NEUROANATOMY OF EMOTIONS Joanna Haahti Group 4 CONTENT 1. BASIC EMOTIONS 2. THEORIES OF EMOTION 3. NEUROANATOMY OF EMOTIONS LOCATIONIST APPROACH PSYCHOLOGICAL CONSTRUCTIONIST APPROACH 4. CONCLUSION BASIC EMOTIONS • The six basic emotions: • Relatively consistent across cultures • Suggested to be based on human biology COUNTLES AMOUNT OF EMOTIONS • The six basic emotions can be devided in to countless different emotions • Research of emotions is mainly concentrated on the six basic emotions THEORIES OF EMOTION • The James-Lange theory of emotion • The Cannon-Bard theory of emotion • The Two-Factor theory of emotion THE JAMES-LANGE THEORY OF EMOTION THE CANNON-BARD THEORY OF EMOTION THE TWO-FACTOR THEORY OF EMOTION NEUROANATOMY OF EMOTIONS • Areas of shared and spesific activations • Hemispheric differences • Right hemisphere: negative • Left hemisphere: positive • Two approaches to neuroanatomy of emotions • Locationist approach • Psychological constructionist approach LOCATIONIST APPROACH Emotion categories are assumed to be spesifically localized to discrete brain locales or anatomical networks PSYCHOLOGICAL CONSTRUCTIONIST APPROACH Emotions are psychological events that emerge from more basic operations that are not spesific emotions • Core affect = Pink • Conceptualization = Purple • Language = Green • Executive attention = Orange COMPARISON OF APPROACHES LOCATIONIST APPROACH Amyglada: Fear The anterior insula: Disgust The orbitofrontal cortex: Anger The anterior cingulate cortex: Sadness PSYCHOLOGICAL CONSTRUCTIONIST APPROACH Amyglada: Emotional learning and memory Responses to relevant Stimuli Regulation of Emotion The anterior insula: Core affective feelings in awareness Awareness and bodily sensations The orbitofrontal cortex: Integrates sensory information to guide behaviour Decision making and learning The anterior cingulate cortex: Takes part in operations related to realizing the core affect CONCLUSION • There are six relatively consistent basic emotions across cultures: anger, disgust, fear, happiness, sadness and surprise • Locationist approach: emotion categories are assumed to be spesifically localized to discrete brain locales or anatomical networks • Psychological constructionist approach: emotions are psychological events that emerge from more basic operations that are not spesific emotions
