The front of the brain's job is impulse control and selective attention. Because of my anxiety, my brains frontal lobes were working too hard. Doing normal things burned me out. Everything took effort not to have a nervous breakdown. Impulse control allows the brain to self-organize. It allows you to see and hear more. and have more fluid motor control. With attention, detached observation allows enhanced perception. The process is controlled distraction does not interfere with growing new connections for perception. Motor control learns balance faster again correcting for interference. When under stress interference cannot be canceled out as noise and so perception and balance cannot develop with connection growth. The faster the frontal lobes cancels noise the faster one learns and becomes smarter.
