Understanding how mood states are linked to brain activity and behavior

Official title: Behavioral and Neuronal Correlates of Human Mood States

Funded at Stanford University · NIH-10982498 · Data updated 2026-11-12

This study is looking at how your speech and facial expressions can help track your mood in real-time, especially for people getting ready for epilepsy surgery, so that doctors can better understand and support your mental health.

Who could benefit from this research

Could help

Ideal candidates for this research are patients with epilepsy who also have major depression and are undergoing surgical treatment.

Less likely to help

Patients without epilepsy or those who do not have comorbid major depression may not benefit from this research.

What this research studies

This research investigates how observable behaviors, such as speech patterns and facial expressions, can provide continuous and objective measures of mood. By using advanced video technology, the study aims to correlate these behaviors with brain activity in patients undergoing epilepsy surgery. Participants will have their mood assessed frequently while their audio-visual data is collected, allowing researchers to develop a model that predicts mood changes based on these behaviors. The goal is to improve mental health treatment by providing more accurate and timely assessments of mood.

Why it matters

Potential benefit: If successful, this research could lead to better monitoring and treatment of mood disorders, enhancing patient care.

How similar studies have gone: Other research has shown promise in using behavioral indicators to assess mood, but this approach is innovative in its use of video-derived data in a clinical setting.
