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 Labs research facility. Brain is self-centered and scheming, Pinky is good-natured but feebleminded. In each episode, Brain devises a new plan to take over the world which ultimately ends in failure: usually due to Pinky's idiocy, the impossibility of Brain's plan, Brain's own arrogance, or just circumstances beyond their control. In common with many other "Animaniacs" shorts, many episodes are in some way a parody of something else, usually a film or novel. Many of the "Pinky and the Brain" episodes occur in the 1990s at Acme Labs, located in some large American city underneath a suspension bridge. Several episodes
