Musicophilia Tales of Music and the Brain by Oliver Sacks

Music can move us to heights or depths of emotion. It can persuade us to buy something or remind us of our first date.It can lift us out of depression when nothing else can. It can get us dancing. But the power of music goes much, much further .Indeed, music occupies more areas of our brain than language does - humans are musical species.
Oliver Sacks compassionate, compelling tales of people struggling to adapt to differant neurological conditions have fundamentally changed the way we think of our brains, and of human experience of patients, musicians, and everyday people- from a man who is struck by lightning and suddenly inspired to become a pianist at the age of forty- two, to an entire group of children with Wiliams synrome who are hypemuscical from birth.
Our exquisite sensititvity to music can sometimes go wrong.Sacks explores how catchy tunes can subject us to hours of mental replay, and how a suprising number of people acquire non-stop  musical hallucinaions.
Yet far more frequently, music goes right : it can animate people with Parkinsons disease who cannot otherwise move give words to stroke patients who cannot otherwise speak, and calm and organize people whose memories are ravaged by Alzheimers or amnesia.
