in an eel's spinal cord to help develop a microchip implant that may someday help paralyzed people walk again. After a spinal cord injury, many patients are unable to move because the brain is cut off from nerve control centers called central pattern...

Research on nerve cell circuitry reveals clue about schizophrenia
