RIKEN Neuron paper: thalamic reticular nucleus controls representation updating for history-based decisions
melnykowycz · x · 2026-10-22
A new Neuron paper from RIKEN CBS and the University of Tokyo proposes a mechanism for how sensory memories are held and reset in the brain, starring the thalamic reticular nucleus (TRN) alongside higher-order thalamus (pulvinar) and PPC. Pulvinar acts as a 'steadying hand' while TRN works like an 'alarm button', jointly controlling representation updates to enable history-based decision-making. The poster also shared a toy model and notes.
