Conditioning of an autonomic response in Crustacea
Reports on experience-dependent changes in invertebrate autonomic function are few. In the crab Chasmagnathus, repeated presentations of a visual danger stimulus (VDS) elicit long-term cardiac adjustments. Although these changes can be explained in terms of an associative process, they do not necess...

Reports on experience-dependent changes in invertebrate autonomic function are few.

In the present work, we investigated anticipation of the cardio-inhibitory response (CIR) after classical conditioning.
