Even when other powers have been lost and people may not even be able to understand language, they will nearly always recognize and respond to familiar tunes. And not only that. The tunes may carry them back and may give them memory of scenes and emotions otherwise unavailable for them.
Oliver SacksIf we wish to know about a man, we ask 'what is his story--his real, inmost story?'--for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us--through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse, our spoken narrations. Biologically, physiologically, we are not so different from each other; historically, as narratives--we are each of us unique.
Oliver SacksThus the feeling I sometimes have - which all of us who work closely with aphasiacs have - that one cannot lie to an aphasiac. He cannot grasp your words, and cannot be deceived by them; but what he grasps he grasps with infallible precision, namely the expression that goes with the words, the total, spontaneous, involuntary expressiveness which can never be simulated or faked, as words alone can, too easily.
Oliver SacksThere are, of course, inherent tendencies to repetition in music itself. Our poetry, our ballads, our songs are full of repetition; nursery rhymes and the little chants and songs we use to teach young children have choruses and refrains. We are attracted to repetition, even as adults; we want the stimulus and the reward again and again, and in music we get it. Perhaps, therefore, we should not be surprised, should not complain if the balance sometimes shifts too far and our musical sensitivity becomes a vulnerability.
Oliver SacksWith any hallucinations, if you can do functional brain imagery while theyre going on, you will find that the parts of the brain usually involved in seeing or hearing - in perception - have become super active by themselves. And this is an autonomous activity; this does not happen with imagination.
