Bats Use the Same Brain Cells to Map Physical and Social Worlds

A fruit bat hanging in the corner of a cave stirs; it is ready to move. It scans the space to look for a free perch and then takes flight, adjusting its membranous wings to angle an approach to a spot next to one of its fuzzy fellows. As it does so, neurological data lifted from its brain is broadcast to sensors installed in the cave’s walls. This is no balmy cave along the Mediterranean Sea.
