Study Summary

MagnetoEncephaloGraphy (MEG) is a method of recording brain activity with high temporal resolution and good spatial resolution, compared to current recording techniques such as ElectroEncephaloGraphy (EEG). The main limitation of MEG is its cost due to the sensors used, the Super Quantum Interference Devices (SQUID). These require a complex infrastructure from an instrumentation point of view to operate, requiring liquid helium, most often at a loss, at increasing cost. Optical Pumping Magnetometers (OPM) type sensors represent a promising alternative to SQUIDs sensors, especially since they do not require helium cooling.

The purpose of this project is to Identify biomarkers in Magnetoencephalography of normal brain development in healthy adults, premature and term newborns from "a priori" obtained by the classical technique of High Resolution EEG performed.

Eligibility Criteria

Inclusion

  • No pathology, no treatment

  • For children born prematurely

  • Child between 28 and 36 weeks gestational age on the day of registration

  • No pathology, no treatment apart from routine care related to prematurity

Exclusion

Exclusion Criteria:
