...moving—yet it detracts from its ability to move as one cohesive piece. But less-than-best Bird is still miles better than most of today’s music: “Armchair Apocrypha” is sweeping and atmospheric, with ego-probing lyrics that spark neuron firestorms—and establish Bird as undeniably indie, at least for now. Bird is dealing with topics of self-reflection that require more existential honesty than many listeners will feel comfortable giving. Would most listeners agree with Bird when, in “Imitosis,” he sings...
...links that are emerging between movement and meaning have inspired some scientists to see the mirror-neuron system as the biological foundation on which human language is constructed. Such speculation is supported indirectly by the fact that Broca's area--a critical language center in the left hemisphere of the human brain--appears to be a close analogue of the premotor mirror region in monkeys. Broca's area, it turns out, is important for sign language as well as spoken language, and its connection to the mirror system has led Rizzolatti and U.S.C. neuroscientist Michael Arbib to propose that language...
...more severe the autism, the more depressed the activity was. The results did not surprise Dapretto. A central problem in autism, after all, is an impaired ability to understand the feelings of others, and it seems plausible, if far from proven, that a deficiency in the mirror-neuron system could be involved...
...mind's hall of mirrors will actually lead to a better understanding of autism is another question, of course, and it's only one of many that remain unanswered. But as a number of researchers see it, this is a strength rather than a weakness. For the mirror-neuron system has provided neuroscientists with a powerful new probe into the biological roots of the human psyche and prompted them to take a fresh look at old questions. Indeed, says Parma's Gallese, that's what makes the research so exciting--it's still in an early phase...
What happens biochemically, says McGaugh, is that when faced with an emotion-charged situation, such as a threat, our bodies release the stress hormones adrenaline and cortisol. Among other things, these signal the amygdala, a tiny, neuron-rich structure nestled inside the brain's medial temporal lobes, which responds by releasing another hormone, called norepinephrine. Norepinephrine does two important things. First, it kicks the body's autonomic nervous system into overdrive: the heart beats faster, respiration quickens, and the muscles tense in anticipation of a burst of physical exertion...
