6152515 Music, uniquely among the arts, is both completely abstract and profoundly emotional. It has no power to represent anything particular or external, but it has a unique power to express inner states or feelings. Music can pierce the heart directly; it needs no mediation. arts feelings music neuroscience Oliver Sacks

4a76167 There 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. science music songs hypothesis neuroscience theories hypotheses psychology Oliver Sacks
ca6c23d If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery. neuroscience well-being Sam Harris
eeead5d "There is certainly a universal and unconscious propensity to impose a rhythm even when one hears a series of identical sounds at constant intervals... We tend to hear the sound of a digital clock, for example, as "tick-tock, tick-tock" - even though it is actually "tick tick, tick tick." music neuroscience Oliver W. Sacks
b35a999 Recent brain scans have shed light on how the brain simulates the future. These simulation are done mainly in the dorsolateral prefrontal cortex, the CEO of the brain, using memories of the past. On one hand, simulations of the future may produce outcomes that are desirable and pleasurable, in which case the pleasure centers of the brain light up (in the nucleus accumbens and the hypothalamus). On the other hand, these outcomes may also have a downside to them, so the orbitofrontal cortex kicks in to warn us of possible dancers. There is a struggle, then, between different parts of the brain concerning the future, which may have desirable and undesirable outcomes. Ultimately it is the dorsolateral prefrontal cortex that mediates between these and makes the final decisions. (Some neurologists have pointed out that this struggle resembles, in a crude way, the dynamics between Freud's .) mind neuroscience brain simulation freud prediction Michio Kaku
68fb37e our moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy. morality neuroscience Sam Harris
743ae19 Given her deafness, the auditory part of the brain, deprived of its usual input, had started to generate a spontaneous activity of its own, and this took the form of musical hallucinations, mostly musical memories from her earlier life. The brain needed to stay incessantly active, and if it was not getting its usual stimulation..., it would create its own stimulation in the form of hallucinations. science music musical-hallucinations hallucinations neuroscience psychology Oliver Sacks
5ba39ab "... [O]ne of the most influential approaches to thinking about memory in recent years, known as connectionism, has abandoned the idea that a memory is an activated picture of a past event. Connectionist or neural network models are based on the principle that the brain stores engrams by increasing the strength of connections between different neurons that participate in encoding an experience. When we encode an experience, connections between active neurons become stronger, and this specific pattern of brain activity constitutes the engram. Later, as we try to remember the experience, a retrieval cue will induce another pattern of activity in the brain. If this pattern is similar enough to a previously encoded pattern, remembering will occur. The "memory" in a neural network model is not simply an activated engram, however. It is a unique pattern that emerges from the pooled contributions of the cue and the engram. A neural network combines information in the present environment with patterns that have been stored in the past, and the resulting mixture of the two is what the network remembers... When we remember, we complete a pattern with the best match available in memory; we do not shine a spotlight on a stored picture." engrams neuroscience recollection memory psychology Daniel L. Schacter
7665d92 "The seat of consciousness and intelligence was from the earliest times regarded by the Egyptians as both the heart and the bowels or abdomen. Our surgeon, however, has observed the fact that injuries to the brain affect other parts of the body, especially in his experience the lower limbs. He notes the drag or shuffle of one foot, presumably the partial paralysis resulting from a cranial wound, and the ancient commentator carefully explains the meaning of the obsolete word used for "shuffle." ancient-medicine neuroscience brain James Henry Breasted
c829b63 The attention given to the side of the head which has received the injury, in connection with a specific reference to the side of the body nervously affected, is in itself evidence that in this case the ancient surgeon was already beginning observations on the localization of functions in the brain. ancient-medicine hieroglyphic injuries medical-history neuroscience biology brain ancient-egypt James Henry Breasted
