Abstract
- Mechanical and visual stimuli associated with surface waves were separated into their two components. 2. Unfed leeches responded to the mechanical component of artificially generated surface waves by swimming towards their source. 3. Leeches also responded to and orientated towards the source of the waves using visual cues derived from the same surface waves. 4. Visual stimuli elicited fewer and less accurate responses.
摘要
- 与表面波相关的机械刺激和视觉刺激被分离为两个组成部分。2. 未进食的水蛭会朝着人工产生的表面波的机械部分的源头游动，对其做出反应。3. 水蛭还会利用源自相同表面波的视觉线索，对波的源头做出反应并朝其定向。4. 视觉刺激引发的反应越来越少且越来越不准确。
