“…Perceptive-motor information has been traditionally studied through the child's capacity to use a body-based frame of reference. Along these lines, path integration characteristics throughout infant growth have not been fully studied, and a lack of tools has been identified in this field [ 67 , 79 , 80 ]. In this review, only four articles specifically focused on the assessment of path integration in TD children [ 29 , 66 , 67 , 68 ].…”

“…In addition, the largest differences between groups were identified for the precuneus (Figures 6-8), which is one of the main hubs of the brain network and part of the DMN. Alterations in the connectivity of this network have been associated with ADHD (Castellanos & Aoki, 2016; Elton et al, 2014; Gracia-Tabuenca et al, 2020), visuospatial abilities (Fernandez-Baizan et al, 2021; Woodward et al, 2021) episodic memory (Schommartz et al, n.d.; Stedall et al, 2023), affective disorders (Guilherme Monte Cassiano et al, 2016) and social cognition (Pereira et al, 2017; You et al, 2019). Our results suggest a link between these brain functional alterations and the vulnerability to develop such behavioral disorders.…”

Premature infants, born before 37 weeks of gestation can have consequences on neurodevelopment and cognition, even when no anatomical lesions are evident. Resting-state functional neuroimaging of naturally sleeping babies has shown altered connectivity patterns, but there is limited evidence on the developmental trajectories of the functional organization in preterm neonates. By using a large dataset (n=597) from the developing Human Connectome Project, we explored the differences in graph theory properties between at-term and preterm neonates at term-equivalent age, considering the age subgroups proposed by the World Health Organization for premature birth. Leveraging the longitudinal follow-up for some preterm participants, we characterized the developmental trajectories for preterm and at-term neonates. We found significant differences between groups for connectivity strength, clustering coefficient, characteristic path length and global efficiency. Specifically, at term-equivalent ages, higher connectivity, clustering coefficient and efficiency are identified for neonates born at higher postmenstrual ages. Similarly, the characteristic path length showed the inverse pattern. These results were consistent for a variety of connectivity thresholds and both at the global (whole brain) and local level (brain regions). The brain regions with the greatest differences between groups include primary sensory and motor regions and the precuneus which may relate with the risk factors for sensorimotor and behavioral deficits associated with premature birth.Our results also show non-linear developmental trajectories for premature neonates, but decreased integration and segregation even at term-equivalent age. Overall, our results confirm altered functional connectivity, integration and segregation properties of the premature brain despite showing rapid maturation after birth.

“…The underlying reasons for this cannot be extracted from our study. However, the relationship between preterm birth and visuospatial abilities has been described (41,43,45,(66)(67)(68) and could influence execution, taking into account that these abilities are essential to develop whole-body movements and move into the space (26,27).…”

“…Although Bartonek and colleagues (5) did not determine what aspect could contribute more to spatial cognition deficits, they agreed that prematurity could influence, as stated also in other studies (41-43). Fernandez-Baizan et al evidenced how 22 months old preterm infants performed worse than their peers when remembering a location and updating learned information (43). Also, 5-6 years old children born preterm with low birth weight have difficulty orienting themselves using an allocentric strategy (42).…”

IntroductionTopographical memory is crucial for navigation and environmental representation. The Walking Corsi Test (WalCT) has been used to evaluate topographical memory in children from 4 years upward. The present study aims to determine whether adapted versions of the WalCT- by simplifying instructions and increasing motivation- can be adopted to test topographical memory in 2- and 3-year-old toddlers born at term and preterm. Assessing this skill in such young children is important in light of recent studies that have shown how spatial cognition underlies the development of skills in other cognitive domains as well. Methods: For this purpose, 47 toddlers (27.39 ± 4.34 months, 38.3% females), 20 born at term and 27 preterm, performed two aimed-designed versions of WalCT.ResultsThe results showed better performance of the term groups with increasing age and for both versions. On the other hand, performance was better in 2-year-old term toddlers vs. preterm. When rising motivation, 2-year-old preterm toddlers improve their performance but differences between both groups were still significant. The preterm group showed lower performance related to lower levels of attention.DiscussionThis study provides preliminary data on the suitability of the adapted versions of WalCT in early ages and prematurity conditions.
