These “behavioral syllables ” can be reused by the brain to achieve specific goals. view more It might not rival Newton’s apple, which led to his formulating the law of gravity, but the collapse of a lighting scaffold played a key role in the discovery that mice, like humans, have body language. Harvard Medical School scientists have developed new computational techniques that can make sense of the bodily movements of mice, organizing them into notions of syllables and grammar. Along the way they also proposed a solution to a longstanding problem in neuroscience–how to objectively study complex three-dimensional patterns of animal behavior without relying on subjective human observers. Their results appear in Neuron. “If you look into…
