Fig 1.
Experimental setup, visual feedback and experimental conditions.
(A) Subject in the MR scanner wearing a data glove and grasping the tube with the right hand. Visual feedback provided via mirror projection from a monitor. (B) Visual feedback consisted of the starting position (light-blue circle), movement cursor (skin coloured circle) and target (red circle) on grey background. (C) cursor feedback, (D) point light feedback, (E) cartoon hand feedback, and (F) virtual hand feedback.

Reaction time and standard error of the four types of visual feedback.
Cursor (red), point light (green), cartoon hand (cyan), and virtual hand (violet) conditions. Asterisks illustrate significant differences between conditions (p < 0.05).

Blink rate and average duration of fixation for the four movement and the four observation conditions.
Mean and standard error of A number of blinks per trial and B duration of fixation. Cursor (red), point light (green), cartoon hand (cyan), and virtual hand (violet) visual feedback.
