Signatures of life course socioeconomic conditions in brain anatomy

Maria del Carmen Sandi Perez, Bogdan Draganski

Socioeconomic status (SES) plays a significant role in health and disease. At the same time, early-life conditions affect neural function and structure, suggesting the brain may be a conduit for the biological embedding of SES. Here, we investigate the bra ...

Effects of eight neuropsychiatric copy number variants on human brain structure

Claudia Modenato, Kuldeep Kumar, Bogdan Draganski, Lester Melie Garcia, Borja Rodriguez Herreros

Many copy number variants (CNVs) confer risk for the same range of neurodevelopmental symptoms and psychiatric conditions including autism and schizophrenia. Yet, to date neuroimaging studies have typically been carried out one mutation at a time, showing ...

The role of population receptive field size and recurrent processing in learning to “de-crowd”

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Ayberk Ozkirli

In crowding, the perception of a target is impeded by surrounding clutter. While traditional models are feedforward and local, there is increasing behavioral and neural evidence for a critical role of recurrent processing across the visual hierarchy in cro ...

Unraveling brain interactions in vision: the example of crowding

Michael Herzog, Vitaly Chicherov, Maya Anna Jastrzebowska, Bogdan Draganski

Crowding, the impairment of target discrimination in clutter, is the standard situation in vision. Traditionally, crowding is explained with (feedforward) models, in which only neighboring elements interact, leading to a “bottleneck” at the earliest stages ...

Population receptive field size in (un)crowding: to isolate or to combine?

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Ayberk Ozkirli

Traditional models posit that visual processing is local and feedforward. In this vein, crowding is explained to be the result of pooling of target and flanker features in early visual areas. Specifically, it has been suggested that when the target and fla ...

Remodeling of brain morphology in temporal lobe epilepsy

Bogdan Draganski, Lester Melie Garcia

Background Mesial temporal lobe epilepsy (TLE) is one of the most widespread neurological network disorders. Computational anatomy MRI studies demonstrate a robust pattern of cortical volume loss. Most statistical analyses provide information about localiz ...

Dopaminergic modulation of motor network compensatory mechanisms in Parkinson's disease

Michael Herzog, Maya Anna Jastrzebowska, Renaud Marquis, Bogdan Draganski

The dopaminergic system has a unique gating function in the initiation and execution of movements. When the interhemispheric imbalance of dopamine inherent to the healthy brain is disrupted, as in Parkinson's disease (PD), compensatory mechanisms act to st ...

Dopaminergic modulation of cortical motor network lateralization

Michael Herzog, Maya Anna Jastrzebowska, Renaud Marquis, Bogdan Draganski, Lester Melie Garcia

Introduction Unilateral movements are primarily processed in contralateral cortical and subcortical areas and additionally in ipsilateral cerebellum, leading to an asymmetric pattern of neural activation. Decrease of lateralization is characteristic of agi ...

Controlling motion artefact levels in MR images by suspending data acquisition during periods of head motion

Bogdan Draganski

Purpose: Head movements are a major source of MRI artefacts. Prospective motion correction techniques significantly improve data quality, but strong motion artefacts may remain in the data. We introduce a framework to suspend data acquisition during period ...

Sustained enhancements in inhibitory control depend primarily on the reinforcement of fronto-basal anatomical connectivity

Michaël Mouthon, Wietske Van der Zwaag, Bogdan Draganski

What are the neurophysiological determinants of sustained supra-normal inhibitory control performance? We addressed this question by coupling multimodal neuroimaging and behavioral investigations of experts in fencing who underwent more than 20,000 h of in ...

The Number of Genomic Copies at the 16p11.2 Locus Modulates Language, Verbal Memory, and Inhibition

Nouchine Hadjikhani, Loyse Hippolyte, Bogdan Draganski, Borja Rodriguez Herreros

BACKGROUND: Deletions and duplications of the 16p11.2 BP4-BP5 locus are prevalent copy number variations (CNVs), highly associated with autism spectrum disorder and schizophrenia. Beyond language and global cognition, neuropsychological assessments of thes ...

Differential patterns of functional and structural plasticity within and between inferior frontal gyri support training-induced improvements in inhibitory control proficiency

Michaël Mouthon, Wietske Van der Zwaag, Bogdan Draganski

Ample evidence indicates that inhibitory control (IC), a key executive component referring to the ability to suppress cognitive or motor processes, relies on a right-lateralized fronto-basal brain network. However, whether and how IC can be improved with t ...

Automatic target validation based on neuroscientific literature mining for tractography

Jean-Cédric Chappelier, Sean Lewis Hill, Renaud Luc Richardet, David Slater, Xavier Vasques, Bogdan Draganski, Jocelyne Bloch

Target identification for tractography studies requires solid anatomical knowledge validated by an extensive literature review across species for each seed structure to be studied. Manual literature review to identify targets for a given seed region is ted ...
