Recording of Local Field Potential from Both Hemispheres of the Mouse Brain

Executive Industry Relevance

Bilateral local field potential (LFP) recording enables comparative analysis of neural activity across brain hemispheres, supporting target validation in neuropsychiatric drug discovery. This approach provides quantitative electrophysiological readouts that help de-risk mechanistic hypotheses by revealing lateralized functional responses to pharmacological modulation. The method enhances predictive confidence in early discovery by delivering reproducible, hemisphere-specific neural activity data.
