1 Duygular

2 Tepki Örüntüleri Olarak Duygular  Korku  Amygdala  Lateral Nucleus (LA) – şu yapılardan duyusal bilgiyi alır: Neokorteks, thalamus ve hippocampus – ve şu yapılara projeksiyonlar yapar: basal, accessory basal, ve amygdala merkez çekirdeği.  Central Nucleus – şu yapılardan bilgiyi alır: basal, lateral ve şu yapılara projeksiyonlar yapar: accessory basal nuclei ve duygularla ilgili bilgilerin işlendiği birçok beyin alanı.  Koşullu Duygusal Tepki – Klasik koşullu korku tepkisi.

5 Tepki Örüntüleri Olarak Duygular (devam)  Amygdala insanda duygusal tepkilerle ilişkilidir.  Amygdala lezyonları duygusal tepkilerde azalmaya yol açar.  Amygdala lezyonları koşullu duygusal tepkileri azaltır.  Amygdala lezyonları bellek üzerindeki duygu etkilerini etkiler..  Medial prefrontal corteks koşullu duygusal tepkilerin sönmesinde rol oynar.

6 Tepki Örüntüleri Olarak Duygular (devam)  Öfke, Saldırganlık ve Dürtü Kontrolü Davranış  Tehdit Davranışı– saldırma ihtimali bulunan başka bir hayvanı uyarmaya yönelik türe-özgü stereotipik davranış.  Savunma Davranışı – diğer bir hayvandan gelecek bir tehdite karşı kendisini korumak için bir hayvanın kullandığı türe-özgü davranış.  Boyun Eğme Davranışı – başka bir hayvandan gelen bir tehdit karşısında gösterilen stereotipik davranış.

8 Emotions as Response Patterns (Continued)  Role of Serotonin  Activity of serotonergic synapses inhibits aggression.  Destruction of serotonergic axons in the forebrain facilitates aggressive attack.  Ventromedial Prefrontal Cortex (vmPFC)  Includes medial orbitofrontal cortex and subgenual anterior cingulate cortex.  Plays a role in complex analyses of social situations.

10 Emotions as Response Patterns (Continued)  Hormonal Control of Aggressive Behavior  Aggression in Males  In rodents, androgen secretion occurs prenatally, decreases, and increases again at puberty.  Intermale aggressiveness increases at puberty.  Aggression in Females  Less aggressive than males.  Aggression appears to be facilitated by testosterone.

12 Communication of Emotions  Facial Expression of Emotions: Innate Responses  Facial expression of emotions appear to be innate.  Cross-cultural studies and studies of blind children support the belief that facial expressions of emotion are innate.

13 Communication of Emotions (Continued)  Neural Basis of the Communication of Emotions: Recognition  Laterality of Emotional Recognition  Right hemisphere is more important for the comprehension of emotion.  Role of the Amygdala  Important for emotion recognition, especially for facial expressions.  Affective Blindsight – ability of a person who cannot see objects in his/her blind field to accurately identify facial expressions of emotion without conscious perception of them.

14 Communication of Emotions (Continued)  Perception of Direction of Gaze  Recognition of the direction of another monkey’s gaze involves neurons in the superior temporal sulcus.  Important to know if another’s gaze is directed toward you or not.  Disgust  Ability to recognize facial expressions of disgust is impaired by damage to the insular cortex and basal ganglia.

15 Emotions as Response Patterns (Continued)  Neural Basis of the Communication of Emotions: Expression  Facial expressions are automatic and involuntary.  It is difficult to artificially produce realistic facial expressions of emotion.  Volitional Facial Paresis – difficulty in moving the facial muscles voluntarily; caused by damage to the face region of the primary motor cortex or its subcortical connections.

16 Emotions as Response Patterns (Continued)  Emotional Facial Paresis – lack of movement of facial muscles in response to emotions in people who have no difficulty moving the muscles; caused by damage to insular prefrontal cortex, white matter of the frontal lobe, or parts of the thalamus.

17 Feelings of Emotions  The James-Lange Theory  Theory of emotion suggesting that behaviors and physiological responses are directly elicited by situations and that feelings of emotions are produced by feedback from these behaviors and responses.  Difficult to verify experimentally.

18 Figure The James-Lange Theory of Emotion

19 Feelings of Emotions (Continued)  Feedback from Simulated Emotions  Artificial creations of facial expressions alters autonomic nervous system activity.  May reflect associations with mirror neurons.  Tendency to imitate the expressions of others appears to be innate.
