Knowledge Rules.

EmSense has created the first scalable physiological and brainwave measurement technology—providing accurate, objective, moment-by-moment analysis of how a large audience responds emotionally and cognitively to media messaging.

Based on rigorous EEG neuroscience applied to thousands of participants, our non-invasive tracking of involuntary brain, heart, and other body responses—combined with respondent-generated diagnostics—provides clients with a complete, non-biased assessment of media and message content.
