Non-Contact Brain Activity Detection Technologies

The provided sources explore various non-invasive techniques for detecting and imaging brain activity, moving beyond traditional methods like EEG. Several articles highlight the potential of photoacoustic computed tomography and functional ultrasound imaging for observing human brain function, even transcranially. Other research investigates electromagnetic brain scanners, radar data for brain atrophy monitoring, and infrared radiation (thermoencephaloscopy) as means to assess brain activity and changes. Additionally, the texts mention the use of optically pumped magnetometers for next-generation magnetoencephalography and infrared cameras for non-contact measurement of brain activity through pupillary rhythms, all demonstrating a significant push towards less intrusive neuroimaging methods.
