A Novel One-Day Learning Procedure for Mice.

ABSTRACT

Current preclinical cognitive assessments are highly time intensive, with lengthy assessment procedures. In this regard, a single-day assay that focuses just on assessing learning behavior in a time-effective and relatable manner would be of value. This article describes the box maze as a short-term behavioral procedure to measure learning in mice. The protocol consists of allowing mice to explore an enclosed space that has eight holes. One of these holes leads to a tunnel that connects to an escape cage, and the latency to enter this escape hole is recorded for each mouse. Mice are tested four times within a single day, and the decrease in escape latency over time is used as a measure of learning. Age is a factor that affects escape latency in the box maze. Hence, the box-maze procedure is proposed as an efficient test to probe aging and aging intervention-related research questions. © 2020 by John Wiley & Sons, Inc.
