Detailed explanation-1: -The Dictionary of Neurological Signs defines abulia as a “syndrome of hypofunction, ‘’ characterized by lack of initiative, spontaneity, and drive, apathy, slowness of thought (bradyphrenia), and blunting of emotional responses and response to external stimuli.
Detailed explanation-2: -Caudate neurons encode both visual and reward information We predicted that, if the caudate nucleus contributes to integrating these different sources of information, then the activity of individual neurons would be modulated by properties of both the visual motion evidence and the reward context.
Detailed explanation-3: -Restlessness, disinhibition, and confusion occurred in 4 patients with lesions circumscribed to the caudate nucleus. Agitation, anxiety, and talkativeness were common signs in other series of patients with caudate lesions.
