New Working Memory Paradigm for Neuroimaging Testing of Visual and Verbal Modality under Different Attentional Involvement
Psychology. Journal of the Higher School of Economics. 2024. No. 3. P. 456–471.
Working memory (WM) is a cognitive function essential for short-term maintenance of information in a highly accessible state to support goal-directed behavior. The classical behavioral model of WM includes a visuospatial sketchpad, a phonological loop and the central executive. Neuroimaging studies selectively targeted the activity associated with maintenance and processing of modality specific information. However, an experimental design is still missing that would enable the assessment of all components of WM drawing a holistic neuroimaging model. In this study, we propose a modified paradigm based on the classical retro-cue task, which allows disentangling the activity of all WM components, and in particular of the central executive. This paradigm consists of five conditions: passive perception, simple verbal storage, simple visual storage, alphabetical reordering (complex verbal) and mental rotation (complex visual). Testing on a cohort of 35 healthy adults, we obtained a similar workload for simple storage conditions with a low engagement of the central executive. A different workload was verified between the simple and complex conditions in both verbal and visual modalities. This experimental design provides the framework to assess the neural activity associated with the central executive components in different modalities and to address the question of a unitary or modality-specific central executive nature. Therefore, the paradigm is suitable for utilization in neuroimaging to potentially advance our comprehension of the WM organization.

Embodied and embedded cognition (EEC) theory proposes that language and cognitive development emerge from bodily interactions with the environment, yet empirical tests of this claim in clinical developmental populations remain rare. This mini-review synthesizes behavioral, electrophysiological, and structural neuroimaging evidence from children with serious early motor disorders—obstetric brachial plexus palsy and arthrogryposis multiplex congenita—which restrict ...

Single amino acid substitutions in the ATP-binding domain of ACVRL1, a key receptor in the bone morphogenetic protein (BMP) signaling pathway, are frequently classified as variants of uncertain significance (VUS), complicating molecular diagnosis for pulmonary arterial hypertension (PAH) and Hereditary Hemorrhagic Telangiectasia (HHT). Since aberrant ATP binding disrupts downstream SMAD1/5/8 phosphorylation, we employed molecular dynamics ...

Background Cardiac fibrosis represents a significant health burden, with endothelial dysfunction and damaged
perivascular microenvironment increasingly recognized as key contributors to fibrotic remodeling. The urokinase
plasminogen activator receptor (uPAR), a critical component of the urokinase system, plays a pivotal role in vascular
remodeling and fibrosis. While prior evidence indicates that uPAR deficiency leads to microvascular dysfunction and
perivascular fibrosis, ...

Anxiety is a multidimensional construct that influences cognitive performance in complex ways, yet its factor structure and domain-specific effects remain unclear. This study examined (1) the psychometric structure of general and specific anxiety measures, (2) their associations with cognitive performance across different domains, and (3) the predictive power of machine learning models in classifying cognitive ...

In psychology, people's assessment of conditional statements "if--then", agreement and disagreement with them is actively studied. This assessment of people who are not specialists in the field of logic often differs greatly from its requirements, especially if the reality observed by a person to one degree or another contradicts a formally correct logical conclusion. In ...

Background. Individual activation maps based on brain functional magnetic resonance imaging (fMRI) data cannot yet be applied to refine a patient's diagnosis and prognosis. However, tracking activation dynamics in the same patient during the course of treatment or rehabilitation can be useful for assessing their efficacy.
