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.Moreover, the distinctions based on function between neurons and other cells such as cardiac and muscle cells are not helpful.Thus, the fundamental difference between a neuron and a nonneuronal cell is a matter of degree.The Hodgkin–Huxley model of an action potential in the squid giant axon has been the basis for much of the current understanding of the ionic bases of action potentials.Briefly, the model states that the generation of an action potential is determined by two ions: Na and K .Plastic change often results from the alteration of the number of neurotransmitter receptors located on a synapse.
If more of the same type of postsynaptic receptors are activated, then more Na will enter the postsynaptic membrane and depolarize cell.
Neurons are diverse with respect to morphology and function.
Thus, not all neurons correspond to the stereotypical motor neuron with dendrites and myelinated axons that conduct action potentials.
Cellular neuroscience is the study of neurons at a cellular level.
This includes morphology and physiological properties of single neurons.
