Synaptic potentials effect the release of transmitter from locust nonspiking interneurons.

An excitatory synaptic potential in a local nonspiking interneuron of a locust is able to effect the release of chemical transmitter. The consequence is that a discrete inhibitory synaptic potential is evoked in an identified postsynaptic motoneuron. These local interactions between interneurons and motoneurons are of behavioral significance in that they ensure the correct operation of a resistance reflex.
