Signal Transmission

Definition

Signal transmission refers to how information is communicated within and between neurons through electrical impulses and chemical messengers called neurotransmitters.

Related terms

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.
