a. frontal lobe
b. parietal lobe
c. occipital lobe
d. temporal lobe
a. parietal lobe
b. limbic lobe: on edge of lateral ventricle, beneath what we can see of limbic lobe
c. frontal lobe
d. temporal lobe
e. occipital lobe
a. central sulcus- upward at angle from lateral sulcus; extends a bit to medial surface
b. lateral sulcus: groove between temporal and frontal lobes and temporal/parietal lobe
c. pre-occipital notch: helps to know where temporal stops and occipital starts
a. superior frontal gyri
b. middle frontal gyri
c. inferior frontal gyri
d. precentral gyrus- primary motor cortex; motor instructructions programmed here
a. postcentral gyrus- important because sensory region in cerebral hemisphere
b. superior parietal lobule
c. supramarginal gyrus- we could follow lateral sulcus up and it would dead end here
d. inferior parietal lobule- if damaged on R side, person will ignore left side of world= lateral neglect
e. angular gyrus- superior temporal sulcus dead ends here
f. cingulate gyrus: not just in parietal lobe, a lot of times just lumped into limbic lobe
a. superior temporal gyri (much auditory processing here)
b. middle temporal gyri
c. inferior temporal gyri
d. parahippocampal gyrus (structures inside bulge like hippocampus)
a. olfactory bulb
b. olfactory tract
