摘要:A key function of brain systems mediating emotion is to learn to anticipate unpleasant experiences. Although organisms readily associate sensory stimuli with aversive outcomes, higher-order forms of emotional learning and memory require inference to extrapolate the circumstances surrounding directly experienced aversive events to other indirectly related sensory patterns that were not part of the original experience. This type of learning requires internal models of emotion, which flexibly tra...

摘要:Vision enables many animals to perform spatial reasoning from remote locations1. By viewing distant landmarks, animals recall spatial memories and plan future trajectories. Although these spatial functions depend on hippocampal place cells2,3, the relationship between place cells and active visual behaviour is unknown. Here we studied a highly visual animal, the chickadee, in a behaviour that required alternating between remote visual search and spatial navigation. We leveraged the head-direct...
