In How Brain Arousal Mechanisms Work, neuroscientist Donald Pfaff presents his theoretical ideas on the organization of brain arousal systems that he names, ˇ°Generalized Arousal (GA)ˇ±. The main purpose of the book is to offer explanation of the mechanisms of brain arousal toward physical consciousness so that it can be applied for treatment purposes. %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6430173/
