Subject reported that every now and then she'd press the wrong button by mistake. Subject stayed alert and awake throughout the task, but said it was really long." sub-015 24 1979 M "P6 and P8 looked open but they weren't so we stopped eeg, then pressed record again and eeg was almost solid noise, tried regrounding box but nothing worked, then spontaneously it got better ten minutes later." sub-016 19 1984 M "Tape added to electrical shielding on cord near scalp of scalp cap to insulate it from grounding electrical signals from the occipital and parietal areas, frontals shift in and out of spikeyness, short2 frontals better/good in the beginning, eyes- graph shifts up and down a lot for frontals, short #3- good" sub-017 19 1984 M EEG looks good sub-018 20 1983 F "Subject was pretty tired, channel p04 was noisy and off scale during the first EEG recording" sub-019 21 1982 F "All channels are clean except frontals, frontal noises due to muscles controlling eyes for if she closes them or looks down the noise goes away, subject stated task was long and boring" sub-020 19 1984 F "Clean eeg for the most part, subject said task was fun" sub-021 22 1981 M "For second recording P2, P3 were flat lining so we pushed in connectors at input board, and the problem was resolved; for the third recording H8 was wandering; subject says strategy was verbal rehearsal" sub-022 25 1978 M "Subject reports that he was correct on most trials, his strategy was to either repeat the letters to himself or makes a sentence; for the first recording we forgot to ground headbox to amp so there is a lot of 60Hz noise; much better after grounding in second recording, otherwise eeg is very stable, cut second recording short because FC2 was bad and needed gel, recording 4 had really good EEG, during recording 3 F6 started getting noisy so added gel, during recording 4 F6 wasnoisy again, subject usually takes a lot of time between trials" sub-023 25 1978 M n/a sub-024 19 1984 n/a n/a
