“…In TD children, the ability to disengage attention increases over developmental time (e.g. Kulke, Atkinson, & Braddick, 2017) and then is likely to plateau due to its relationship with the development of the splenium of the corpus callosum (Elison et al, 2013), which has a decreasing rate of expansion (Ansado et al, 2015). It is therefore possible that the ability to disengage attention is slow (relative to TD) only during infancy and toddlerhood in DS.…”

The ability to actively select and attend to relevant aspects of the ever-changing environment, by shifting one's focus of visual attention, is crucial for learning and development (Stevens & Bavelier, 2012). For example, Slaughter and McConnell (2003) found that an infant's ability to follow gaze is related to their language ability. It is therefore possible that infants use eye gaze to infer what object or event is being referred to and labelled by their caregiver; certainly, infants are more likely to learn an object's label if the object being labelled dominates their visual field (Pereira, Smith, & Yu, 2014). Also, the ability to match auditory and visual information positively correlates with language ability, which suggests that visual processing bootstraps word learning (Bahrick, Todd, & Soska, 2018). Consequently, any irregularity in shifting attention may constrain how one interacts with, and thus learns from, the environment, with deleterious effects. Irregularities in shifting attention have been observed in children with neurodevelopmental

“…As in the present study, Giedd et al [22] showed no statistically significant effect of sex on genu, splenium, or total corpus callosal areas at any age based on the linear regression analyses (see below). Recently, a comprehensive but age-limited MRI investigation has been published that incorporated 3 rather than 2 dimensions into the measurement of corpus callosal size in 370 children and adolescents aged 4-18 years [6] . Volume determinations mimicked area values for the genu and splenium, of which the structures exhibited greater rates of growth of those individuals younger than 7 years of age, as in the present study and those of Giedd et al [22,23] .…”

“…Despite their very thorough investigation, studies continue to be published with an emphasis on sex differences in corpus callosal size and shape, again with variable results [3,19,[30][31][32] . These disparate results, in part, might be related to variations in the partitioning of the corpus callosum into its component parts by the different investigators [6] . No or minimal sex differences have also been observed for the corpus callosal microstructure determined by diffusion tensor imaging on MRI.…”

Development of the Corpus Callosum: An MRI Study

The size and shape of the corpus callosum and its major components (genu, body, and splenium) were measured by magnetic resonance imaging (MRI) in 118 normocephalic individuals aged from 1 postnatal week to 18.7 years. Genu, body, splenial, and total corpus callosal areas increased by 40-100% during the first year of life (p < 0.05). The genu expanded to a greater extent than the splenium during the first 6 years, while the splenium expanded to a greater extent between 7 and 18 years. The age-related difference in the maximal expansion of these structures indicated an anterior to posterior wave of corpus callosal enlargement during maturation, probably the consequence of differential axonal myelination. No sex differences existed during these two developmental phases for the genu, splenial, or total corpus callosal areas with or without scaling to the cerebral hemispheric volume. During infancy (0-24 months), however, the mean female splenial ratio (length/height) of 0.79 was greater than the male ratio of 0.65 (p = 0.024). The cerebral hemispheric length/height ratio was also greater in females, indicating that during infancy the female brain (and its component the corpus callosal splenium) is relatively longer than the male brain. This sex difference was confined to the splenium and disappeared with increasing age.

“…These studies focused on linear measurement and cross-sectional area measurements in mid-sagittal MRI (Garel et al, 2011;Giedd et al, 1996Giedd et al, , 1999Habib et al, 1991;Keshavan et al, 2002;Suganthy et al, 2003;Tanaka-Arakawa et al, 2015;Vannucci et al, 2017). To our knowledge, only Ansado et al investigated the three-dimensional (3D) volumetric development of CC in the pediatric age group (Ansado et al, 2015). Although their study population was large, they did not examine the development of CC during the first 4 years of life, when brain development is critical.…”

Three dimensional development and asymmetry of the corpus callosum in the 0–18 age group: A retrospective magnetic resonance imaging study

Most of the corpus callosum (CC) developmental studies are concerned with its twodimensional structure. Linear and area measurements do not directly assess the CC size but estimate the overall structure from the cross-sectional image. This study investigated age-and sex-related changes in volumetric development and asymmetry of CC from birth to 18. For this retrospective study, we selected 696 patients (329 [47.27%] females) with both 3D-T1-weighted sequence and normal radiological anatomy from patients 0-18 years of age who had brain magnetic resonance imaging (MRI) between 2012 and 2020. The genu, body, splenium, and total volume of CC were calculated using MRICloud. The measurement results of 23 age groups were analyzed with SPSS (ver.28). Total CC volume was 18740.76 ± 4314.06 mm 3 between 0 and 18 years of age, and its ratio to total brain volume (TBV) was 1.70% ± 0.23%. We observed that the total CC volume has six developmental periods 0 years, 1, 2-4, 5-9, 10-16, and 17-18 years. Genu and body grew in five develop-
