The amygdala is associated with emotions, impulses, aggression and instinctive behaviour. Emotional learning most commonly has been studied in both animal models and humans, using Pavlovian conditioning, in which an otherwise neutrally conditioned stimulus is paired with an innately aversive unconditioned stimulus. Amygdala stimulation reliably improved later object-recognition memory with no elicited emotional response, and this memory enhancement was reflected by specific neuronal oscillations between the amygdala and memory-related regions. 2005-2023 Psych Central a Red Ventures Company.

The fight-flight-freeze response can show up in many life situations, including: Sometimes, the fight-flight-freeze response is overactive. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream. This hormone also causes the blood vessels to contract, allowing the body to redirect blood to the major muscle groups, including the heart and lungs. Recognize any bodily changes youre experiencing.

If a threat is not serious, the frontal lobes tend to take control, and most people will respond with a more logical, thought-out reaction. To test that idea, Willie, Inman, Manns, and colleagues recruited 14 epilepsy patients who were to undergo surgery that required inserting intracranial depth electrodes to monitor seizure activity during the procedure. In addition, human neuroimaging studies suggest a role for the amygdala in mediating the so-called framing effect during economic choices, which is thought to reflect the effect of positive or negative emotion on decision making.
