Scientists studied the brain activity of school-aged children during development and found that regions that activated upon seeing limbs (hands, legs, etc.) subsequently activated upon seeing faces or words when the children grew older. The research, by scientists at Stanford University, Palo Alto, California, reveals new insights about vision development in the brain and could help inform prevention and treatment strategies for learning disorders. The study was funded by the National Eye Institute and is published in Nature Human Behaviour.
It is possible to re-create a bird’s song by reading only its brain activity, shows a first proof-of-concept study from UC San Diego. Reproducing the songbird’s complex vocalizations – down to the pitch, volume and timbre of the original – lays the foundation for building vocal prostheses for humans who have lost their ability to speak.
