Membrane voltage
Ionic concentration gradients and membrane permeability determine
GHK Equation
Used to calculate the resting membrane potential
Generates signals
Voltage across the neuronal membranes
Passive voltage
Changes the membrane time constant and length constant.
The magnitude of change is proportional to current injected
Injected current changes (changes Q —> changes V) charge density on membrane by adding/taing change —> changes difference of + and -
Types of neuronal electrical signals
Passive and active
Membrane time constant
Passive voltage changes
Depolarization
Changes in membrane voltage towards a positive value
Hyperpolarization
Membrane voltage change that moves in the negative direction
