Concurrent electrophysiological recording and cognitive testing in a rodent touchscreen environment.

Area of Science:

• Neuroscience
• Cognitive Science
• Animal Models

Background:

• Developing effective therapeutics for neuropsychiatric disorders is hindered by a lack of translational models.
• Touch-sensitive procedures and electrophysiological techniques are advancing animal model development.

Purpose of the Study:

• To integrate touchscreen-based cognitive tasks with electrophysiological recordings in rats.
• To develop a translational model for studying cognitive control in neuropsychiatric disorders.

Main Methods:

• Developed a rat flanker task using touchscreen stimuli.
• Performed electrophysiological recordings (local field potentials and EEG) during the task.
• Evaluated various stimuli for training efficiency and behavioral effects.

Main Results:

• Purple and green photographic stimuli facilitated efficient training and flanker interference effects.
• Visual evoked potentials (VEPs) showed stimulus-locked outcomes in both LFP and EEG recordings.
• Demonstrated the feasibility of concurrent electrophysiological recordings and touchscreen cognitive testing in rodents.

Conclusions:

• This integrated approach offers a feasible and promising method for preclinical research in neuropsychiatric disorders.
• Encourages the use of this combined methodology for future therapeutics development.
• Highlights the potential for reverse-translating human cognitive paradigms to rodent models.
