Abstract
The ability to perform movements is vital for our daily life. Our actions are embedded in a complex environment where we need to deal efficiently in the face of unforeseen events. Neural oscillations play an important role in basic sensorimotor processes related to the execution and preparation of movements. In this review, I will describe the state of the art regarding the role of motor gamma oscillations in the control of movements. Experimental evidence from electrophysiological studies has shown that motor gamma oscillations accomplish a range of functions in motor control beyond merely signaling the execution of movements. However, these additional aspects associated with motor gamma oscillation remain to be fully clarified. Future work on different spatial, temporal and spectral scales is required to further understand the implications of gamma oscillations in motor control.
Highlights
The ability to perform movements is vital for our daily life
The motor system constitutes all those processes involving the movement of the muscles and the neural systems advocated to the control of the muscles
The brain circuits associated with movements converge on the primary motor cortex (M1 or Brodmann area 4) and signals are sent through the spinal cord to the muscles so motor commands are executed
