“…22 The brain circuits that underlie spatial working memory include the prefrontal cortex, anterior cingulate cortex, basal ganglia, thalamus, and cerebellum. 23 PE-F1 presented with higher parallel diffusion values in the cingulate gyrus (On-line Table), which corresponds to additional support for differences in the PE-F1 limbic area. DTI identification of higher FA values and a higher volume of white matter tracts on the caudate nucleus plus higher parallel diffusion on the cingulate gyrus predict an impact on spatial working memory in PE-F1 compared with control children.…”

BACKGROUND AND PURPOSE: Individuals born from pregnancies complicated by preeclampsia have an elevated risk for cognitive impairment. Deviations in maternal plasma angiokines occur for prolonged intervals before clinical signs of preeclampsia. We hypothesized that fetal brain vascular and nervous tissue development become deviated during maternal progression toward preeclampsia and that such deviations would be detectable by MR imaging.

“…One possibility would be to use eye-tracking measures to assess nonverbal inhibition in those with DCD. For example, the antisaccade task measures the ability to inhibit a reflexive eye movement towards a stimulus and look towards an alternative location (Luna, Velanova, & Geier, 2008).…”

AbstractThe current study assessed a comprehensive range of executive functions (EFs) in children with poor motor skills, comparing profiles of children with a diagnosis of developmental coordination disorder (DCD) and those identified with motor difficulties (MD). Children in both groups performed more poorly than typically-developing controls on (Geuze, 2005). The DLPFC is also closely linked to the cerebellum, a central structure in motor control, suggesting that motor impairments could have concomitant effects on cognitive functioning (Diamond, 2000). This relationship between motor and cognitive functioning is the focus of the present study.One area of cognitive functioning that may be affected in DCD, with particular implications for academic achievement, is that of 'executive functioning' (EF; Best, Miller, & Naglieri, 2011;St Clair-Thompson & Gathercole, 2006). This term covers a range of highlevel abilities, including planning, switching between tasks, inhibiting responses and storing information in memory while processing another task (Henry & Bettenay, 2010;Hill, 2004 & Howerter, 2000), the present study also assesses two further aspects of EF, planning and fluency, which have traditionally been studied in research with frontal lobe patients and those with other neurodevelopmental disorders (Pennington & Ozonoff, 1996).The current paper provides a detailed picture of the strengths and weaknesses of EF in children with DCD.Previous research investigating EF in DCD has reported mixed results. In measures of response inhibition, which require participants to either respond or inhibit their responses depending on the stimulus presented, children with a diagnosis of DCD make a similar number of errors to TD controls (e.g., Pratt, Leonard, Adeyinka, & Hill, 2014;Querne et al., 2008). However, when comparing button presses that were either congruent or incongruent with a visually-presented target, Mandich, Buckolz, and Polatajko (2002) reported that differences in errors between these two conditions were greater for those with DCD compared to TD controls. In tests of switching (e.g., "press button 'a' when you see stimulus Several methodological and interpretational difficulties arising from previous research into EF in DCD were addressed in the current study. One key issue is that many EF tasks require a motor response (such as pressing a button) or complex visuospatial processing, both of which may cause individuals with DCD to perform poorly due to impairments in these (...

“…Anatomical changes in the prefrontal cortex continue during adolescence, involving gray and white matter volumes and myelination of axon fibers within the prefrontal cortex and between the prefrontal cortex and other areas (8)(9)(10)(11)(12)(13)(14)(15). Changes in prefrontal activation, including increases (12,(16)(17)(18)(19)(20) and decreases (21,22), have been documented in imaging studies for tasks that require inhibition of prepotent behavioral responses and filtering of distractors.…”

Executive functions including behavioral response inhibition mature after puberty, in tandem with structural changes in the prefrontal cortex. Little is known about how activity of prefrontal neurons relates to this profound cognitive development. To examine this, we tracked neuronal responses of the prefrontal cortex in monkeys as they transitioned from puberty into adulthood and compared activity at different developmental stages. Performance of the antisaccade task greatly improved in this period. Among neural mechanisms that could facilitate it, reduction of stimulus-driven activity, increased saccadic activity, or enhanced representation of the opposing goal location, only the latter was evident in adulthood. Greatly accentuated in adults, this neural correlate of vector inversion may be a prerequisite to the formation of a motor plan to look away from the stimulus. Our results suggest that the prefrontal mechanisms that underlie mature performance on the antisaccade task are more strongly associated with forming an alternative plan of action than with suppressing the neural impact of the prepotent stimulus.prefrontal | antisaccade | monkey | neurophysiology | adolescence B ehavioral response inhibition, and cognitive task performance more generally, improves substantially between the time of puberty and adulthood (1-4). Risky decision-making peaks in adolescence, the time period between puberty and adulthood that is most closely linked to delinquent behavior in humans (5-7). Performance in tasks that assay response inhibition, such as the antisaccade task, improves into adulthood, reflecting the progressive development of behavioral control (3). This period of cognitive enhancement parallels the maturation of the prefrontal cortex (8-11). Anatomical changes in the prefrontal cortex continue during adolescence, involving gray and white matter volumes and myelination of axon fibers within the prefrontal cortex and between the prefrontal cortex and other areas (8-15). Changes in prefrontal activation, including increases (12,(16)(17)(18)(19)(20) and decreases (21, 22), have been documented in imaging studies for tasks that require inhibition of prepotent behavioral responses and filtering of distractors.Much less is known about how the physiological properties of prefrontal neurons develop after puberty. Similar to the human pattern of development, the monkey prefrontal cortex undergoes anatomical maturation in adolescence and early adulthood (23,24). Male monkeys enter puberty at ∼3.5 y of age and reach full sexual maturity at 5 y, approximately equivalent to the human ages of 11 y and 16 y, respectively (25,26). By some accounts, biochemical and anatomical changes characteristic of adolescence in humans occur at an earlier, prepubertal age in the monkey prefrontal cortex (27, 28), so it is not known if cognitive maturation or neurophysiological changes occur in monkeys after puberty. The contribution of prefrontal cortex to antisaccade performance has also been a matter of debate, with contrasting views fav...
