Dopaminergic novelty detection and theta oscillations: Virtual reality‐based adaptive interventions for cognitive enhancement in aging

Ibrain, EarlyView.
Aging‐related cognitive decline is associated with reduced dopaminergic signaling and disrupted theta oscillations, which together impair novelty detection and memory formation. This review shows how VR environments can be used to deliver adaptive, novelty‐rich stimuli that engage dopaminergic circuits and entrain theta rhythms, thereby enhancing ...

EEG and ECG Microstructure Markers During Apnea Transition Phases in Central and Obstructive Sleep Apnea

Gazi Üniversitesi Fen Bilimleri Dergisi
This study aimed to characterize EEG- and ECG-derived microstructural markers during apnea transitions in central sleep apnea (CSA) and obstructive sleep apnea (OSA), and to examine how these transient dynamics vary across sleep stages and apnea severity.

Vegetative and endocrine predictors of individual immune responses to adaptogenic balneotherapy

Journal of Education, Health and Sport, 2020
Background. Earlier four variants of the immune responses to adaptogenic balneotherapy have been identified. All four variants of immune responses are virtually unmistakably predicted by a set of 20 predictors including 12 immune blood parameters and one

Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

A Methodological Framework to Study Change in Team Cognition Under the Dynamical Hypothesis

Topics in Cognitive Science, EarlyView., 2023
Abstract The dynamical hypothesis claims that cognitive systems, such as teams, are dynamical systems (i.e., an interdependent collection of individuals and their technology that change together over time). Following this hypothesis, team researchers have adopted dynamical approaches to better understand the team cognitive processes and states that ...
