Document Summary
Sparks favored the idea that electrical signals crossed synapses. Soups thought neurons released a chemical that flowed across synapses. Exogenous substances: substances from outside the body. Endogenous substance: a substance inside the body. Most drugs affect behavior by affecting the chemical communication process at millions, or even billions, of synapses. Electrical signals are turned into chemical signals at. Calcium induced synaptic vesicles fuse with the presynaptic membrane, spilling molecules of neurotransmitter into the synaptic cleft: neurotransmitter: also called simply transmitter. A signaling chemical, released by a presynaptic neuron, that diffuses across the synaptic cleft to alter the functioning of the postsynaptic neuron: exocytosis: a cellular process that results in the release of a substance into the extracellular space. The neurotransmitter molecules then bind to neurotransmitter receptors that span the membrane of the postsynaptic cell, which receives the chemical signal: neurotransmitter receptor: also called simply receptor.
