In a first, human brain organoids placed in the mouse cortex react to visual stimuli
In order to study organoids, researchers are combining cutting-edge neural recording techniques, and they believe that this will provide a one-of-a-kind platform for evaluating organoids as models for both brain development and disease as well as looking into their potential application as neural prosthetics to replace lost, degenerated, or damaged brain regions.
