Temporal determinants of olfactory long-term memory retention in the cricket Gryllus bimaculatus were studied. Elementary appetitive and aversive conditioning procedures, as well a differential procedure, applied. In conditioning, peppermint odour was paired with water reward. vanilla saline solution. an trial followed by trial. The preference crickets tested before 2 h, 1 day 4 days after training allowing to choose between or sources. Differential alone led long-lasting no significant decay from h training, but absent training. Studies using have shown (i) that four trials are sufficient cause saturated level acquisition, (ii) is successful when conditioned stimulus presented immediately 5 s onset presentation unconditioned stimulus, (iii) optimal interval 2-5 min, (iv) anaesthetic treatment CO2 given results disruption anaesthetic-resistant develops fully 20 min This study demonstrates procedure particularly effective for formation memory.
