Our experience of the world seems to divide naturally into discrete, temporally extended events, yet the mechanisms underlying the learning and identification of events are poorly understood. Research on event perception has focused on transient elevations in predictive uncertainty or surprise as the primary signal driving event segmentation.

Researchers discover workings of brain’s ‘GPS system’

The study, pub­lished in the jour­nal Nature, indi­cates that cer­tain position-tracking neu­rons — called grid cells — ramp their activ­ity up and down by work­ing together in a col­lec­tive way to deter­mine loca­tion, rather than each cell act­ing on its own as was pro­posed by a com­pet­ing theory. Full Story.
