Creates an opportunity to study attentional set shifting (a measure of cognitive flexibility and executive functions), by testing the ability of rodents to adapt to constantly changing rules. Especially for translational research in psychiatric medicine.
Includes 2 compartments with auto sliding doors, 3 automated stimulators (visual, tactile and olfactory), 2 nose poke holes and reward pellets. The instrument is automatically managed by a dedicated version of ANY-maze software.

Attentional set shifting is a measure of cognitive flexibility and executive functions, refering to the ability to switch between arbitrary internal rules (“cognitive-attentional sets”). The most widely used neuropsychological tasks for the
evaluation of this function in humans are the Wisconsin Card Sorting Test (WCST) and the CANTAB Intra-/Extra-Dimensional set-shifting task (ID/ED).
These tasks have been used to identify specific cognitive abnormalities in a wide range of mental disorders including autism, schizophrenia, Parkinson’s disease, obsessive-compulsive disorders, and attentiondeficit/hyperactivity disorders.
The clinical relevance and solid methodologic approach of the WCST and the ID/ED tests have attracted interest in preclinical research. Importantly, these tasks allow for the selective measurement of discriminative learning, reversal learning, and switching of attention within the same dimension (intradimensional shift [IDS]) and between different perceptual dimensions (extradimensional shift [EDS]) within the same subject. This distinction is crucial because a double dissociation or functional specialization between the lateral (in monkeys and humans)/medial (in rodents) and orbital regions of the prefrontal cortex (PFC) have been demonstrated. That is, whereas the orbitofrontal cortex is selectively involved in the reversal phases of these tasks, the lateral/medial PFC region governs the EDS stages.
In genetically modified mice with reduced catechol-O-methyltransferase activity there wasselective improvement on extradimensional shift abilities and impairment of serial reversal learning.
