electroencephalograph

word of the day.

electroencephalograph (EEG), 中文叫做「腦波儀」或是「腦電描記器」。(腦波儀耶，突然想到倪匡的小說)

“Electroencephalography is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed on the scalp or, in special cases, subdurally or in the cerebral cortex. The resulting traces are known as an electroencephalogram (EEG) and represent an electrical signal (postsynaptic potentials) from a large number of neurons.” — from Wikipedia

洪蘭在2005年11月的科學人寫了一篇相關的文章。

老弟的強者學長自己用家用電器克難地做了一個EEG出來，如果很用力的想，電腦可以拼出字來，蠻好玩的。有錄影有真相。

也許有一天我可以把便宜自製EEG和某個HCI project連起來也不一定。
