Common stressors amongst postsecondary students are exam-induced anxiety and stress. The purpose of this study was to measure stress alterations in the student population around examinations and determine how they affect electroencephalogram (EEG) profiles and memory scores. Twenty university students were measured multiple times in the study. During each measurement, participants were administered a cortisol saliva test and an EEG. We hypothesized that cortisol levels, memory scores, and EEG profiles would all demonstrate changes near examinations. The brain regions of interest (ROIs) were the parahippocampal gyrus, the medial frontal gyrus, and the middle frontal gyrus. Results demonstrated that memory performance and parahippocampal activity were correlated, specifically in the 5–9 Hz frequency band. Correlations were also computed between cortisol levels, memory performance, and parahippocampal activity. The medial frontal gyrus also displayed changes in the mean (19–20 Hz) current source density (CSD) throughout the experiment. The middle frontal gyrus activation was highly variable during the different measurement time points. Essentially, when an individual’s memory scores were consistent between exam and nonexam trials, there was an increase in middle frontal gyrus activation during examination periods. Lastly, the right parahippocampal gyrus was found to be the most activated one day away from examination time. These results indicate that memory scores are related to cortisol levels and examination periods, but most importantly, there are overt and predictable alterations in student EEG profiles near examinations.

Some species of fish show highly evolved mechanisms by which they can detect exogenous electric and magnetic fields. The detection of electromagnetic fields has been hypothesized to exist in humans, despite the lack of specialized sensors. In this experiment, planaria were tested in a t-maze with weak electric current pulsed in one arm to determine if the planaria showed any indication of being able to detect it. It was found that a small proportion of the population seemed to be attracted to this current. Additionally, if the experiment was preceded by a geomagnetic storm, the planaria showed a linear correlation increase in the variability of their movement in response to the presence of the weak electric field. Both of these results indicate that a subpopulation of planaria show some ability to respond to electromagnetic fields.

Background: Patient navigation is a critical component of health care delivery, facilitating connections with appropriate services. A new era of virtual navigation systems has emerged, with systems that can be accessed through websites or smartphone apps. However, it is unknown which features of these novel systems impact patient outcomes. Objective: The objective of this scoping review is to understand the current landscape of existing virtual navigation systems. In this review, we will determine the features of these systems, as well as the patient outcomes and accessibility barriers associated with them that have been reported in the literature. Methods: This review will follow the guidelines for scoping reviews outlined by the Joanna Briggs Institute methodology. This will include systems that provide recommendations for health care, mental health and addiction services, and social services. This will include systems designed for patients, caregivers, and/or care providers. A search strategy will be used to locate both published and unpublished literature. The databases to be searched include PubMed, PsycINFO (ProQuest), Cochrane Library, Web of Science Core Collection (Clarivate), Cumulative Index of Nursing and Allied Health Literature (EBSCO), ScienceDirect, IEEE Xplore, and ACM Digital Library. Papers will be screened and selected, and data will be extracted by 2 independent members of the research team. The extracted data will primarily focus on outcomes and features of the virtual navigation systems. This will include the information they ask of users and the content and format of the information on services they provide. Results: Funding for this project was received in May 2024. As of June 2026, abstract and full-text screening have been completed, data extraction is underway, and data analysis has not begun yet. Our search resulted in the retrieval of 14,461 studies that were eligible for screening. We anticipate that the full scoping review manuscript will be prepared for submission by winter 2027. Results will be presented in tabular format and accompanied by a narrative summary. Conclusions: This review will synthesize the current literature on virtual navigation systems that aim to connect patients to appropriate health care services. By identifying trends and gaps, this review will provide critical information for the development of new and innovative systems that can support health care and public health systems.

BACKGROUND Patient navigation is a critical component of health care delivery, facilitating connections with appropriate services. A new era of virtual navigators are being developed that can be accessed through the web or smartphone application. However, it is unknown what features make virtual navigators accessible and reliable. OBJECTIVE The objective of this scoping review is to understand the current landscape of existing virtual navigation systems. In this review we will determine the features of these systems and barriers to accessibility they’ve identified. METHODS This review will follow the guidelines for scoping reviews outlined by the Joanna Briggs Institute (JBI) methodology. A search strategy will be used to locate both published and unpublished literature. The databases to be searched include PubMed, PsycINFO (ProQuest), Cochrane Library, Web of Science Core Collection (Clarivate), Cumulative Index of Nursing and Allied Health Literature (EBSCO), ScienceDirect, IEEE Xplore, and ACM Digital Library. Articles will be screened, selected, and extracted by 2 independent members of the research team. Results will be presented in table format and accompanied by a narrative summary. RESULTS As of September 2025, the preliminary stages of the scoping review have been completed. We anticipate the full scoping review manuscript will be prepared for submission by February 2026. CONCLUSIONS This review will synthesize the current literature of virtual navigation tools and recommendations systems that aim to connect users to the appropriate health care services. By identifying trends and gaps, this review will provide critical information for the development of new and innovative systems that can support healthcare and public health systems.
