Neurotransmitter's Action

The process by which neurotransmitters are released by a neuron, bind to and activate the receptors of another neuron.

Resting Potential

The difference in electric charge between the inside and outside of a resting neuron, providing the cell with the potential to generate an action potential.

Neural Membrane

The lipid bilayer that encloses the cytoplasm of a neuron, maintaining the electrical potential used in signal transmission.

Electrical Polarization

The phenomenon where in a material, or in the particles of the material, there is a separation of charge leading to one part becoming more positively charged and another part more negatively charged.
