3.4 Flashcards
Forebrain
The most rostral of the three
major divisions of the brain; includes the
telencephalon and diencephalon
Cerebral Hemisphere
One
of the two major portions of the forebrain,
covered by the cerebral cortex
Cerebrum
Consists of the two cerebral hemispheres
Subcortical region
The region located
within the brain, beneath the cortical
surface
Sulcus
A groove in the surface of the
cerebral hemisphere, smaller than a
fissure
Fissure
A major groove in the surface of the brain, larger than a sulcus
Gyrus
A convolution of the cortex of the cerebral
hemispheres, separated by sulci or fissures.
Frontal lobe
The anterior portion of the
cerebral cortex, rostral to the parietal lobe
and dorsal to the temporal lobe.
Parietal lobe
The region
of the cerebral cortex caudal to the frontal
lobe and dorsal to the temporal lobe
temporal lobe
The region
of the cerebral cortex rostral to the
occipital lobe and ventral to the parietal
and frontal lobes.
Occipital lobe
The region
of the cerebral cortex caudal to the
parietal and temporal lobes.
Primary visual cortex
The region of the
posterior occipital lobe whose primary
input is from the visual system.
Calcarine fissure
A fissure
located in the occipital lobe on the medial
surface of the brain; most of the primary
visual cortex is located along its upper and
lower banks
Primary auditory cortex
The region of
the superior temporal lobe whose primary
input is from the auditory system
Lateral fissure
The fissure that separates
the temporal lobe from the overlying
frontal and parietal lobes.
