Q:

Is everyone ticklish?

A:

No conclusive evidence exists to support whether everyone is truly ticklish or not. Each person has a "ticklish" response to stimuli dependent upon the sensitivity of his nervous system and other factors, but tickling the skin does not always result in laughter.

Tickling is subjective, with stimuli producing a variety of responses. Unanticipated tickling often results in laughter, while being prepared for tickling can prevent the laugh response.

Gargalesis is tickling that can produce laughter, while knismesis is tickling produced by light touch that often results in an itchy feeling.

Various studies on tickling have been carried out, with a wide array of results that explain why tickling happens, how different people respond and why self-tickling does not work.

  • Q:

    How do you become ticklish?

    A:

    The sensation of being ticklish occurs as a physiological response to unexpected touch when the somatosensory cortex and anterior cingulate cortex in the brain produce two messages via the central nervous system that combine to produce a pleasant sensation, reports Josh Clark for HowStuffWorks. The same nerves that interpret the tickling sensation also report sensations of hot, cold and pain to the brain's neurological pathways.

    Are dogs ticklish?

    A:

    Tickling is still poorly understood by science, but it doesn't appear that dogs are ticklish like humans. However, dogs do have a well-known reflex, called the scratch reflex, which triggers them to twitch a leg when touched in certain areas. This is popularly referred to as being ticklish.
