Due to the absence of myelin at birth, tissues
properties of the neonatal brain are strongly different
of the adults brain. Realistic newborn head model is
required to compute accurate EEG source imaging. We
built segmented templates of preterm and full-term
newborns brain using segmentation of individual
structural MRI. Electrical conductivity can be assigned
to each type of tissue to build a realistic model for
EEG source localization. These templates and their
corresponding tissue probability maps could also be used
for tissue masking or as prior for subsequent analyses.
