Fig. 1.3 Cerebral cortex organized into hair-thin columns
neural fibers that facilitates general interhemispheric communication. It is the
largest white matter structure in the brain, consisting of 200-250 million axons.
Note that the cerebrum in the forebrain refers to the combined right and left
hemispheres. Again, each hemisphere is divided into four lobes: three in back to
receive and analyze incoming sensory information and a frontal lobe to construct a
response.
Anterior Commissure
The anterior commissure is a separate bundle to connect the two amygdala and aids
in signaling sharp pain, olfaction, instinct, and sexual behavior.
Aside from redundancy for reliability, the right brain is geared to novel
challenges, for instance strange faces and new language. The left brain is geared
