Songbird vocalizations are produced by a sparse sequence of spike bursts in a motor circuit that controls the vocal output on a fast (10ms) timescale. This sparse sequence is also transmitted to song learning circuits, presumably to control the...

Visual inference of material properties like mass, compliance, elasticity or fragility is crucial to predicting and interacting with our environment. Yet, it is unclear how the brain achieves this remarkable ability. How materials move, flow, fold...

Abstract: While Attention has come to be an important mechanism in deep learning, it emerged out of a heuristic process of trial and error, providing limited intuition for why it works so well. Here, we show that Transformer Attention closely...
