Frontal Lobe
The frontal lobe is of interest because of its presumed role in emotion, learning, and executive function. The olfactory bulb (#4965) and tract (#4963) are on the lobe's ventral surface. contains Broca's area
49
Parietal Cortex
primary cortical region for the sensations of touch and pressure and is commonly referred to as primary somatosensory (somesthetic) cortex. function in speech, reading, and the use of numbers (calculation).
50
Temporal Lobe
auditory cortex. is Wernicke's area, the sensory speech area. Lesions here produce receptive aphasia where patients cannot comprehend speech.
51
Telencephalon
cerebrum corpos callosum
52
diencephalon
whose major divisions are the thalamus (#7921, #4838), hypothalamus (#4270, #4848), epithalamus (pineal body) (#4839) and the subthalamus, which is deep to the surface and can only be seen on brain sections.
