Functional investigation of the networks and white matter substrates associated with the processing of mathematical operations

Малютина С. А., Погосбекян Э. Л., Баталов А. И. и др., В кн.: Когнитивная наука в Москве: новые исследования. Материалы конференции 15 июня 2017 г.: Буки Веди, 2017. С. 231–236.

Представляется, что возрастные и индивидуальные различия присутствуют не только в таких высших психических функциях, как восприятие, память, внимание, мышление, но и в языковой обработке (речи), где они пока изучены гораздо меньше. Например, в отношении синтаксической обработки до сих пор нет окончательного ответа, нарушается ли с возрастом только её скорость, либо также правильность. Целью данной работы ...

Boosting connectome classification via combination of geometric and topological normalizations

Petrov D., Dodonova Y., Жуков Л. Е. и др., , in: PRNI 2016. The 6th International Workshop on Pattern Recognition in Neuroimaging. Trento, Italy, June 22nd – 24th, 2016.: NY: IEEE, 2016. P. 1–4.

The structural connectome classification is a challenging task due to a small sample size and high dimensionality of feature space. In this paper, we propose a new data prepossessing method that combines geometric and topological connectome normalization and significantly improves classification results. We validate this approach by performing classification between autism spectrum disorder and normal ...

Correction Strategy for Diffusion-Weighted Images Corrupted with Motion: Application to the DTI Evaluation of Infants White Matter

Dubois J., Куликова С. П., Hertz-Pannier L. и др., Magnetic Resonance Imaging 2014 Vol. 32 No. 8 P. 981–992

Objective Diffusion imaging techniques such as DTI and HARDI are difficult to implement in infants because of their sensitivity to subject motion. A short acquisition time is generally preferred, at the expense of spatial resolution and signal-to-noise ratio. Before estimating the local diffusion model, most pre-processing techniques only register diffusion-weighted volumes, without correcting for intra-slice artifacts ...

The Early Development of Brain White Matter: A Review of Imaging Studies in Fetuses, Newborns and Infants.

Dubois J., Dehaene-Lambertz G., Куликова С. П. и др., Neuroscience 2015 Vol. 276 P. 48–71

Studying how the healthy human brain develops is important to understand early pathological mechanisms and to assess the influence of fetal or perinatal events on later life. Brain development relies on complex and intermingled mechanisms especially during gestation and first post-natal months, with intense interactions between genetic, epigenetic and environmental factors. Although the baby's brain ...

Exploring the early organization and maturation of linguistic pathways in the human infant brain

Dubois J., Poupon C., Thirion B. и др., Cerebral Cortex 2015 Vol. 26 No. 5 P. 2283–2298

Linguistic processing is based on a close collaboration between temporal and frontal regions connected by two pathways: the “dorsal” and “ventral pathways” (assumed to support phonological and semantic processing, respectively, in adults). We investigated here the development of these pathways at the onset of language acquisition, during the first post-natal weeks, using cross-sectional diffusion imaging ...

Multi-parametric evaluation of the white matter maturation

Куликова С. П., Hertz-Pannier L., Dehaene-Lambertz G. и др., Brain Structure and Function 2015 Vol. 220 No. 6 P. 3657–3672

In vivo evaluation of the brain white matter maturation is still a challenging task with no existing gold standards. In this article we propose an original approach to evaluate the early maturation of the white matter bundles, which is based on comparison of infant and adult groups using the Mahalanobis distance computed from four complementary MRI ...
