Document Summary

Module 6 the cerebral cortex and our divided brain. Older brain networks sustain basic life functions and enable memory, emotion and basic drives. Newer neural networks in the cerebrum (hemisphere that contributes 85% of the brain"s weight) from specialized work teams that enable perceiving, thinking and speaking. Cerebral hemispheres come as a pair (like the thalamus, hippocampus and amygdala) These hemispheres are covered by the cerebral cortex. Cerebral cortex: intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body"s ultimate control and information-processing center. Larger cerebral cortex offers increased capacity for learning and thinking, and therefore better capacity for adaptation. The brain"s left and right hemispheres are filled with axons connecting the cortex to the brain"s other regions. The cerebral cortex contains 20-23 billion nerve cells and 300 trillion synaptic connections. These nerve cells are supported by glial cells.
