Neurologist Oliver Sacks, author of "Musicophilia: Tales of music and the Brain", studied neurological oddities in people, trying to understand how the brain works. He concluded that people with some type of frontal lobe damage often “produced not only severe difficulties with expressive language (aphasia) but a strange access of musicality with incessant whistling, singing and a passionate interest in music. For him, this was an example of normally suppressed brain functions being released by damage to others”. Sacks had a genuine interest in trying to help people affected with neurological disorders and other phenomena associated with music, and how it can provide access to otherwise unreachable emotional states, revivify neurological avenues that have been frozen, evoke memories of earlier, lost events or states of being and attempts to bring those with neurological disorders back to a time when the world was much richer for them. He was a firm believer that music has the power to heal.
