Brain-machine interface technologies have opened up the possibility that the visually impaired will be able to see by virtue of digital-camera technologies interfacing directly with the visual regions of the cerebral cortex through electrode implants. People paralyzed due to central nervous system damage can look forward to the day when artificial limbs interfacing with motor …

Stem-cell research aimed at regenerating nerve cells in the human brain is moving forward. Researchers have already isolated a particular gene that directs certain stem cells to turn into cerebral cortex cells. These are the cells comprising the outer layer of the cerebrum, the upper part of the brain largely responsible for cognition. Researchers have …
