Key result
Neurostellar's multimodal wearable successfully classifies all cognitive and affective tasks versus chance.
Why the study?
Consumer wearables for mental state assessment face scepticism regarding data quality, prompting evaluation of whether a consumer-grade EEG/PPG wearable headband can reliably capture mental states.
Does Neurostellar's wearable device reliably capture mental states compared to a laboratory-standard EEG/ECG device in healthy adults?

Does Neurostellar's wearable device reliably capture mental states compared to a laboratory-standard EEG/ECG device in healthy adults?
Effect estimate: z=13.08-13.11 (Random Forest)
p-value: p=<0.001
A consumer-grade EEG/PPG wearable headband can effectively capture psychophysiological changes and track mental states in naturalistic environments.
Marigowda et al. (2025) conducted an observational in Healthy adults (n=15). Neurostellar's wearable device vs. Laboratory-standard portable EEG/ECG device was evaluated on Classification of cognitive and affective tasks using advanced multimodal features (z=13.08-13.11 (Random Forest), p=<0.001). Neurostellar's wearable device, employing advanced multimodal features, significantly classified all cognitive and affective tasks (Random Forest: z=13.08-13.11, p<0.001) versus chance.
