Neurophysiology is the study of the function of the nervous system.
Membrane Ion Channels
All animal cells are enclosed in a plasma membrane, which separates its cytoplasm with the extracellular environment. Cell membrane has the structure of a lipid bilayer, with large molecules embedded in it. Concentration of ions are different across the cell membrane, with more sodium ions (Na+) and chloride ions (Cl-) outside the cell, and more potassium ions (K+) and negative charged protein molecules (A-) inside the cell.
