Posture influences motor imagery: an fMRI study.
Motor imagery is widely used to study cognitive aspects of the neural control of action. However, what is exactly simulated during motor imagery is still a matter of debate. On the one hand, it is conceivable that motor imagery is an embodied cognitive process, involving a simulation of movements of one's own body. The alternative possibility is that, although motor imagery relies on knowledge ...
متن کاملMotor imagery in mental rotation: an fMRI study.
Twelve right-handed men performed two mental rotation tasks and two control tasks while whole-head functional magnetic resonance imaging was applied. Mental rotation tasks implied the comparison of different sorts of stimulus pairs, viz. pictures of hands and pictures of tools, which were either identical or mirror images and which were rotated in the plane of the picture. Control tasks were eq...
متن کاملAnalysis of Brain Activation during Motor Imagery Based on fMRI
⎯Brain activation during motor imagery (MI) has been studied extensively for years. Based on studies of brain activations of MI, in present study, a complex finger tapping imagery and execution experiment is designed to test the brain activation during MI. The experiment results show that during MI, brain activation exists mainly in the supplementary motor area (SMA) and precentral area where t...
متن کاملMotor imagery of complex everyday movements. An fMRI study.
The present study aimed to investigate the functional neuroanatomical correlates of motor imagery (MI) of complex everyday movements (also called everyday tasks or functional tasks). 15 participants imagined two different types of everyday movements, movements confined to the upper extremities (UE; e.g., eating a meal) and movements involving the whole body (WB; e.g., swimming), during fMRI sca...
متن کاملInvestigation of fMRI neurofeedback of differential primary motor cortex activity using kinesthetic motor imagery
Functional MRI neurofeedback (fMRI NF) is an emerging technique that trains subjects to regulate their brain activity while they manipulate sensory stimulus representations of fMRI signals in "real-time". Here we report an fMRI NF study of brain activity associated with kinesthetic motor imagery (kMI), analyzed using partial least squares (PLS), a multivariate analysis technique. Thirteen healt...
