The Neural Correlates of Body Image Processing in Anorexia Nervosa and Bulimia Nervosa: An Activation Likelihood Estimation Meta-Analysis of fMRI Studies.

Body image concerns are key prognostic and pathogenic factors of anorexia nervosa (AN) and bulimia nervosa (BN). This study aimed to investigate the neural mechanisms underlying body image perception across its two domains of estimation and satisfaction in anorexia and bulimia patients and healthy controls (HC). Systematic searches were conducted across eight databases, including PubMed; Cochrane Library; Ovid; Google Scholar; Sage Journals; Scopus; PsycInfo; and ScienceDirect, from database inception until the 23rd of April 2023.

Organization of the stalk system on electrocytes in mormyrid weakly electric fish Campylomormyrus compressirostris.

The adult electric organ in weakly electric mormyrid fish consists of action-potential-generating electrocytes, structurally and functionally modified skeletal muscle cells. The electrocytes have a disc-shaped portion and, on one of its sides, numerous thin processes, termed stalklets. These unite to stalks leading to a single main stalk that carries the innervation site.

A comparison of recall methods for high-stress critical incidents in police training.

Police officers often face critical incidents involving armed offenders, requiring the use of force to ensure safety. Eyewitness accounts, including those from officers, are crucial in the justice system but can be unreliable. Techniques such as self-authored statements and structured interviews are used to gather information, but their efficacy in high-stress situations is unclear.

A Systematic Review on the Prevalence and Risk of Orthorexia Nervosa in Health Workers and Students.

Extensive knowledge on nutrition and dieting has been associated with an increased risk of orthorexia (an obsession with food that one considers healthy) within the research literature. A systematic review was conducted to identify the prevalence of orthorexia in individuals who were employed in, or studying, health careers. The databases Psychinfo and Pubmed were searched to obtain research articles.

Spatial arrangement, polarity, and posttranslational modifications of the microtubule system in the Drosophila eye.

We have analyzed the organization of the microtubule system in photoreceptor cells and pigment cells within the adult Drosophila compound eye. Immunofluorescence localization of tubulin and of Short stop, a spectraplakin that has been reported to be involved in the anchorage of microtubule minus ends at the membrane, suggests the presence of non-centrosomal microtubule-organizing centers at the distal tip of the visual cells. Ultrastructural analyses confirm that microtubules emanate from membrane-associated plaques at the site of contact with cone cells and that all microtubules are aligned in distal-proximal direction within the photoreceptor cells.

Could Nature Contribute to the Management of ADHD in Children? A Systematic Review.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that is typically managed with pharmacological and psychotherapeutic interventions. In the general population, exposure to nature has been found to have robust beneficial effects on cognitive performance, including attention. With inattention being a factor of the symptomatology of individuals with ADHD, this provides a rationale to investigate the potential benefits of exposure to nature for this population.

The impact of room shape on affective states, heartrate, and creative output.

The architectural design of space can deeply impact an individuals' mood, physiology, and mental health. While previous research has predominantly focused on elements like nature and lighting within architectural spaces, there is a growing literature base that also investigates the psychological and neurophysiological impacts of geometrical properties of architectural spaces. Employing virtual reality technology, the study sought to investigate the effects of curved and rectangular architectural spaces on affective states, heart rate, and creativity.

Gene and Allele-Specific Expression Underlying the Electric Signal Divergence in African Weakly Electric Fish.

In the African weakly electric fish genus Campylomormyrus, electric organ discharge signals are strikingly different in shape and duration among closely related species, contribute to prezygotic isolation, and may have triggered an adaptive radiation. We performed mRNA sequencing on electric organs and skeletal muscles (from which the electric organs derive) from 3 species with short (0.4 ms), medium (5 ms), and long (40 ms) electric organ discharges and 2 different cross-species hybrids.

The Effectiveness of Adolescent-Focused Therapy and Family-Based Therapy for Anorexia Nervosa.

Anorexia Nervosa is the most deadly mental illness due to the high mortality and relapse rates after reaching remission. The systematic review investigated the effectiveness of two empirically validated interventions (Family-Based Therapy [FBT] and Adolescent-Focused Therapy [AFT]) for an adolescent or young adult living with Anorexia Nervosa to reach partial or full remission and expected weight ratios. Twelve studies published between 1994 and 2015 were evaluated and indicated that FBT resulted in significant weight gain and higher partial and full remission rates than AFT, demonstrating its superiority in treating AN in adolescents and young adult samples, in one instance, at least up to 4 years.

Test-retest reliability of spectral parameterization by 1/f characterization using SpecParam.

SpecParam (formally known as FOOOF) allows for the refined measurements of electroencephalography periodic and aperiodic activity, and potentially provides a non-invasive measurement of excitation: inhibition balance. However, little is known about the psychometric properties of this technique. This is integral for understanding the usefulness of SpecParam as a tool to determine differences in measurements of cognitive function, and electroencephalography activity.

Medication-invariant resting aperiodic and periodic neural activity in Parkinson's disease.

Parkinson's disease (PD) has been associated with greater total power in canonical frequency bands (i.e., alpha, beta) of the resting electroencephalogram (EEG).

Motivation moderates gender differences in navigation performance.

Gender differences in navigation performance are a recurrent and controversial topic. Previous research suggests that men outperform women in navigation tasks and that men and women exhibit different navigation strategies. Here, we investigate whether motivation to complete the task moderates the relationship between navigation performance and gender.

Use of extended reality in sleep health, medicine, and research: a scoping review.

Study Objectives: This scoping review explores the use of extended reality (virtual, augmented, and mixed reality) within sleep health, sleep medicine, and sleep research. It aims to provide insight into current uses and implementation considerations whilst highlighting directions for future research.

Methods: A systematic scoping review was undertaken informed by the preferred reporting items for systematic reviews and meta-analyses for scoping reviews and Johanna Briggs Institute.

Extended Reality Use in Paediatric Intensive Care: A Scoping Review.

Extended reality (XR) technology such as virtual and augmented reality is increasingly being utilised in paediatric medicine due to its role in medical education and reported positive impacts on outcomes including pain, anxiety, and sleep. To the author's knowledge, no previous reviews investigating the use of XR in paediatric intensive care have been undertaken. To scope the use of XR in paediatric intensive care, and assess its barriers to adoption, including safety considerations, cleaning and infection control.

Multimodal assessment of effects of urban environments on psychological wellbeing.

The built environment is a ubiquitous factor of modern human life, which fundamentally affects human wellbeing. Most existing research on the psychological effects of urban environments is predominantly based on subjective self-report measures, which provide valuable insights into subjective experiences, but are also affected by conscious and subconscious bias. In the current study, we evaluate a multimodal approach to capturing wellbeing by employing objective mobile physiological and neurophysiological measurement technologies alongside self-reports to capture the impact of two different urban environments.

Psychological mechanisms and interventions directed at vaccination attitudes.

Attitudes about vaccination impact not only the individual but also society. Therefore, understanding the underlying psychological processes of those who disagree with vaccination is critical for creating compassion through understanding and change through promoting autonomy. The current review aimed to fill a gap in the literature, outlining the state of the recent research on vaccination attitudes, specifically on the underlying mechanisms driving anti-vaccination movements and individuals' thoughts and behaviors.

Predictors of concussion reporting intentions in adolescent hockey players.

Young athletes who do not report a concussion injury are at greater risk for a prolonged recovery time and further neurocognitive impairments. Despite the seriousness of the issue and the scale of the problem, not enough is known about the behavioural underpinnings of concussion underreporting in minor athletes. This paper aims to apply the Knowledge, Attitude, and Behaviour (KAB) framework to the issue of injury reporting in adolescents, with the specific purpose of exploring to which degree concussion knowledge, concussion attitudes, and gender affect concussion reporting intentions of both male and female athletes.

Neuroimaging Correlates of Cognitive Behavioral Therapy for Insomnia (CBT-I): A Systematic Literature Review.

Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard non-pharmacological treatment for insomnia, a complex disorder that comprises psychological, behavioral, and physiological components. This systematic literature review aimed to evaluate a growing body of exploratory studies that have examined CBT-I treatment effects using neuroimaging assessment. Nine studies met current review selection criteria, of which six studies compared insomnia groups with good sleepers, waitlist, and/or control groups.

Intuitive teaching of medical device operation to clinical assistance robots.

Purpose: The adjustment of medical devices in the operating room is currently done by the circulating nurses. As digital interfaces for the devices are not foreseeable in the near future and to incorporate legacy devices, the robotic operation of medical devices is an open topic.

Methods: We propose a teleoperated learning from demonstration process to acquire the high-level device functionality with given motion primitives.

Does path integration contribute to human navigation in large-scale space?

Path integration is a process in which navigators estimate their position and orientation relative to a known location by using body-based internal sensory cues that arise from navigation-related bodily motion (e.g., vestibular and proprioceptive signals).

EcoMeditation Modifies Brain Resting State Network Activity.

Background: The tendency of the mind to wander, a characteristic of the brain's default mode network (DMN), correlates with increased unhappiness and self-referential processing and is a deterrent to establishing a consistent meditation practice. The objective of this study was to test the impact of a secular physiological method of meditation. We hypothesized that EcoMeditation would produce increases in neural communication in brain regions associated with compassion and prosociality and decreases in self-referencing networks, such as the DMN, and that these changes would be found in the experimental group, but not the control group.

Mobile service robots for the operating room wing: balancing cost and performance by optimizing robotic fleet size and composition.

Purpose: Integrating fleets of mobile service robots into the operating room wing (OR wing) has the potential to help overcome staff shortages and reduce the amount of dull or unhealthy tasks for humans. However, the OR wing has been little studied in this regard and the requirements for realizing this vision have not yet been fully identified. This includes fundamental aspects such as fleet size and composition, which we have now studied comprehensively for the first time.

Cerebellum and Emotion Processing.

Clinical examinations and neuroimaging investigations have dramatically changed the prevailing view of human cerebellar function and suggest contributions beyond movement control. Of these new views, perhaps the most intriguing proposal is that the cerebellum plays a key role in regulating emotion. According to the dysmetria of thought theory, the cerebellum provides accuracy, consistency and appropriateness to cognitive and affective functions, as it does for movement-related operations.
