Abstract
The discovery of brain potential that preceded voluntary movement by Drs. Kohhuber and Deecke in 1964 with the identification of each component of the MRCP (movement-related-cortical potential) by Dr. Shibasaki in 1980 opened the door of motor control research. Although the exact origin of MRCP in the motor cortex has long been unknown, investigating MRCP as the epilepsy presurgical evaluation with electrocorticography confirmed the role of MRCP in the primary and supplementary motor area (Ikeda et al., 1992 Brain, Ohara et al., 2000 Brain), expanding the clinical applications. Additionally, the concept of event-related synchronization/de-synchronization (ERS/ERD) with a time-frequency analysis established by Pfurtscheller was highly appreciated. Along this line, multi-spectrum intrinsic brain activities with a different spectral range, very slow potentials (MRCP) to high-frequency activity (ERS and ERD), allow us to advance the accuracy of systematic brain mapping (Neshige et al., Clin Neurophysiol 2018) and developed the scoring system to identify the primary and negative motor cortices (Neshige et al., Epilepsia 2019). Multi-spectrum intrinsic brain activity is reasonable, further implacable for the future design of motor physiology investigation. This study has been presented to the Annual Meeting of the Japanese Clinical Neurophysiology Society, and an abstract has appeared in its proceedings.
