electrical properties of Neurons
Neurons send electrical signals down their axons to communicate with
other neurons through neurotransmitter release.
They are able to do this by maintaining a negative resting potential
relative to the extracellular space.
Synapse propagation
Action potentials propagate
via voltage-gated Na+ and K+
channels that cause depo-
larization and repolarization,
respectively.
Concentration gradient is
restored by a Na+/K+ pump
which pushes 3 Na+ out and 2
K+ ions in.
Ionic concentrations in neurons
K+ is in equilibrium due to opposing forces that balance
out at resting membrane potential
Na+
Na+K+ K+
K+
Neurons are highly interconnected
Along each axon and at each synapse is a delicate balance of
electrical charge and current
Disrupting this balance will result
in altered communication between
neurons
