Experimental design. After around six weeks in their respective housing conditions, rats underwent a contextual fear conditioning procedure. Immediately after the reactivation session (day 2), saline (SAL) or midazolam (MDZ) was administered. One week after the end of the conditioning protocol, half of the rats (4 from each group) were exposed to a novel context to assess locomotor activity. Standard rats were first housed in large (non-enriched) cages of 9 rats (equal in size to the EH cage depicted in the left picture) and then transferred to smaller cages of 4 rats per cage at PND 58 (middle picture).
