Brain Facts is a primer on the brain and nervous system, published by the Society for Neuroscience. Brain Facts is a valuable resource for educators, students, and anyone interesting in learning about neuroscience. Two amygdalae reside in the brain, one in each hemisphere. It was found that the functional connectivity between the amygdala and the prefrontal cortex was altered in those with internet addiction, concluding that this type of addiction may be associated with emotional disturbances and with the processing of emotions (Cheng & Liu, 2020). Also, deep brain stimulation has shown promising results in helping to relieve some of the psychological and behavioral side effects such as hypervigilance. After repeated pairing of these two stimuli, the neurons within the amygdala will be conditioned to the change in stimuli, reflecting a conditioned fear response. Overly aggressive if there is hyperactivity of the amygdala. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms.
