Touchscreen-based Visual Discrimination and Reversal Tasks for Mice to Test Cognitive Flexibility.

Abstract

Reversal learning can be used to examine deficits in cognitive flexibility, which have been linked to a number of neuropsychiatric disorders including schizophrenia and addiction. However, methods of examining reversal learning have varied substantially between species. Touchscreen technology has allowed researchers to explore cognitive deficits with a platform that is translatable across rodents, non-human primates and human subjects. Here we describe a method for measuring visual discrimination and reversal learning in mice using automated touchscreen-based operant chambers.
