An operational definition of synergy is introduced and developed based on the uncontrolled manifold hypothesis. Synergies are described for a variety of tasks and subpopulations. Possible neurophysiological mechanisms and models of synergies are discussed. 606 $aHuman mechanics 606 $aBiomechanics 606 $aSystem theory 606 $aMovement$xphysiology$3(DNLM)D009068Q000502 606 $aSystems Theory$3(DNLM)D013598 606 $aBiomechanical Phenomena$3(DNLM)D001696 606 $aMotor Activity$xphysiology$3(DNLM)D009043Q000502 606 $aNeurophysiology$xmethods$3(DNLM)D009482Q000379 615 0$aHuman mechanics. 615 0$aBiomechanics. 615 0$aSystem theory. 615 12$aMovement$xphysiology. 615 12$aSystems Theory. 615 22$aBiomechanical Phenomena. 615 22$aMotor Activity$xphysiology. 615 22$aNeurophysiology$xmethods. 676 $a612.7/6 700 $aLatash$b Mark L.$f1953-$01811347 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910961841903321 996 $aSynergy$94363162 997 $aUNINA
