本文研究了双斑蟋蟀（Gryllus bimaculatus）在空气刺激下的逃逸行为。蟋蟀几乎总是远离刺激源逃跑，在最佳条件下，平均逃跑方向与刺激源成162度。更强（更高的速度）的喷气引起了大量的蟋蟀逃跑。然而，逃跑的方向变得不正确时，刺激太强。蟋蟀与双边谷物消融没有表现出任何逃避到一个空气puff，而单侧消融的响应相同的刺激与逃避。然而，单侧谷物消融动物的反应率低于完整动物。切除一侧谷核后，蟋蟀的平均逃避方向虽然仍与刺激源相反，但不如正常动物准确，在切除一侧谷核后约6天，反应率出现了有统计学意义的代偿性恢复。另一方面，需要14天才能恢复逃逸方向。调节反应速率和行为定向的信息可能在不同的神经通路中加工。
The air-puff evoked escape behavior of the cricket, Gryllus bimaculatus, was investigated. Crickets almost always escaped away from the stimulus source, in an optimal condition, the mean escape direction was 162 degrees opposite to the stimulus source. Stronger (higher velocity) air-puff elicited an escape in larger number of crickets. However, the escape direction became incorrect when the stimulus was too strong.Crickets with bilateral cereal ablation did not show any escape to an air-puff, while unilaterally ablated ones did respond to the same stimulus with an escape. However, the response rate of animals with unilateral cereal ablation was lower than that in intact animals. Although the mean escape direction of the crickets with unilateral cereal ablation was still opposite to the stimulus source, the direction was not so accurate as in intact animals.About 6 days after the unilateral cereal ablation, the response rate showed a statistically significant compensational recovery. On the other hand, 14 days were necessary for the recovery of the escape direction. Information which regulating the response rate and the behavioral orientation is likely being processed in different neural pathways.
