Exposure to Patterned Auditory Stimuli during Acute Stress Prevents Despair-Like Behavior in Adult Mice That Were Previously Housed in an Enriched Environment in Combination with Auditory Stimuli

Week	Increase stimulation per week (minutes; min)	Number of pieces applied in random order
First	01 to 07	8
Second	08 to 15	9
Third	16 to 21	10
Fourth	22 to 30	13
Fifth	30	48
Sixth	30	88

The week form Thursday including Saturdays and Sundays. There were three sessions each day during the dark phase. Duration of stimuli changes about one or two minutes from one session to another. We applied different works for each week. This difference corresponded to at least 80% of the works. All PAS works were accelerated 200% in tempo and frequency as is indicated in Materials and Methods.
