Background: structural and neurochemical abnormalities in temporal lobe and temporoparietal junction (T-TPJ) are seen not only in Alzheimer’s disease (AD) but also in amnestic mild cognitive impairment (aMCI). At the same time, studies of conversion to dementia focused on functional characteristics of these regions are lacking.
The aim was to search for patterns of functional connectivity (FC) within T-TPJ that differentiate patients with aMCI with future conversion to AD from stable aMCI patients and healthy controls.
Patients, Comparison Group and Methods: patients with aMCI who further converted to dementia due to AD (converters, n = 15), patients with stable aMCI (n = 12), and healthy individuals without cognitive deficits (n = 29) underwent resting-state functional magnetic resonance imaging. FC between cortical T-TPJ structures was compared between groups separately for each hemisphere (one-way ANCOVA and post hoc between-group comparisons).
Results: an increased FC between posterior parts of left middle and inferior temporal gyri was observed in converters compared to other groups. There was an inverse correlation between this FC and delayed recall of words (MoCA scale) in the entire sample, however, this correlation did not reach the level of statistical significance (p = 0.055).
Conclusions: the posterior parts of left middle and inferior temporal gyri are involved in auditory verbal memory and storing of visual images associated with a word, respectively. Therefore, а pattern of increased FC observed in future converters to AD may be a consequence of pathological processes that have already started and/or compensatory mechanisms.

The Reading the Mind in the Eyes Test (RMET) is a widely used tool for assessing affective mentalization in both clinical and research contexts. Although translated into many languages, no validated Russian-language version has been available. Furthermore, the limited number of stimuli in the original RMET constrains its applicability in neuroimaging studies. This study presents ...

Acute ischemic stroke (AIS) analysis from two-dimensional (2D) clinical imaging is hindered by uncontrolled slice tilt and geometric inconsistencies that violate the assumptions of pose-agnostic deep learning (DL) models. This paper proposes a unified geometry-aware, frequency-domain framework for tilted slice localization and ischemic stroke segmentation that explicitly decouples pose estimation from lesion analysis. The method ...

Background/Objectives: Synolitic graphs (SGs) were developed for task-based fMRI, where
edge weights encode the discriminative power of pairwise regional features; whether similar
information can be recovered from resting-state data was untested. We benchmarked
SGs for autism spectrum disorder (ASD) classification using the multisite ABIDE-I dataset
(871 subjects: 403 subjects with ASD, 468 typical controls; 17 sites; CC200 atlas). Methods:

Electronic health records (EHRs) contain vast volumes of clinical information that encode complex relationships between diseases. Traditional approaches to the analysis of interrelated or co-occurring diseases have focused on pairwise associations between diagnoses, missing the higher-order structures that characterise multimorbid patients.

Effective intraoperative speech mapping requires specific test with standardized linguistic material. The last one should capture speech function supported by brain region targeted for resection. It is necessary to develop a test tailored to specific patient’s needs and document intraoperative linguistic support. The objective of this report was to describe the procedure of intraoperative speech testing and battery of intraoperative tests for Russian language. We correlated intraoperative tests with brain regions and speech functions, as well as presented an application ...

Whole-slide histology images (WSIs) can exceed 100 k × 100 k pixels, making direct pixel-level segmentation infeasible and requiring patch-level classification as a practical alternative for downstream WSI segmentation. However, most approaches either treat patches independently, ignoring spatial and biological context, or rely on deep graph models prone to oversmoothing and loss of local tissue ...

Growing evidence suggests the specific systems for emotional information maintenance and processing in working memory, highlighting the role of cognitive domains in emotional awareness. The question of neural basis of social-emotional processing in working memory remains open.

The aim of the present study was to investigate the association between resting-state EEG functional connectivity and spatial working memory (SWM) in adolescents, using a graph-theoretical approach. Sixty-three healthy adolescents (38 females; M = 16.8, SD = 0.47) participated in the study. Resting-state EEG was recorded by a wireless dry-sensor 32-channel headset (Cognionics Quick-32r) configured in a standard 10–20 montage. ...

Alzheimer’s disease (AD) pathogenesis is correlated with the membrane content
of various lipid species, including cholesterol, whose interactions with amyloid precursor
protein (APP) have been extensively explored. Amyloid-β peptides triggering AD are
products of APP cleavage by secretases, which differ depending on the APP and secretase location
relative to ordered or disordered membrane microdomains. We used high-resolution
NMR to probe ...
