Abstract

Neuroscience When a mouse sees something that quickly becomes larger in its visual field, perhaps indicating an attacking predator, it runs. Kim et al. identified a small group of neurons in the mouse retina that selectively respond to such looming visual stimuli and are required for innate defensive behaviors in response. These neurons perform this specific computation by integrating inputs from nearby neurons in a selective manner. Thus, neural circuits within the eyes, even before the information reaches the brain, perform specific computations to mediate innate, evolutionarily conserved behaviors. Sci. Adv. 10.1126/sciadv.abc9920 (2020).
