Emotions are related to memory, thus they initiate responses which are timely (i.e. Fear to induce fast response) Within the CNS: The Cerebral Cortex • Frontal, Temporal, Parietal and Occipital lobes Two types of cells: • • Glia - supporting cells • Neurons (different types) • About 100 billion neurons in the brain (!!!)
