Sensori-motor and Perceptual Functions of the PPC.

In the experiences 1 and 2, the participant needs to point different visual targets (LED) in the dark.

In the experience 3, a tactile stimulation is applied to the middle finger of the 2 hands. The participant needs to indicate into a microphone when he feels the stimulation.

Target dots or visual images are presented on a computer screen. The participant is required to point to the targets or to react as soon as possible by pressing a response button when they are detected.
