Action Potential:An electrical impulse or spike in voltage generated by a neuron when it receives enough stimulation, which is crucial for signal transmission.
Neurotransmitters:Chemical messengers that transmit signals between neurons by binding to specific receptor sites on the receiving neuron.
Excitatory and Inhibitory Signals: Excitatory signals increase the likelihood of a neuron firing, while inhibitory signals decrease this likelihood. Both are essential for maintaining balance in signal transmission.
