'Flakka': How dangerous is the new street drug? A designer street drug called 'Flakka' is making headlines again with a new incident involving four people going on a rampage in Sullivan, Missouri. What is Flakka and just how dangerous is it?
Voltage clamp. The voltage clamp is an experimental method used by electrophysiologists to measure the ion currents through the membranes of excitable cells, such as neurons, while holding the membrane voltage at a set level.
Voltage (volts) is the pressure between a negative and positive charge. Current (amperes) is the amount of electrons moving from one point to the next I like to compare the whole thing to water flowing thru a garden hose. What direction the water flows, at what pressure and how much.
