Itch is... uncomfortable. We've all been there before, one motivated mosquito takes a bite out of you, and you are left with an itchy red spot for a few days that only scratching can temporarily relieve. Have you ever wondered how that sensation is transferred to the brain and processed? How about why pain, like pressing really hard on that mosquito bite makes the itching go away. If the answer to any of these questions is YES, come and take a listen to learn a little bit more about what's happening upstairs!
