老鼠的胡须像欧拉螺旋一样自然弯曲。本文对15只大鼠523根胡须的内在形态进行了分析研究。我们表明,在大鼠的脸颊上的胡须,其中每一个有不同的长度和形状的品种,可以描述一个简单的数学方程,使每个胡须表示为欧拉螺旋线上的一个间隔。当一只大鼠的所有有代表性的触须肌曲线被组装在一起时,它们跨越从欧拉螺旋的一个卷曲域延伸到另一个卷曲域的间隔。我们还发现,每根触须与触须尖端形成的球形虚拟表面的法线形成几乎相同的47度角,这构成了大鼠的触觉感觉护罩或“搜索空间”。深入了解增长,形式和功能之间的关系的线性曲率模型的影响进行了讨论。
Rat whiskers curve naturally as Euler spirals. This paper reports on an analytical study of the intrinsic shapes of 523 whiskers from 15 rats. We show that the variety of whiskers on a rat’s cheek, each of which has different lengths and shapes, can be described by a simple mathematical equation such that each whisker is represented as an interval on the Euler spiral. When all the representative curves of mystacial vibrissae for a single rat are assembled together, they span an interval extending from one coiled domain of the Euler spiral to the other. We additionally find that each whisker makes nearly the same angle of 47∘ with the normal to the spherical virtual surface formed by the tips of whiskers, which constitutes the rat’s tactile sensory shroud or “search space.” The implications of the linear curvature model for gaining insight into relationships between growth, form, and function are discussed.
