The somatosensory cortex is responsible for processing touch and other physical sensations. When we self-administer a tickle, the brain is aware of the tickle and its location, which lowers the activation in the somatosensory cortex because the brain is anticipating and predicting the sensation. Conversely, when someone else tickles us, the brain is not aware of the location or timing, resulting in a stronger activation in the somatosensory cortex. Therefore, choice A is the best choice.
