Membrane potential function as a battery, providing power to operate a variety of "molecular devices" embedded in the membrane. Second, in electrically excitable cells such as neurons and muscle cells, it is used for transmitting signals between different parts of a cell. Signals are generated by opening or closing of ion channels at one point in the membrane, producing a local change in the membrane potential. This change in the electric field can be quickly affected by either adjacent or more distant ion channels in the membrane. Those ion channels can then open or close as a result of the potential change,
Pinky and the Brain the head. A few times in the series Pinky and Brain indeed pondered the same thing, though in one of these Pinky dismissed his idea as being too stupid. Just one time the answer was "Yes I am!", when Pinky's intelligence is elevated to match Brain's. In another episode, it turns out that what Pinky was pondering was that he and Brain never ponder the same thing, which turned out to be part of what Brain was pondering as well. In a short episode ("Pinky's POV") the spectator sees everything Pinky sees (including his imaginations) and hears his thoughts. His
