Fig. 2: Box plots of amplitude for within- and inter-area connectivity (z-scores) and their frequency distributions in different GA groups.
From: Differential age-dependent development of inter-area brain connectivity in term and preterm neonates

Preterm infants born before 30 weeks of GA = Low GA preterm; preterm infants born after 30 weeks of GA = High GA preterm; term infants = Term. Connectivity within frontal or temporal areas = Within; inter-area connectivity = Inter. Big dots in the center indicate averaged values.
