“…Using ME as control task, we confirmed that MI shares overlapping neural structures in the primary motor cortex. In accordance with well-known findings in fMRI and EEG, (Beisteiner, et al 1995;Buccino, et al 2006;Filimon, et al 2007;Grèzes and Decety 2001), we observed inter-condition differences with lower levels in the amplitude during MI tasks compared to ME. This fact may be explained by the simulation hypothesis, i.e.…”

Motor imagery in response to fake feedback measured by functional near-infrared spectroscopy AbstractThe objective of this study was to describe brain oxygenation patterns during motor imagery (MI) in response to feedback using functional near-infrared spectroscopy (fNIRS). fNIRS was recorded over the primary motor cortex in 15 healthy subjects using a right hand motor task during four fake feedback conditions: MI without Feedback (MI(0)), MI with positive (MI(+)) and negative Feedback (MI(-)) and during actual movement execution (ME) as control task.Behavioral data were collected using the Edinburgh Handedness Inventory (EHI) and TheKinesthetic and Visual Imagery Questionnaire (KVIQ-10).We observed inter-condition differences and inter-subject variability in signal amplitude with larger O 2 Hb concentration changes both in response to MI(+) (0.154 ± 0.067 μmol/l) and MI(-) (0.129 ± 0.074 μmol/l) as compared to MI(0) (0.109 ± 0.024 μmol/l) and ME (0.210 ± 0.013We present fNIRS data of MI performance in response to different feedback conditions indicating that there exist distinct oxygenation patterns. These data may contribute to the development of fNIRS controlled feedback systems.

“…The discovery of the mirror neuron system was made by Rizzolatti et al 12) in a monkey study of the ventral premotor cortex (area F5), and the existence o f a s i m i l a r s y s t e m i n h u m a n s h a s s i n c e b e e n demonstrated 13,14) . Those studies revealed that the motor system in the brain is activated when individuals observe the actions of others, and therefore, observation of actions as well as motor imagery is expected to be applicable to rehabilitation 15) .…”

Abstract.[Purpose] The aim of this study was to investigate whether the performance of a combination of observation and motor imagery of chopstick use (complex task) increased corticospinal excitability more than the performance of observation alone. [Subjects and Methods] We recruited 10 healthy subjects with no history of neurological diseases. Corticospinal excitability was assessed with the participants seated in front of a computer screen performing three tasks: (1) control, the subjects were instructed to relax; (2) OBS, the subjects were told to observe an action depicted in the video, and (3) OBS + IMG, the subjects were told to imagine performing an action depicted in a video. During tasks (2) and (3), a video was displayed on the computer screen showing the hand of a male subject using chopsticks to move small items of food from one dish to another (first person perspective). Imagery was performed kinesthetically.[Results] The MEP amplitude in the first dorsal interosseous was significantly increased during OBS+IMG relative to that in the control condition, but not that in the OBS condition. The MEP amplitude in the thenar muscles was significantly different between OBS and OBS+IMG. [Conclusion] These results suggest that the combination of observation and motor imagery of a complex task may be more effective than observation alone for motor rehabilitation purposes.

“…Prior to the subsequent reporting of these mirror properties (Gallese, et aI., 1996;Giacomo Rizzolatti, Fadiga, Gallese, et aI., 1996), those same researchers made an attempt to identify a similar matching system in humans (Fadiga, et aI., 1995). Since that time, much attention has been devoted to discovering a MNS in the human brain (Buccino, et aI., 2001;Buccino, Binkofski, & Riggio, 2004;Buccino, Lui, et aI., 2004;Buccino & Riggio, 2006;Buccino, Solodkin, & Small, 2006;Buccino, Vogt, et aI., 2004;Kilner, Neal, Weiskopf, Friston, & Frith, 2009;Giacomo Rizzolatti & Craighero, 2004;Giacomo Rizzolatti, Craighero, & Fadiga, 2002;Giacomo Rizzolatti, et aI., 2001;Giacomo Rizzolatti, Fogassi, & Gallese, 2008;Vogt & Thomaschke, 2007;Wilson & Knoblich, 2005 They reported that the activation of the motor areas is significantly modified by the observation of action performed by others. Gangitano, Mottaghy, and Pascual-Leone (2001), using a model performing a finger-to-thumb grasping motion as stimuli, reported that the amplitude of the motor potentials elicited by TMS were modulated by the gap between the finger and thumb across time.…”
