How Brain Maps Memories Without Movement

Mental maps in the brain are activated when thinking about sequences of experiences, even without physical movement. In an animal study, they found that the entorhinal cortex harbors a cognitive map of experiences, which is activated during mental simulation. This is the first study to show the cellular basis of mental simulation in a nonspatial domain. The findings could enhance our understanding of brain function and memory formation.

Robot Masters Terrain with Animal-Like Gait Transitions

Researchers leveraged deep reinforcement learning (DRL) to enable a robot to adaptively switch gaits, mimicking animal movements like trotting and pronking, to traverse complex terrains effectively. Their study explores the concept of viability—or fall prevention—as a primary motivator for such gait transitions, challenging previous beliefs that energy efficiency is the key driver.

Spinal Cord Learns and Remembers Movements Autonomously

The spinal cord possesses its own learning and memory capabilities, challenging the long-held view of it as merely a message relay between the brain and body. Through innovative experiments, the team identified two distinct neuronal populations that enable the spinal cord to independently adapt and remember movements.

Deciphering Proprioception: How the Brain Maps Movement

A new study reveals the mechanisms behind proprioception, our body's innate ability to sense limb position and movement, critical for movement without visual cues. Utilizing musculoskeletal simulations and neural network models, researchers have advanced our understanding of how the brain integrates sensory data from muscle spindles to perceive bodily position and motion.

This shows a brain and computer monitor.
