Brain-machine interface study reveals how intentions and actions are linked in time

Researchers led by Jean-Paul Noel at the University of Minnesota, United States, have decoupled intentions, actions and their effects by manipulating the brain-machine interface that allows a person with otherwise paralyzed arms and legs to squeeze a ball when they want to.

How Intent Shapes Perception of Action

A groundbreaking study used a brain-machine interface to explore how intentions, actions, and their outcomes are temporally linked in the human brain. By recording single-neuron activity from a paralyzed individual with implanted electrodes, researchers enabled intentional hand movement through machine-learning-driven muscle stimulation.
