Summary
This study details an upgraded automated Operon ID/ED task for mice, enhancing cognitive flexibility research. The improved system aids in preclinical drug testing and genetic screening for conditions like schizophrenia.
Area of Science:
- Neuroscience
- Cognitive Science
- Animal Behavior
Background:
- Attentional set shifting assesses cognitive flexibility and executive functions.
- The Wisconsin Card Sorting Test (WCST) and CANTAB Intra-/Extra-Dimensional set-shifting task (ID/ED) are standard human assessments.
- The automated Operon ID/ED task is a valuable preclinical tool for drug testing and genetic screening.
Purpose of the Study:
- To describe an upgraded, commercially available automated two-chamber Operon ID/ED task for mice.
- To provide a detailed protocol for using this upgraded task to study attentional set shifting.
- To offer guidance on using the associated ANY-maze software for adaptability.
Main Methods:
- Utilized an upgraded automated two-chamber Operon ID/ED system for mouse behavioral testing.
- Employed a detailed step-by-step protocol for mouse preparation and testing.
- Included a manual for the ANY-maze software to facilitate task adaptation.
Main Results:
- The upgraded Operon ID/ED task allows for the study of attentional set shifting across two or three dimensions (lights, odors, textures).
- A comprehensive guideline for operating the equipment and paradigm is provided.
- The system is designed for effective preclinical drug testing and genetic screening.
Conclusions:
- The upgraded Operon ID/ED task offers a robust and adaptable preclinical model for cognitive flexibility research.
- This tool has direct translational relevance for understanding human cognitive disorders like schizophrenia.
- The provided protocol and software manual ensure comprehensive usability for researchers.

Operons
53.1K
Prokaryotes can control gene expression through operons—DNA sequences consisting of regulatory elements and clustered, functionally related protein-coding genes. Operons use a single promoter sequence to initiate transcription of a gene cluster (i.e., a group of structural genes) into a single mRNA molecule. The terminator sequence ends transcription. An operator sequence, located between the promoter and structural genes, prohibits the operon’s transcriptional activity if bound by...

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
