Detailed explanation-1: -Evidence from different functional neuroimaging studies suggest that there is a reduced activity of right ventromedial and ventrolateral prefrontal cortices and an increased activity of left amygdala, left anterior cingulate cortex, and left basal ganglia in mania.
Detailed explanation-2: -Limbic cortex. This part contains two structures, the cingulate gyrus and the parahippocampal gyrus. Together, they impact mood, motivation, and judgement.
Detailed explanation-3: -Both a manic and a hypomanic episode include three or more of these symptoms: Abnormally upbeat, jumpy or wired. Increased activity, energy or agitation. Exaggerated sense of well-being and self-confidence (euphoria)
Detailed explanation-4: -One of the regions of the prefrontal cortex that is most affected both by depression and by the manic phase of manic depression is the ventromedial cortex (also known as the subgenual cortex, because it sits beneath the genua, or knee, of the corpus callosum).
