Case study: Phineas Gage
Phineas P. Gage (1823-1860) was an american railroad
construction foreman in the 1900’s. One day while blasting rock to
clear the way to lay new railbed, he had an accident that would
forever change his life. He became distracted by other foremen
while packing explosive powder into the rock, and accidented
scraped the surround rock, creating a spark and igniting the
explosive powder. This sent the 1.25 inch, 13lb rod that he was
holding, through the left side of his face, in an upward direction,
exiting through his frontal bone.
