Week 6: Emotion Flashcards
Monogamy
Associated with differences in oxytocin binding
Methods in affective neuroscience
Neuroimaging, brain stimulation, electrophysiology, lesion studies, behavioural experiments
Neuroimaging
PET, fMRI
PET
Analyzing decay of radioactive tracer isotope
fMRI
Analyzing hemodynamic responses
Brain stimulation
Transcranial magnetic stimulation, transcranial direct current stimulation
Electrophysiology
EEG, MEG, single unit recordings of a neuron, microstimulation
Darwin and emotion
Compares sketches/photos of emotions in animals and humans, they are homogenous, a set of basic emotions are present throughout species
Ekman
6 basic emotions that are universally recognizable: happiness, sadness, anger, fear, disgust, surprise
Basic emotion theory
Proposed a limited set of basic emotions that are universal, biologically inherited and have unique physiological and neural profiles that distinguish them from one another (not true!)
Why is basic emotion theory not correct?
Fundamental processes of emotion are shared across brain regions, brain does not have one distinct system for each emotion
Dual systems account
Withdrawal system, approach system
Withdrawal system
Causes you to avoid aversive stimuli, fear, disgust, amygdala, anterior insula
Approach system
Causes you to approach desirable goals, happiness, enthusiasm, pride, reward system
Example that amygdala is a central structure in the withdrawal system
Kluver-bucy syndrome, patient SM
