Understanding Tickling and the Brain

The video explores why people can't tickle themselves, focusing on the brain's role in anticipating self-tickling and the sense of agency. It discusses experiments involving REM sleep and body illusions to see if self-tickling is possible. Despite these efforts, self-tickling remains elusive, highlighting the brain's control over self-induced sensations. The video concludes by promoting further learning on the human brain through SciShow Psych.
