Your Brain Thinks It Knows Where It Is…. Even When It Doesn’t

Universe Today - Wed, 04/29/2026 - 12:26pm

Astronauts take time to adjust how firmly they grip and handle objects when moving between Earth and space, because the brain continues making predictions based on whichever gravitational environment it has most recently adapted to. Research from the Université catholique de Louvain reveals that this adjustment process works in both directions and sheds new light on how the brain anticipates and manages the risk of making mistakes.
