Tactile Illusions
Examples of tactile illusions include phantom limb, the thermal grill illusion, the cutaneous rabbit illusion and a curious illusion that occurs when the crossed index and middle fingers are run along the bridge of the nose with one finger on each side, resulting in the perception of two separate noses. Interestingly, the brain areas activated during illusory tactile perception are similar to those activated during actual tactile stimulation. Tactile illusions can also be elicited through haptic technology. These "illusory" tactile objects can be used to create "virtual objects".

Famous quotes containing the word illusions:
“When Wilson got upon his legs in those days he seems to have gone into a sort of trance, with all the peculiar illusions and delusions that belong to a pedagogue gone mashugga. He heard words giving three cheers; he saw them race across a blackboard like Mexicans pursued by the Polizei; he felt them rush up and kiss him.”
—H.L. (Henry Lewis)
