Definition of bouton in English:

bouton

noun ˈbuːtɒnbo͞oˈtôn

Anatomy

An enlarged part of a nerve fibre or cell, especially an axon, where it forms a synapse with another nerve.
〔剖〕疖，小结（哑铃状脓肿）
Example sentencesExamples
- Most synaptic boutons in the mammalian central nervous system are too small to be investigated directly with electrophysiological tools on the single synapse level.
- When postsynaptic receptors are saturated, a quantum of synaptic current corresponds to the response evoked in a single synaptic bouton.
- There is an estimated total of 30000-50000 boutons of different types across the entire surface.
- In this case, spillover is limited to the postsynaptic sites under a single synaptic bouton, and occupancy is likely to vary across sites.
- To determine the latter, methods that stain the terminal boutons are used.

Origin

1930s: from French, literally 'button'.
