Global structure of new relational knowledge networks is represented in retrosplenial complex, and node-distance in hippocampus

The paper shows that the brain encodes network structure using distinct brain regions, with hippocampus representing shortest-path distances and retrosplenial complex representing global connectivity.

Predicting real-world navigation performance from a virtual navigation task in older adults

This study finds that virtual navigation performance predicts real-world navigation in older adults for medium difficulty tasks but not easy or difficult ones.

London taxi drivers leverage regional boundaries to optimise route choices and improve their navigation skill across three decades

This study shows that London taxi drivers improve their navigation skills over decades by using regional boundaries to optimize route choices.

Video gaming, but not reliance on GPS, is associated with spatial navigation performance

This study finds that video gaming is linked to better spatial navigation performance, while GPS reliance is not, and gender differences in navigation are reduced after accounting for gaming experience.

Individuals learning to drive solo before age 18 have superior spatial navigation ability compared with those who learn later

The paper examines how starting to drive solo before age 18 affects wayfinding ability using a mobile game task and self-reported driving data.

Shorter self-reported sleep duration in men is associated with worse virtual spatial navigation performance

The paper finds that longer self-reported sleep duration in men is linked to better virtual spatial navigation performance, while no such association is found in women.

Entropy of city street networks linked to future spatial navigation ability

The paper links street network entropy in childhood environments to spatial navigation ability in adulthood using a global video game-based cognitive task.

Circuit mechanisms for chemical modulation of cortex-wide network interactions and exploration behavior

The paper identifies circuit mechanisms by which catecholamines and acetylcholine modulate cortex-wide network interactions and exploration behavior in humans.
