Rewrite the textbooks: Findings challenge conventional wisdom of how neurons operate
(PhysOrg.com) -- Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body (input), and axons carry signals away (output). In one ...

How injured nerves grow themselves back
Unlike nerves of the spinal cord, the peripheral nerves that connect our limbs and organs to the central nervous system have an astonishing ability to regenerate themselves after injury. Now, a new report in the October 1st ...
