...nerve cells, and implanted them into mice. The transplantation and accommodation of these cells was successful, and the scientists did not get into the common problems associated with transplanted cells, such as resulting formation of tumors. Prior to this research, creating pure neuronal cells from ES cells had been problematic as the cells...

...nerve which way to grow, says David Ginty, Ph.D., a professor of neuroscience at Hopkins and investigator of the Howard Hughes Medical Institute. But the really interesting thing is that the nerves appear to use blood vessels as guideposts to direct their growth in one of several possible directions The research team studied in mice a group...

...nerve impulses down a long stem that is surrounded by a two-layer membrane. In the neurons normal, rest state, this membrane actively sorts sodium ions to the outside of the cell and potassium ions to the inside. To transmit a nerve impulse, an electrochemical change ripples down the membrane in advance of the impulse, making it temporarily...

...nerve cells. In an inactive state, TRPV1 channels remain closed-there is no pain sensation. However, when noxious heat-temperatures above 108 degrees Fahrenheit-or capsaicin-the main ingredient in hot peppers-activates a TRPV1 channel, ions flow through, depolarizing the nerve to create an electrical current that sends pain signals to the...
