Brain-computer interfaces could allow soldiers to control weapons with their thoughts and turn off their fear – but the ethics of neurotechnology lags behind the science

From warfare to entertainment and VR, brain-computer interface development has extended beyond prosthetics for patients with disabilities. Missing is full ethical consideration of the consequences.

Illuminating the brain one neuron and synapse at a time – 5 essential reads about how researchers are using new tools to map its structure and function

From figuring out where memories are stored to how sensory information translates to behavior, new technologies are helping neuroscientists better understand how the brain works.

Restoring touch through electrodes implanted in the human brain will require engineering around a sensory lag

When designing neuroprosthetic devices for users to control with their thoughts, engineers must take into account the sensory information brains collect from the environment and how it gets processed.

Melding mind and machine: How close are we?

Brain-computer interfacing is a hot topic in the tech world, with Elon Musk’s announcement of his new Neuralink startup. Here, researchers separate what’s science from what’s currently still fiction.
