腦電圖分析
腦電圖分析(粵拼:nou5 din6 tou4 fan1 sik1;英文:EEG analysis)係指運用訊號處理同電腦科技嚟由腦電圖(EEG)數據嗰度獲取資訊嘅過程:腦電圖會俾出一大柞「邊個邊個時間點,個頭邊個邊個位嗰度量度到幾多微電壓」嘅數據,跟手研究者就會想對呢啲數據進行分析,由數據嗰度得出能夠描述研究緊嘅現象嘅數學模型[1],以及將啲數據轉化成有用嘅資訊;研究者可以對某段時間之間個頭某個位嘅微電壓進行分析,嘗試將得到嘅量度拆開變成幾個腦電波(brainwave),再睇吓邊個頻率嘅腦電波活動最勁,而呢樣資訊會講到有用嘅嘢俾研究者聽,例如如果某個腦區喺某段時間當中嘅 delta 波(簡單啲講就係一種反映低活動嘅腦電波)活動零舍勁,噉可能表示嗰個腦區受咗損[2][3]。
