Sensorimotor rhythm
Sensorimotor rhythm
Sensorimotor rhythm (SMR) (pronunciation: sen-so-ri-mo-tor rhythm) is a type of brain wave that is observed in the sensorimotor cortex, the area of the brain responsible for coordinating voluntary movements.
Etymology
The term "sensorimotor" is derived from the words "sensory" and "motor", referring to the sensory and motor functions of the brain. The term "rhythm" refers to the rhythmic pattern of these brain waves.
Definition
Sensorimotor rhythm is a type of brain wave that is observed in the sensorimotor cortex, the area of the brain responsible for coordinating voluntary movements. It is typically observed in the frequency range of 12-15 Hz, and is associated with a state of relaxed alertness and readiness for action.
Function
The primary function of the sensorimotor rhythm is to regulate the activity of the sensorimotor cortex. It is thought to play a role in the inhibition of motor activity, meaning that it helps to prevent unnecessary or unwanted movements. It is also associated with a state of relaxed alertness and readiness for action.
