Imagine trajectory and navigate to target
Part of Nicoleis's Walk Again Project
Read brain waves and translate to signals to control assistive devices
Used by severely disabled patients
Experiment
Hair-thin microfilaments in macaques brains
Trained to navigate their wheelchairs to reward
Translate their brain activity into digital motor commands
Monkeys got better over time - efficient
Implants
Surgery and permanent
Durability - microfibres adhere
Don't damage
Next - Human trials
