Ticklishness can occur in many places on the body, but the most common are the ribcage, the armpit, and the sole of the foot. Tickling usually occurs in the context of intimate relationships: parents tickle their babies and small children; siblings, romantic partners, and close friends sometimes tickle each other. Some people seem to be more ticklish than others. Self-tickling is an extreme example of this phenomenon. Your brain knows that the fingers poking you in the ribcage are your own fingers, so it dials down the sensory response. How did we figure this out? Scientists at University College London began by using functional brain imaging to compare how people responded to self-tickling and tickling by another person. They found that the somatosensory cortex—the parts of the brain responsible for body sensations—had a lower response to self-tickling than to external tickling. They also observed activity suggesting that the cerebellum monitors movements and sends signals to suppress the somatosensory response when a touch is self-generated.

His career has included exploration of various " curious behaviours ", including hiccupping, yawning and farting, so why does this one stand out? In short, there is far more to tickling that you would think. As with so many other complex human behaviours, our animal cousins can help us understand what tickling is all about. There are two types of tickling, and they both have great names: knismesis and gargalesis. Knismesis is a primitive response, a slightly irritating sensation triggered by a light movement across the skin, and it is widespread. Animals need to defend their bodies against biting insects and parasites, whether that means a quick scratch or a flicked ear, and knismesis describes such a response.
