Clover-like object vector representations support human spatial cognition

Posted by dbos June 14, 2025June 18, 2025NTNU, This Week: Neuroscience

Kavli Affiliate: Jonathan Whitlock | Authors: Marcia Becu, Ivan Markel Krasovec, Pearl Saldanha, Jonathan Whitlock and Christian F Doeller | Summary: Vector-based spatial coding has been demonstrated in rodents, yet its neural basis in humans and its contribution to navigation remain poorly understood. Using a novel spatial updating task, we show that egocentric directional signals […]
