(Medical Xpress)—Researchers from the US and Japan have shown that an aggressive type of brain tumor can arise from normal cells in the central nervous system such as neurons. The cells revert to an earlier, undifferentiated ...
(Medical Xpress) -- Two researchers at Weill Cornell Medical College have deciphered a mouse's retina's neural code and coupled this information to a novel prosthetic device to restore sight to blind mice. The researchers ...
