fMRI Experiments on Online Control

In most imaging studies on human perception, participants observe or give categorical responses to stimuli which are presented to them. Such experiments are called 'open loop' experiments, since the participant only perceives the stimuli passively and can not influence them. In contrast, in 'closed loop' experiments, human participants interact with the stimulus and get direct sensory feedback about their actions. This situation is very common in real life, be it balance during standing and walking, speaking, grasping something or steering a vehicle.

Imaging experiments which investigate perception and action in closed-loop situations are rare. In this project, we are interested in the cerebral representation of the different processes of the sensorimotor loop during active control. We employ a stabilization task, in which participants use a continuous response device to control an unstable visual stimulus.
