Pediatric Neurology

Medical procedures may be traumatic for children and parents alike. From many years of experience with dEEG in child development research laboratories, GeoMedica's scientists and support engineers have learned from our child research customers how to make the dEEG examination painless and enjoyable for both children and their parents.

Kid Friendly

The Geodesic Sensor Net is a gentle, non-invasive, and painless tool for recording dense array EEG. Most infants forget they are wearing the Net soon after it is applied.

Our dense array EEG customers apply the Net with smooth confident actions, distract children with engaging toys, and thereby make good use of the child's attention and affect to gain high quality dEEG recordings.

Whether in hospitals or outpatient clinics, careful design of the technology, procedures, and environment allows acquisition of high quality dEEG data even with difficult children without restraints or sedation. The result is a major improvement in the response of children, and their parents, to the EEG evaluation.

Spatial Sampling of Pediatric EEG

Because the immature skull is highly conductive to the brain's electrical fields, it does not distort (spread) the fields as much as in adults. The result is a higher spatial frequency (more detailed map) of the brain's electricity appearing at the scalp. The result is that greater sampling density is required for children and infants than for adults (Grieve et al., 2004). GeoMedica has now adapted Geodesic Sensor Net 128-channel array for neonates, and is working on new designs to fit neonates (and even preemies) with 256 and higher channel counts. Research now underway will bring conductivity scanning methods and improved analysis of brain wave propogation for every child.
