The suppression of the μ rhythm during the creation of imagery representation of movement.
Summary of "The suppression of the μ rhythm during the creation of imagery representation of movement."
The aim of this study was to answer the following question: are there differences between the attenuation of μ rhythms, recorded with EEG in the parietal area during observation of movement and the creation of its imaginative representation? In addition, we checked the extent to which the μ rhythm suppression depends on whether the observed and the imagined movement is performed by a human or is artificial. As a result of the experiment a significant difference in μ rhythm suppression between the conditions "Observation," "Imagery," and "White noise" was recorded. It did not matter whether the motion was carried out by a human being or performed by a machine. The results are discussed in the light of findings which relate to the mirror neuron system.

Medical and Biotech [MESH] Definitions
Imagery (psychotherapy)
The use of mental images produced by the imagination as a form of psychotherapy. It can be classified by the modality of its content: visual, verbal, auditory, olfactory, tactile, gustatory, or kinesthetic. Common themes derive from nature imagery (e.g., forests and mountains), water imagery (e.g., brooks and oceans), travel imagery, etc. Imagery is used in the treatment of mental disorders and in helping patients cope with other diseases. Imagery often forms a part of HYPNOSIS, of AUTOGENIC TRAINING, of RELAXATION TECHNIQUES, and of BEHAVIOR THERAPY. (From Encyclopedia of Human Behavior, vol. 4, pp29-30, 1994)
Research Embryo Creation
The creation of embryos specifically for research purposes.
Circadian Rhythm
The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
Circadian Rhythm Signaling Peptides And Proteins
A broad category of proteins that regulate the CIRCADIAN RHYTHM of an organism. Included here are proteins that transmit intracellular and intercellular signals in a chronological manner along with proteins that sense light and time-dependent changes in the environment such as the PHOTOPERIOD.
Movement
The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.
