How do we sense temperature?

<p>One of my favourite things to learn in high school chemistry was how temperature worked&mdash;the average kinetic energy of substances being responsible for how hot or cold we might feel something to be. This was simple enough. Fast molecules that bump a lot = hotter. Slow molecules that don&rsquo;t bump as often = colder. But that doesn&rsquo;t exactly explain how our brain can sense and relay information about the temperature of a substance. When you pick up an ice cube, how does your brain know what you&#39;re touching is cold? How do we turn that measure of kinetic energy into signals that we can regularly identify as cold?</p> <p>That&rsquo;s what I&rsquo;m aiming to explain today, and having taken a course in cellular and molecular biology, this has only just started to make sense to me.</p> <p><a href="https://medium.com/scientia-blog/how-do-we-sense-temperature-71d073810fa0"><strong>Visit Now</strong></a></p>
