当将手放在沸水上方时，除了预期的热感之外，有时还会感受到压力感。目前尚不清楚这种现象的根本原因。这种体验的因果机制的潜在候选者包括蒸汽、温度、湿度和触觉感受器活动。在本文中，我们研究了这种新颖的非接触式触觉体验的基本机制。为此，我们独立测试了这种体验的各个方面。我们的结果表明，通过汗管扩张刺激默克尔细胞是这种知觉现象的主要原因。
When a hand is held above boiling water, a sensation of pressure is sometimes experienced in addition to the expected thermal sensation. The underlying cause of this phenomenon is currently unclear. Potential candidates for the causal mechanism of this experience include steam, temperature, humidity and tactile receptor activity. In this paper we investigated the underlying mechanism of this novel non-contact tactile experience. To this end, we tested separate aspects of this experience independently. Our results suggest that stimulation of Merkel cells via sweat duct expansion is the principal cause this perceptual phenomenon.
