The Barnes maze is a tool used in psychological laboratory experiments to measure spatial learning and memory. The test was first developed by Dr. Carol Barnes in 1979. The test subjects are usually rodents such as mice or lab rats, which either serve as a control or may have some genetic variable or deficiency present in them which will cause them to react to the maze differently. The basic function of Barnes maze is to measure the ability of a mouse to learn and remember the location of a target zone using a configuration of distal visual cues located around the testing area. This noninvasive task is useful for evaluating novel chemical entities for their effects on cognition as well as identifying cognitive deficits in transgenic strains of rodents that model for disease such as Alzheimer's disease. It is also used by neuroscientists to determine whether there is a causative effect after mild traumatic brain injury on learning deficits (acquisition trials) and spatial memory retention (probe) at acute and chronic time points. This task is dependent on the intrinsic inclination of the subjects to escape from an aversive environment and on hippocampal-dependent spatial reference memory.

Tipicamente vengono impiegati topi o ratti che possono servire da individui di controllo oppure avere una variabilità genetica che li porterà a reagire in modo differente al labirinto. (it) |
