摘要：
The present invention provides a method for making determinations on or classifying the pain of an estimation subject on the basis of the brainwaves of the estimation subject. This method includes: (a) a step for stimulating the estimation subject at a plurality of levels of stimulation intensity； (b) a step for acquiring brainwave data for the estimation subject that corresponds to the stimulation intensities or for acquiring analysis data for the brainwave data； (c) a step for extracting a brainwave feature quantity from the brainwave data or the analysis data； (d) and a step for plugging the feature quantity into a Sparse model analysis, making the feature quantity approach a quantitative level and/or a qualitative level for pain, and estimating or making a determination on a pain level. The present invention also provides a method for making determinations on or evaluating pain, the method incorporating a step for comparing all or a portion of brainwave data or analysis data for the brainwave data from the 2,000 msec following the earliest of an induced brainwave component, an initial-event-related voltage component, and 250 msec after a target stimulus has been applied with brainwave data or analysis data for the brainwave data from after the same amount of time after a reference stimulus has been applied.
