After neurotransmitters are synthesized, they are packaged and stored in vesicles.

Although slower than ionotropic receptors that function as on-and-off switches, metabotropic receptors have the advantage of changing the cell's responsiveness to ions and other metabolites, examples being gamma amino-butyric acid (inhibitory transmitter), glutamic acid (excitatory transmitter), dopamine, norepinephrine, epinephrine, melanin, serotonin, melatonin, and substance P.As Na ions enter the cell, the membrane potential is further depolarized, and more voltage-gated sodium channels are activated.Such a process is also known as a positive feedback loop.Several techniques such as intracellular recording, patch-clamp, and voltage-clamp technique, pharmacology, confocal imaging, molecular biology, two photon laser scanning microscopy and Ca2 imaging have been used to study activity at the cellular level.

Cellular neuroscience examines the various types of neurons, the functions of different neurons, the influence of neurons upon each other, how neurons work together.Neurons are cells that are specialized to receive, propagate, and transmit electrochemical impulses.
