A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song.

To test the system, the team used mice engineered to have light-responsive cortical neurons. They trained the mice to associate a particular pattern of brain stimulation with a reward. In a series of ...

Restoring lost senses or delivering precise brain signals has required invasive hardware and can’t mimic the brain’s natural, distributed activity patterns. This platform shows the brain can learn to ...

The brain is the most energy-demanding organ in the body, in part due to its complexity. Its components are varied and intricate: comprising different cell types, including neurons designed to ...
