The collodion-fixed fibers were attached over the left hemisphere of the subject so as to symmetrically match the standard probe (Fig. 2). Fig. 2 and 3 are obtained using Atlasviewer, part of the HOMER2 NIRS processing package.
Probe arrangement in epilepsy patients for subject 1 (left, one side), subject 2 (right, symmetrical on both sides). The red and blue numbers indicate the position of sources and detectors respectively. The yellow lines indicate a source-detector pair, or channel.

Fig. 2 and 3 are obtained using Atlasviewer, part of the HOMER2 NIRS processing package. The positioning of the optical probes was decided based on the medical history of patient, so as to maximize the likelihood that NIRS measurements would be sensitive to the epileptic focus (Fig. 3).
