Nerve Impulse Transmission within a Neuron: Resting Potential
The resting potential of a neuron is controlled by the difference in total charge between the inside and outside of the cell.
Nerve Impulse Transmission within a Neuron: Action Potential
Signals are transmitted from neuron to neuron via an action potential, when the axon membrane rapidly depolarizes and repolarizes.
Synaptic Transmission
Synaptic transmission is a chemical event which is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons.
Signal Summation
Signal summation occurs when impulses add together to reach the threshold of excitation to fire a neuron.
Synaptic Plasticity
Synapses experience plasticity by strengthening or weakening over time.
