Study sheds new light on reflexive behaviors
When you touch a hot stove, your hand reflexively pulls away; if you miss a rung on a ladder, you instinctively catch yourself. Both motions take a fraction of a second and require no forethought. Now, researchers at the Salk Institute have mapped the physical organization of cells in the spinal cord that help mediate these and similar critical sensorimotor reflexes.
