@tslominski shares highlights from the FENS conference. He covers a few interesting bits of neuroscience research he came across, relevant to spatial representation and sensorimotor processing. Some topics discussed include how a fixed number of grid-like modules emerges regardless of scale, the neural circuits required for place cell remapping, modular organization in the superior colliculus, and a theory that frames spatial salience as readiness for action. In addition, Tristan shares about the “vector hash” model, in which interactions between grid cells and place cells support error correction, pattern completion, movement-based prediction, and sequence memory.
