| Abstract(in English) | The neurons in the motor cortex show lateralization depending on the arm to use. To investigate if local field potential (LFP) oscillations change with contralateral and ipsilateral arm use, we analyzed the power of LFP in supplementary motor areas (SMA) and pre-SMA while animals performed a delayed-response arm use task. LFP power changed with the laterality of the arm use, but that it was frequency dependent. Specifically, power in the gamma range increased during contralateral arm use, while beta power increased with ipsilateral arm use. Subsequently, we confirmed that the frequency-dependent laterality was true also for the memory-guided trials. Our data therefore suggest that lateralized movement is executed by gamma oscillations and unit activities in the contralateral hemisphere, and is modulated by beta frequency activities in the ipsilateral hemisphere. |
