Earlier this year, researchers from Russia's Neurobotics Corporation and a team at the Moscow Institute of Physics and Technology worked out how to visualize human brain activity by mimicking images observed in real-time. This breakthrough in artificial neural network technology usage will eventually enable post-stroke rehabilitation devices that will be controlled by signals from the brain. The team uploaded their research via a'preprint' on the bioRxiv website and also shared a video that showcased their'mind-reading' device at work. To develop devices that can be controlled by the human and treatments for cognitive disorders or post-stroke rehabilitation, neurobiologists must have an understanding of how the brain encodes data and information. A critical development in the creation of these technologies is the ability to study brain activity using visual perception as a marker.
