  1. 1. Emotions
  2. 2. What are Emotions? • Emotions are burst of psychological arousal. • They are feelings associated with mood, temperament, personality, disposition, an d motivation. • They’re formed when numerous regions of the brain work together.
  3. 3. The Limbic System • The limbic system is a ring of structures are the brainstem. • These structures interact with sensory areas of the neocortex and other higher brain centers, mediating primary emotions that manifest emotional responses such as crying or laughing. • It attaches emotional feelings to basic survivalrelated functions such as aggression, feeding, and sexuality.
  4. 4. Structures of the Limbic System • • • • • • Amygdala Cingulate Gyrus Hypocampus Hypothalamus Olfactory cortex Thalamus Related Structures • cingulate gyrus • ventral tegmental area
  5. 5. Emotional Memory System • Uses both hippocampus and amygdala • Adults remember both image and arousal when faced with aversive situation • Electric shock- increase of heart rate when put in situation that mediates previous shocks • Hippocampus damage: do NOT remember situation, arousal STILL occurs due to amygdala. Also works vice-vera.

  8. 8. The Story of Phineas Gage • Efficient, capable, worker working on railroad construction site in 1848. • BOOM! Dynamite explosion drives meter-long iron through his head. Entered below left eye and exited through top of his head. • Destroys part of frontal lobe, but he recovers. • Now “impatient, profane and capricious.”
  9. 9. The Story of Phineas Gage • Skull examined in 1990s by nueroscientists. • Discovered the Frontal Lobe was used to mediate emotions. • In past, “Frontal Lobotomy” was used to treat emotional disorders by severing connection between frontal lobe and limbic system • Discovery showed Frontal Lobe is necessary to keep motivation, foresight, decision making intact.
