To focus the activity, give every session a subject.
In each session, a subject received orally either 0.5-mg risperidone, 4-mg perospirone, 33-mg quetiapine, 1.25-mg olanzapine, 50-mg chlorpromazine, 1-mg haloperidol or placebo according to a single-blind, crossover, Latin-square design.
Following the training sessions, in each test session, a subject compared a reference sound excerpt (i.e., a clean or headset recording) and a number of test sound excerpts that included an unmarked reference sound (serving as a hidden reference), a noisy reverberant sound (serving as an anchor signal), and processed versions of the same utterance.
At the start of a testing session, a subject was transported in an enclosed box to the testing room and placed into the dark section of the arena.
For each session a subject was removed from its home cage, placed in a new nest box attached to the test cage in the testing room.
At the beginning of a session, a subject was brought to the testing room in a carrying box (42 cm × 26 cm × 13 cm, l × w × h) and placed into the empty chamber for a 10-minute familiarisation period.
Moreover, all test sessions of a subject should be administered with exactly the same time period between sessions and at the same time of day.
Most subjects had pre-drug nicotine levels range from 0 to 3 ng/ml, and in only two sessions did a subject's pre-drug nicotine levels turn out to be > 9 mg/ml.
Graham said he would meet with FBI Director James Comey on Thursday to discuss the ongoing Russia investigation, and demand to know whether Sessions is a subject of the probe.
A typical example of time-frequency maps displaying significant ERD (red) and ERS (blue) in a training session (session 3) for a subject (subject 6) in the dataset is shown in Figure 6.
