Chemical synapse cells, known as a gap junction. At gap junctions, cells approach within about 3.5 nm of each other, rather than the 20 to 40 nm distance that separates cells at chemical synapses. As opposed to chemical synapses, the postsynaptic potential in electrical synapses is not caused by the opening of ion channels by chemical transmitters, but rather by direct electrical coupling between both neurons. Electrical synapses are faster than chemical synapses. Electrical synapses are found throughout the nervous system, including in the retina, the reticular nucleus of the thalamus, the neocortex, and in the hippocampus. While chemical synapses are found
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
