Biological Sciences / The Royal Society, volume 275, pages 2353-2361.   The use of five hyphens in a title is unusual, and predicts accurately some unusual ideas, most notably that to flee is a decision and to freeze is a choice, that findings from the visual sense generalise to the other senses, and that the faster of the two mammalian systems that process stimuli is "thalamic" while the slower system is "cortical". Whatever happened to reflexes, instincts and the brainstem? The lack of integration implicit in hyphenation is further expressed in the steady introduction of new references as the paper progresses, and through a penultimate paragraph about "hybrid images".
