A
lzheimer’s disease (AD) is a progressive neurodegenerative disease that manifests as memory loss, cognitive dysfunction
and dementia. Spatial learning and memory of AD rodent models is often assessed via navigational cues in mazes, most
popular are the Morris water maze and the dry-land Barnes maze. Improved performance over sessions or trials is thought
to reflect learning and memory. The Barnes maze is considered less stressful compared to water mazes and also useful for
rodent models with minor motor deficits. The Barnes maze is a circular platform top with several holes equally spaced around
the perimeter edge. Symptomatic animals of two transgenic AD mouse models were analyzed in the Barnes maze test using
a hippocampal learning protocol. Barnes maze results were analyzed for escape latency, speed, distance traversed, number of
target entries, and the abidance in the target quadrant during the probe trial. Data of different models were compared. Our
data show that the dry-land behavioural test apparatus of the Barnes maze is a valuable tool to analyse learning and memory
deficits of different rodent AD models. This method might be an effective alternative to the Morris water maze while causing
less stress to the animals.
