The cockroach can reduce the amount of sensory activity received by its CNS from the cerci, paired wind-responsive appendages. This reduction is produced by medial displacement of the cerci, a movement the animal performs naturally during flying. We demonstrate here that this sensory reduction significantly reduces activity of the postsynaptic wind-sensitive interneurons in the abdominal nerve cord, cells which carry the wind information to higher centers of the nervous system. In addition, we have found that the wind-evoked activity of two identified giant interneurons that are involved in escape and locomotion behaviors, is significantly reduced by cercal displacement.
蟑螂能够减少其中枢神经系统从尾须(一对对风敏感的附肢)接收的感觉活动量。这种减少是由尾须向内侧移位产生的,动物在飞行过程中会自然地进行这种移动。我们在此证明,这种感觉减少显著降低了腹神经索中突触后风敏感中间神经元的活动,这些细胞将风信息传递到神经系统的更高中枢。此外,我们发现,参与逃避和运动行为的两个已确定的巨型中间神经元的风诱发活动,会因尾须移位而显著降低。
