Revolutionizing Pediatric Brain Imaging
Quantum technologies, particularly in the form of magnetoencephalography (MEG), are transforming how brain function is studied in children. This technique provides exceptional temporal and spatial resolution for assessing brain activity, focusing specifically on disorders that affect brain function, such as autism. The integration of optically pumped magnetometers within wearable helmets allows for more effective brain scans, accommodating the natural movements of young children and providing a more accurate representation of brain signals. This advancement enables researchers to monitor early brain function and may facilitate earlier diagnoses and interventions for conditions like autism.
