| From a screen of 24,000 mutagenized flies, 17 mutants with presynaptic defects in synaptic transmission were recovered. |
| Depolarization of the presynaptic membrane causes release of acetylcholine into the synaptic cleft. |
| A variety of experiments indicate that single synaptic connections exhibit a broad distribution of presynaptic release probabilities. |
| Such tendon jerks are tested as part of a routine neurological examination, to assess the state of synaptic connections. |
| But this is not to suggest that Hebb's influence was just his postulates related to synaptic change. |
| When postsynaptic receptors are saturated, a quantum of synaptic current corresponds to the response evoked in a single synaptic bouton. |
