Neural Basis Of Emotion

NEURAL BASIS OF EMOTION

Neural basis of emotions

The amygdala organizes behavioral, autonomic, and hormonal responses to a variety of situations, including those that produce fear, anger, or disgust. In addition, it is involved in the effects of odours and pheromones on sexual and maternal behaviour. It receives inputs from the olfactory system, the association cortex of the temporal lobe, the frontal cortex, and the rest of the limbic system. The outputs go to the frontal cortex, hypothalamus, hippocampal formation, and brain stem nuclei that control autonomic functions and some species-typical behaviours.

Neural basis of emotions

Group of neurons in the amygdala responds primarily to faces . They are probably part of a system which has evolved for the rapid and reliable identification of individuals from their faces, and of facial expressions, because of the importance of this in primate social behavior. Consistent with this, activation of the human amygdala can be produced in neuroimaging studies by some face expressions, and lesions of the human amygdala may cause difficulty in

Neural basis of emotions

• In the central nervous system acetyl choline is involved in wakefulness, attentiveness, anger, aggression, sexuality, and thirst . Dopamine, Serotonin, Oxytocin, and Endorphins are the quartet responsible for your happiness • Depression, anxiety and other mood disorders are thought to be directly related to imbalances with neurotransmitters. The four major neurotransmitters that regulate mood are Serotonin, Dopamine, GABA and Norepinephrine.

Neural basis of emotions

When operating properly, the nervous system maintains an equilibrium between inhibitory neurotransmitters (calming) – GABA & Serotonin and excitatory (stimulating) – neurotransmitters Dopamine, Norepinephrine, Epinephrine and Glutamate
