Executive Industry Relevance

Concurrent EEG and LFP recordings in anesthetized rats enable high-resolution mapping of cortical network activity, supporting mechanistic de-risking in early CNS drug discovery. This dual-modality approach enhances predictive confidence in target validation by correlating surface and local neuronal responses to controlled sensory stimulation. Integrating these electrophysiological readouts informs portfolio decisions at the discovery and preclinical interface.
