time to first movement outside a discrete space in an experimental apparatus time to first movement into the dark chamber of a passive avoidance apparatus 2025-07-29T12:05:06Z CMO:0004109 This is a measurement of the time it takes for a subject in a passive avoidance apparatus to move away from the lighted (safe) chamber to the dark (aversive) chamber after training with a noxious stimulus in the dark chamber. The passive avoidance test is a behavioral assay aiming at measuring long-term memory and emotional learning in rodents. The latency time it takes before the subject visits the dark chamber serves as an index of emotional memory.
