Story summary

Apple researchers developed PAirwise Relative Shift (PARS), a self-supervised AI model to analyze brain electrical activity without annotated data.
It predicts temporal relationships between EEG segments and improves sleep staging and seizure detection.
The study notes that existing models rely heavily on human-annotated data, which can be costly.
Apple is exploring ear-EEG integration with AirPods to monitor brain activity, but ear-EEG devices may struggle to maintain contact, reducing accuracy.
