POLARIZED MEMBRANE

The Polarized Membrane in Neurophysiology Core Definition and Mechanisms The concept of the Polarized Membrane is foundational to biological psychology and neuroscience, describing the inherent electrical charge differential maintained across the boundary of all living cells, most critically, excitable cells like neurons and muscle fibers. Fundamentally, a membrane is considered polarized when there is an […]

RESTING POTENTIAL

The Resting Potential of Excitable Cells The Core Definition of Resting Potential The resting potential is defined as the imbalance of electrical charge which is present between the interior of an electrically excitable cell, such as a nerve cell or muscle fiber, and its surrounding extracellular fluid. This potential difference is maintained when the cell […]
