The Choice of a Violent Suicidal Means: a MRI Study With Computational Modeling of Decision-making

The computerized pressure algometer, AlgoMed (Medoc, Ramat Yishai, Israel), will be used for mechanical pain stimulation to assess information about pain threshold and tolerance. A constant rate of pressure is delivered by the examiner, and the pressure is recorded in Kilopascal (kPa). The stimulation will be applied between the medial and distal joints of the phalanges of the dominant hand.
