Ion Concentration Gradients in AP Psychology

Definition

Ion concentration gradients refer to differences in ion concentrations between the inside and outside of a neuron's cell membrane. These gradients create an electrochemical gradient that influences neuronal activity.

Membrane Potential: Membrane potential refers to the difference in electric charge between the inside and outside of a cell membrane, which allows for various cellular processes including nerve impulses.

Diffusion: Diffusion is the process where particles move from areas with higher concentration to lower concentration until equilibrium is achieved.

Electrochemical Gradient: Electrochemical gradient refers to the combined influence of ion concentration gradients and electrical forces on ion movement across a cell membrane.
