It is an outward expression of the internal state of an individual.
Mental component – Cognition
- Conative changes
Genesis of emotion: Hypothalamus and limbic system
Emotions If only it were as simple as the diagrams below…
Hippocampus – determines the emotional relevance of incoming stimuli from the frontal cortex and the cingulate cortex
- involved in Declarative Memory (cold hard facts) taken in from cortical areas
sensory 2/3 areas hippocampus (LTP)
Amygdala – responsible for elaborating on the emotional response and directing the hypothalamus to respond.
Cognitive Circuit Precognitive Circuit Feedback
Areas of the hypothalamus and limbic system
Aggression: Amygdala and hypothalamus.
Fear : Amygdala and hypothalamus
Rage: Wide area from lateral hypothalamus to central grey matter of mid-brain. It is also seen in decorticate animal.
Placidity: destructing amygdaloid bilaterally
Hypothalamus (feeding and satiety centers).
Sexual drive and behavior: Neocortex plays a dominant role
Hypothalamus and limbic system ( cingulate gyrus and retrosplenial portion of limbic system- maternal feeling is lost)
Fear Response Before Training – a transient orienting response is induced to the sound Training – sound is paired with the shock After Training – placement in the box induces freezing when the sound is present.
Hypothalamus: Integrates the endocrine, autonomic and motor activities to form an appropriate emotional behavior.
Cerebral cortex : Detailed processing the conscious experience of emotional feeling and provides the neural mechanisms
Limbic system: elaboration and integration of the activity and also involved in ascending pathways to some areas in cortex.
