Purposive decision-making task in mice using touchscreen operant apparatus.

Area of Science:

• Neuroscience
• Cognitive Science
• Animal Behavior

Background:

• Purposive decision-making, a key aspect of executive functioning, relies on sensory input and memory.
• Evaluating executive functioning is vital for understanding neuropsychiatric disorders and brain injuries.
• A significant gap exists in available mouse models for assessing executive functioning.

Purpose of the Study:

• To develop and validate a novel touchscreen task for assessing purposive decision-making in mice.
• To provide a new tool for investigating the neural underpinnings of decision-making processes.
• To address the lack of suitable behavioral assays for executive function in rodent models.

Main Methods:

• Mice were trained on a touchscreen task requiring them to discriminate between left and right visual cues.
• The task involved associating specific visual stimuli with correct window-touch responses.
• Performance was monitored to assess learning and decision-making accuracy based on cues and memory.

Main Results:

• Mice demonstrated a gradual acquisition of the relationship between visual cues and required actions.
• Mice achieved over 80% accuracy in correct choices, utilizing visual cues, memory, and self-knowledge.
• The task allowed for clear determination of when visual stimuli were perceived by the mice.

Conclusions:

• The developed touchscreen task is a valuable tool for assessing purposive decision-making in mice.
• This assay can facilitate research into the neural mechanisms underlying complex cognitive functions.
• The task provides a standardized method for studying executive functioning in a preclinical setting.
