Neuron contacts another neuron's dendrite, soma or, less commonly, axon. Neurons such as Purkinje cells in the cerebellum can have over 1000 dendritic branches, making connections with tens of thousands of other cells; other neurons, such as the magnocellular neurons of the supraoptic nucleus, have only one or two dendrites, each of which receives thousands of synapses. Synapses can be excitatory or inhibitory and either increase or decrease activity in the target neuron, respectively. Some neurons also communicate via electrical synapses, which are direct, electrically conductive junctions between cells. In a chemical synapse, the process of synaptic transmission is as follows:
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
