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...

摘要：In the past decade, hundreds of exoplanets have been discovered in extremely short orbits below 10 days. Unlike in the Solar System, planets in these systems orbit their host stars close enough to disturb the stellar magnetic field lines1. The interaction can enhance the magnetic activity of the star, such as its chromospheric2 and radio3 emission or flaring4. So far, the search for magnetic star-planet interactions has remained inconclusive. Here we report the detection of planet-induced flar...
