Brain activity and the perception of self-agency while viewing a video of hand grasping

Abstract

Self-agency is the recognition of one's own movement and plays a vital role in purposeful, voluntary movement. A sense of self-agency can be elicited in individuals who view their own simple finger movements as they are projected onto a screen and aligned with their actual hand position. Here, we examined whether individuals perceived self-agency when they viewed a video of a hand grasping a wooden cylinder and whether the perception of self-agency correlated with simultaneous changes in oxy-hemoglobin in the parietal or the prefrontal cortical areas. All participants reported the perception of self-agency, which was correlated with oxy-hemoglobin increases in the right prefrontal area. We conclude that self-agency also relates to hand-held objects displayed on video.

Spelten E R et al believe that in the collective information management system of copyright information, in addition to the personal information of the obligee, the monitoring system attached to the management system will also involve the private domain of the user to some extent [ 16 ].…”

Possible effect of natural light on emotion recognition and the prefrontal cortex: A scoping review of near-infrared (NIR) spectroscopy

“…44 We perceive almost all stimuli under any circumstances; therefore, it is challenging to aggregate perception studies. To the best of our knowledge, perception of depth, 45 emotion, [46][47][48] face, 49 reward, 50,51 self-agency, 52 and time 53 have been reported. Finally, reading studies include dyslexia 54 and overt reading 55 (reading aloud).…”

Effects of Visual–Motor Illusion via Image Videos Showing Increased Exercise Intensity on the Tibial Anterior during Sit-to-Stand Movement: A Study of Healthy Participants

“…Neural activity across multiple brain regions, including increased excitability of the frontoparietal network, has been associated with VMI [ 9 , 10 , 11 ]. Furthermore, VMI may activate brain regions (i.e., prefrontal area) associated with a sense of agency (SOA) [ 19 ]. Action observation therapy (AOT), in which motor imagery is induced from visual stimuli, has also been reported [ 20 , 21 ].…”
