Document Summary
Cerebral hemispheres: the two halves of the brain"s cerebrum, left and right. Corpus callosum: the band of nerve fibers that connects the two hemispheres of the brain. Hemispheric lateralization: the process by which ach half of the brain becomes specialized for certain functions. Avoidant emotions such as distress, fear and disgust. Scientists and clinicians have long presumed the two cerebral hemispheres had different functions in the affective domain (john hughes. Evidence from a variety of sources (brain injury, sodium amytal studies, brain imaging) suggested hemispheres differentially involved in emotion. Left frontal cortex involved in approach-related emotions (e. g. joy, happy, interest) Right frontal cortex involved in withdrawal related emotions (e. g. fear, anger disgust) Pattern of resting frontal eeg activity may reflect basic approach-avoidance tendencies. Pattern of asymmetry may reflect individual differences in affective style. Over 100 empirical studies in support of this idea. *****anger mentioned as controlled by both the right and left hemisphere . look into this.
