Clover-like object vector representations support human spatial cognition

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 […]

Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf

Kavli Affiliate: Avi Shporer | First 5 Authors: Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía, David Charbonneau, Allyson Bieryla | Summary: TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textit{Tierras} Observatory to monitor both the long-term photometric variability of TOI-3884 and changes […]
