Synaptic Signaling

Definition

Synaptic signaling is an interaction between two nerve cells where an electrical signal or neurotransmitter molecule released from one neuron will stimulate another neuron, allowing for rapid transmission of information across synapses.

Analogy

Consider synaptic signaling as passing notes in class. One student (neuron) writes down some information (neurotransmitter) on paper and passes it over to their friend (another neuron). The friend then reads and understands what was written down.

Related terms

Neuron: A specialized cell transmitting nerve impulses; essentially, neurons are the 'note-passers' in our analogy.

Synapse: The junction between two neurons where information transfer occurs; think about it as the space across which the note must be passed.

Action Potential: This is the electrical signal that typically moves from the cell body down the axon of a neuron. It's like the decision to write and pass a note.
