(A) Sites for delivering test and sensitizing stimuli. (B| Testing and training pro- tocol. (C) Behavioral results. A single brief train (10 s) of sensitizing stimuli leads to an enhancement of siphon withdrawal elicited by stimuli to the tail. (From McClendon. Goldsmith and Byrne, in prep.) second component is a slow EPSP that can last over one minute. This slow EPSP is sufficient in some preparations to prolong the burst elicited by the first component. In addition, the slow EPSP increases the effectiveness of syn- aptic input produced by subsequent stimulation of pe- ripheral nerves. Thus, this population of pleural inter- neurons plays a modulatory role by using a conventional postsynaptic mechanism, temporal summation of excit- atory synaptic inputs. Delivery of a sensitizing stimulus activates conventional interneurons, but, in addition, a separate modulatory cir- cuit must be recruited. This circuit has not been identified. Figure 3.
