MU rhythm is primarily recorded in which electrode region?

MU rhythm, also known as the mu wave, is primarily associated with the sensorimotor cortex, which is located in the lateral aspects of the brain. Specifically, this rhythm is typically recorded from the C3 and C4 electrode placements, corresponding to the left and right hemisphere representation of the sensorimotor areas. This rhythm is most prominent when individuals are at rest and is often correlated with motor activity and motor planning, reflecting neural mechanisms involved in the control of movement.

The placement of electrodes at C3 and C4 allows for optimal detection of the mu rhythm, as these regions are directly above the primary motor cortex where the MU rhythm is generated. Additionally, it is important to note that while other electrode regions (such as O1/O2, F3/F4, and P3/P4) are used for different types of brain activity monitoring (like visual or frontal activity), they do not target the specific cerebral structures associated with the mu rhythm.
