For example, rats who had their amygdala removed cuddled up with and showed no fear in the presence of cats one of their natural predators. Apart from this, a damage to the Hippocampus can also cause poor impulse control, hyperactivity, and difficulty with spatial navigation or memory. Exploring the intersections of neuroscience and society. That deficit appears to be due to difficulties in directing attention to the eyes of others, which is important for discerning fear. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. The amygdala plays a prominent role in mediating many aspects of emotional learning and behaviour. When a person feels stressed or afraid, the amygdala releases stress hormones that prepare the body to fight the threat or flee from the danger.

A large body of literature supports a role for the amygdala in those functions, presumably by virtue of amygdalar projections to the prefrontal and sensory cortices, to the hippocampus and rhinal cortices, and to subcortical neuromodulatory systems. Subject : "I just feel like everything is all wrong. 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. In mania, there seems to be increased activity of certain parts of the brain.
