Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, Volume 16, Issue 8, Page 809-819, August 2026.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Sex specificity of resistance to caTAUstrophe

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION As amyloid beta (Aβ) accumulates, tau pathology spreads beyond medial temporal lobe (MTL) into neocortical (NEO) regions, though some older adults resist this progression, or what we call here “caTAUstrophe.” Given previous evidence of higher tau levels in women, we tested how tau resistance presented in men and women separately ...

Hormone replacement therapy and its association with LATE‐NC in older adults

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Limbic‐predominant age‐related transactive response DNA‐binding protein 43 (TDP‐43) encephalopathy neuropathological change (LATE‐NC) is a cause of dementia resembling Alzheimer's disease (AD). The 90+ Study found women using hormone replacement therapy (HRT) two to three decades before death had lower odds of LATE‐NC.

Multiscale chemogenetic dissection of fronto-temporal top-down regulation for object memory in primates

Nature Communications
Visual object memory is a fundamental element of various cognitive abilities, and the underlying neural mechanisms have been extensively examined especially in the anterior temporal cortex of primates.

Frequency‐ and Network‐Specific Changes in Functional Connectivity Reflect Pathophysiological Mechanisms across Parkinson's Disease Stages

Annals of Neurology, Volume 100, Issue 2, Page 319-333, August 2026.
Objective Parkinson's disease (PD) is increasingly conceptualized as a disorder of large‐scale brain networks, yet whether and how frequency‐specific functional connectivity reorganizes across stages remains poorly understood. In this study, we used high‐density electroencephalography (EEG) to characterize cortico‐cortical functional connectivity ...

Blunted Reward Responsiveness During Social Feedback: Associations with Peer Victimization and Anhedonia in Socially Anxious Adolescents

Brain and Behavior, Volume 16, Issue 8, August 2026.
Abstract Background The present pilot study aimed to (1) Characterize neural markers of reward sensitivity during periods of social stress; (2) Evaluate clinical relations between neural reward markers and anhedonia; and (3) Investigate if peer victimization was associated with ventral striatum (VS) suppression and anhedonia symptoms during social ...

Regional Functional Molecular Profiles Within the Mammalian Cortex: A Commentary on Limbic Mesocortex

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.
Two lateral mouse brain sagittal sections labeled, respectively, for Lypd1 (A) and Kcnab3 (B). (A) Lypd1 labels positively cortical Layers 2 and 5 (less heavily), but only at limbic mesocortical sites, forming the limbic ring that separates the unlabeled isocortex (IsoCx) from the unlabeled hippocampal and olfactory allocortex (Hi, Sub, ERh; OlfCx ...

Motivational Coaching Cues Can Modulate Prefrontal Cortex Activity and Perceptual Responses of Elite Football Players During High‐Intensity Interval Training: A Randomised Crossover fNIRS Study

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT Football coaches commonly provide verbal encouragement and exercise end‐point feedback to sustain players' effort by enhancing motivation during fitness training such as high‐intensity interval training (HIIT). However, the influence of such cues on the prefrontal cortex (PFC), a region involved in exercise cessation decisions, remains unclear.

Global and Voxel‐Wise Brain Age Prediction Analyses Following Perinatal Stroke

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
ABSTRACT Perinatal stroke affects millions of individuals worldwide, often leading to lifelong complications for those who survive and who require targeted rehabilitation to limit disability. Although biological brain age prediction may be a valuable biomarker to analyze neurodevelopment following perinatal stroke and guide rehabilitation, there have ...

A Discovery and Replication Study of Dyslexia Does Not Reveal Reproducible Gray Matter Volume Differences

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
This study shows that gray matter volume (GMV) differences in dyslexia fail to replicate across two studies in large, representative samples, and reproducibility of results is dependent on analytic choices, particularly whether total GMV is accounted for. Prior GMV findings in dyslexia should therefore be considered with caution.
