New glasses project images directly onto retina with a mini-laser

A Japanese company called QD Laser in collaboration with the University of Tokyo has developed a pair of glasses that come with a tiny camera that captures data and a laser that prints imagery from the camera directly onto ...

Action potential

An action potential (or nerve impulse) is a transient alteration of the transmembrane voltage (or membrane potential) across an excitable membrane generated by the activity of voltage-gated ion channels embedded in the membrane. Action potentials play multiple roles in several types of excitable cells such as neurons, myocytes, and electrocytes. The best known action potentials are pulse-like waves of voltage that travel along axons of neurons.
