Functional Brain Systems Networks of neurons working together and spanning wide areas of the brain The two systems are: Limbic system Reticular formation

Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Limbic System - Structures located on the medial aspects of cerebral hemispheres and diencephalon - Includes the rhinencephalon, amygdala, hypothalamus, and anterior nucleus of the thalamus - Parts especially important in emotions: Amygdala – deals with anger, danger, and fear responses Cingulate gyrus – plays a role in expressing emotions via gestures, and resolves mental conflict - Puts emotional responses to odors – e.g., skunks smell bad

Limbic System: Emotion and Cognition - The limbic system interacts with the prefrontal lobes, therefore: One can react emotionally to conscious understandings One is consciously aware of emotion in one ’ s life - Hippocampal structures – convert new information into long-term memories
