| Outline of Final Research Achievements |
The compensational recovery of the escape direction in the wind-evoked escape behavior in the cricket, Gryllus bimaculatus, is guided by the self-generated wind during walking. The relationship between the delay and duration of artificial self-generated winds for the compensational recovery was investigated. It was revealed that the two parameters of the stimulus air current, i.e., the delay and duration, have a trade-off relationship for the completion of the compensational recovery of the escape direction.
Activities of some descending neurons in the ventral nerve cord and those of leg muscles showed a strong correlation, i.e., activities of descending neurons increased proportionally to the activity of leg muscles. From the result, it is thought that such descending neurons are good candidates that carrying efference copy signals that considered to be essential for the compensational recovery of the escape direction.
