CDKL5 sculpts functional callosal connectivity to promote cognitive flexibility

Functional and structural connectivity alterations in short- and long-range projections have been reported across neurodevelopmental disorders (NDD). Interhemispheric callosal projection neurons (CPN) represent one of the major long-range projections in th ...

Theta oscillations and minor hallucinations in Parkinson’s disease reveal decrease in frontal lobe functions and later cognitive decline

Olaf Blanke, Fosco Bernasconi

Cognitive decline and hallucinations are common and debilitating non-motor symptoms, usually occurring during later phases of Parkinson’s disease (PD). Minor hallucinations (MH) appear early in the disease course and have been suggested to predict cognitiv ...

On the Spatial Distribution of Temporal Complexity in Resting State and Task Functional MRI

Dimitri Nestor Alice Van De Ville, Maria Giulia Preti, Enrico Amico, Raphaël Pierre Liégeois, Amir Hossein Omidvarnia

Measuring the temporal complexity of functional MRI (fMRI) time series is one approach to assess how brain activity changes over time. In fact, hemodynamic response of the brain is known to exhibit critical behaviour at the edge between order and disorder. ...

Impaired cognitive flexibility and heightened urgency are associated with increased alcohol consumption in rodent models of excessive drinking

Emanuela De Falco

Alcohol use disorder (AUD) is characterized by impairments in decision-making that can exist as stable traits or transient states. Cognitive inflexibility reflects an inability to update information that guides decision-making and is thought to contribute ...

White matter hyperintensities at critical crossroads for executive function and verbal abilities in small vessel disease

Nathalie Heidi Meyer

The presence of white matter lesions in patients with cerebral small vessel disease (SVD) is among the main causes of cognitive decline. We investigated the relation between white matter hyperintensity (WMH) locations and executive and language abilities i ...

How ageing shapes body and space representations: A comparison study between healthy young and older adults

Olaf Blanke, Andrea Serino, Michela Bassolino, Matteo Franza, Giuliana Sorrentino, Charlène Zuber

To efficiently interact with the external world, the brain needs to represent the size of the involved body parts - body representations (BR) - and the space around the body in which the interactions with the environment take place - peripersonal space rep ...

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

Patric Hagmann, Stephanie Clarke

A brief session of rightward prismatic adaptation (R-PA) has been shown to alleviate neglect symptoms in patients with right hemispheric damage, very likely by switching hemispheric dominance of the ventral attentional network (VAN) from the right to the l ...

Electrophysiological correlates of visual backward masking in patients with major depressive disorder

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Depression and schizophrenia are two psychiatric diseases with high co-morbidity. For this reason, it is important to find sensitive endophenotypes, which may disentangle the two disorders. The Shine-Through paradigm, a visual backward masking task, is a p ...

Alpha/beta power decreases track the fidelity of stimulus-specific information

João Pedro Forjaco Jorge

Massed synchronised neuronal firing is detrimental to information processing. When networks of task-irrelevant neurons fire in unison, they mask the signal generated by task-critical neurons. On a macroscopic level, such synchronisation can contribute to a ...

The effect of frontoparietal paired associative stimulation on decision-making and working memory

Traian Popa

Previous single-site neurostimulation experiments have unsuccessfully attempted to shift decision-making away from habitual control, a fast, inflexible cognitive strategy, towards goal-directed control, a flexible, though computationally expensive strategy ...

Is lack of attention necessary for task-irrelevant perceptual learning?

Michael Herzog, Lukasz Grzeczkowski, Jessica Galliussi

Perceptual learning can occur for a feature irrelevant to the training task, when it is sub-threshold and outside of the focus of attention (task-irrelevant perceptual learning, TIPL); however, TIPL does not occur when the task-irrelevant feature is supra- ...

Causal role of the inferolateral prefrontal cortex in balancing goal-directed and habitual control of behavior

Friedhelm Christoph Hummel

Successful adaptation to complex environments depends on the balance of at least two systems: a flexible but slow goal-directed system encoding action-outcome associations and an efficient but rigid habitual system linking responses to preceding stimuli. R ...

Comparisons of verbal fluency brain correlates between adults and adolescents suffering from schizophrenia spectrum disorders: A pilot study

Pierre Magistretti, Pierre Marquet

Background and Objectives: Prefrontal cortex (PFC) dysfunctions leading to cognitive deficits refer to a core feature of schizophrenia spectrum disorders (SSD). This exploratory study compares the effect of SSD on two stages of maturation of PFC. Methods: ...

Gender differences in visual perception

Michael Herzog, Christine Mohr, Maya Roinishvili, Albulena Jashari-Shaqiri

Gender differences are well established in cognition and somato-sensation, but there are almost no studies on gender differences in visual perception. One reason is that sample size is often small because effect sizes are large. Small samples are not well ...

Impaired cognitive functioning in first-episode patients

Michael Herzog, Maya Roinishvili

The first psychotic episode is an important period for prevention of cognitive and social deterioration in schizophrenia. Cognitive deficits are of particular interest since they are evident even before a proper diagnosis can be made. Interestingly, there ...

Cognitive markers as potential endophenotypes for schizophrenia

Michael Herzog, Maya Roinishvili

Schizophrenia is a heterogeneous disease strongly influenced by genetic predisposition. A large variety of candidate genes has been identified of which each gene, however, explains only a small proportion of the genetic risk. For this reason, stable marker ...

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

Wietske Van der Zwaag, Bogdan Draganski, Michaël Mouthon

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 ...

Apathy and noradrenaline: silent partners to mild cognitive impairment in Parkinson's disease?

Leyla Loued-Khenissi, Kerstin Preuschoff

Purpose of review Mild cognitive impairment (MCI) is a comorbid factor in Parkinson's disease. The aim of this review is to examine the recent neuroimaging findings in the search for Parkinson's disease MCI (PD-MCI) biomarkers to gain insight on whether MC ...

Social reward improves the voluntary control over localized brain activity in fMRI-based neurofeedback training

Yury Koush

Neurofeedback (NF) based on real-time functional magnetic resonance imaging (rt-fMRI) allows voluntary regulation of the activity in a selected brain region. For the training of this regulation, a well-designed feedback system is required. Social reward ma ...

Deconstructing the Default: Cortical subdivision of the Default Mode/Intrinsic System During Self-Related Processing

Roy Salomon

Recent brain imaging research has highlighted a new global system of areas termed the Default Mode network (DM), which appears to specialize in intrinsically oriented functions. However, it is still unresolved to what extent this system contains functional ...
