Multimodal Predictive Control in Crickets

摘要

A combination of behavioural testing and robotic modelling was used to investigate the interaction between sound localisation (phono-taxis) and optomotor following in crickets. Three hypotheses describing simple interactions - summation, gain modulation and chaining - were eliminated, leaving efference copy as the most likely mechanism. A speculative but plausible model for predicting re-afference was implemented and evaluated on a robot.
