why cant we tickle ourselves???

Answer 1

ha! good question
Brain scientists at the University College London have pinpointed the cerebellum as the part of the brain that prevents us from self-tickling. The cerebellum is the region located at the base of the brain that monitors our movements. It can distinguish expected sensations from unexpected sensations. An expected sensation would be the amount of pressure your fingers apply to your keyboard while typing. An unexpected sensation would be someone sneaking up behind you and tapping you on the shoulder. While the brain discards the sensation of typing, it pays a lot of attention to someone tapping on your shoulder. The difference in reactions from expected to unexpected is a built-in response that probably developed in early human history to detect predators.

Although we are not able to tickle ourselves unassisted, there is a way to trick the brain by using a robot tickler. That's right. With all of the know-how of science and technology, a robot has been designed to allow people to tickle themselves. The same British scientists mentioned above have designed a machine that enables you to tickle yourself by remote control. To use the machine, a person lies on their back with their eyes shut. The robot is located near the person with a piece of soft foam attached to a plastic rod that is controlled by a remote control joystick. When the person activates the rod, the robot will react after a short delay. Even with delays as short as a fifth of a second from the time the person activates the rod until the robot tickled the person's hand, subjects have described the sensation as the same as another person tickling them. So, in a sense, you could tickle yourself with a robotic assistant.

Charles Darwin noticed that for tickling to be effective, you must not know the precise point of stimulation in advance, and reasoned that this is why you cannot effectively tickle yourself.

There have been experiments with devices that give random tickles and they work.
