Neurons pass signals across microscopic synaptic gaps
Electrical impulses trigger neurotransmitter release to communicate across synapses
Brain function relies on electrical impulses travelling down neurons until they reach axon terminals at synaptic clefts. There, electrical signals trigger the release of chemical neurotransmitters like dopamine and serotonin across a 20-nanometre gap to post-synaptic receptors. This chemical bridge enables complex neuronal circuit processing throughout the nervous system.

Neurons pass signals across microscopic synaptic gaps: the short answers
- Where does this come from, and can I check it?
- Electrical impulses trigger neurotransmitter release to communicate across synapses. The figure is taken from Smithsonian, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a science fact?
- Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
