Nānā mākou i ka hopena o ka hoʻohana nui ʻana o ka Pūnaewele i ka manawa – ke ʻano pinepine o ka electroencephalogram e ka wavelet i hoʻololi a me ka non-negative matrix factorization (NMF). Loaʻa nā hiki e pili ana i ka hanana (ERP) o nā kumuhana maʻamau a me nā mea hoʻohana pūnaewele he nui i ka hoʻohana ʻana i ka hoʻokolohua oddball paradigm. Ua noi mākou i ka nalu i hoʻololi ʻia a me nā hanana spectral e pili ana i ka hanana i ERP i mea e huki ai i nā helu manawa-pinepine. Ua hoʻopau ʻia nā helu helu hōʻike hōʻike F o nā manawa manawa pinepine i nā ʻelua e NMF. ʻO ka hoʻohana nui ʻana o ka Pūnaewele i hopena i kahi hōʻemi nui o nā amplitude P300 (P <0.05) a me kahi piʻi nui o ka latency P300 (P <0.05) i nā uila uila āpau. ʻO ka hopena nui o ka hoʻohana nui ʻana i ka Pūnaewele ma ka oscillation gamma ma ∼300ms ma hope o nā stimuli ma 40-50Hz ma ka waena waena o parietal. No laila, hōʻike kēia mau ʻike i ka hoʻohana nui ʻana o ka Pūnaewele i ka coding ʻike a me ka hoʻopili ʻana i ka lolo.
