Whiskers, cats and other mammals are not covered by ดาวน์โหลด สล็อต xo sensors. But the detection is done at the base of the whisker, hidden in a tiny pores, and scientists have recently discovered more about this biological transmission method. Going into the hair follicle to look at the base of the mustache disrupts the entire setup, so the new study explores the first mechanical simulation of the whisker detection operation.Combined with the anatomical observations of mice, the simulations showed that the base of the whisker had been transformed into an 'S' shape upon touch - then this 'S' shape would push and pull certain sensor cells to tell the brain that it was born. What's up

Whisker deformation details from the study (Yifu Luo and Nadina Zweifel).The part of the whisker that activates the touch sensor is hidden within the hair follicle, so it is incredibly difficult to study," said Mitra Hartmann, a professor of biomedical engineering at Northwestern University. sayThe development of new models has given us insights into biological processes that cannot be measured directly from the experiment.While this model is a simplified version of reality and uses only a limited set of data taken from extracted rat tentacles. But it also provides scientists with useful insights into how tentacles are used to perceive their surroundings.

Research requires expertise from a wide range of sciences, including neuroscience and continuous mechanics. Part of the mechanical model involves the application of beam theory, often used in engineering and geology, to find out how all bending materials or plates interact.Here, beam theory is applied to the interaction of whisker and follicle. The team discovered that whisker deformation - in many ways, "just a deformed beam that interacts with a spring" - tended to be the same, whether it was vigorously pressing something or a passive touch. From something else Our model demonstrates consistency in the whisker deformation profile between passive contact and active swiping," said Northwestern University mechanical engineer Yifu Luo.

In other words, the same group of sensory cells responded when the whisker turned in the same direction under both conditions. Anesthetized animals While the study looked only at mice in terms of actual biological observations, the scientists thought the findings would apply to some extent to whispering mammals, although there were differences. - I use more tentacles as a local scanner. For example, more cats What's more, research could inform the development of artificial tentacles for use in robots. Antennae can act as a subtly detecting surroundings, working in a wide range of frequencies,

and that's a useful framework to copy.And while we don't have our own tentacles, the team thinks research into human exposure could benefit from this study, too. There is still much more to be discovered about how we interact with the world through this unique sensation, and the tentacle-induced 'S' bend may be seen as a new way of understanding.The sense of touch is incredibly important to almost everything we do in the world. But studying hand touch is very difficult, ”Hartmann said. "The mustache is a simple model to understand the complex and mystical nature of the touch.
