Document Summary
Module 6: the cerebral cortex and our divided brain. Neural networks within the cerebrum form specialized work teams that enable our perceiving, thinking and speaking. Like other structures above the brainstem (including the thalamus, interconnected neural cells hippocampus, and amygdala), the cerebral hemispheres come as a pair. Covering those hemispheres is the cerebral cortex, a thin surface layer of: it is your brains thinking crown, your body"s ultimate control and information-processing center. The brain is a wrinkled organ, without these wrinkles, a flattened cerebral cortex would require triple the area cells and 300 trillion synaptic connections. The cerebral cortex (thin surface layer) contains some 20-23 billion nerve. Supporting these billion of nerve cells are nine times as many glial cells. The brain"s left and right hemispheres are filled mainly with axons connecting the cortex to the brain"s other regions (cid:498)glue cells(cid:499)
