OBJECTIVES: This study aimed to analyse if children with untreated or treated caries (restorations/missing teeth) are perceived differently compared to children with healthy teeth and to explore possible differences in the perception by laypersons and dental experts. METHODS: Eye movements of female experts (n = 20) and laypersons (n = 18) were recorded by eye-tracking while paired images (neutral expression/teeth not visible; emotional expression/smiling, teeth visible) of children with healthy teeth, with visible untreated or treated caries (restorations/missing teeth as a consequence of caries treatment), each n = 13, were presented...

Alexithymia refers to difficulties in identifying, differentiating, and describing feelings. This personality trait is highly prevalent in many psychiatric conditions and may drive associated social-emotional problems, including the ability to decode emotions in faces. This study probed alexithymic problems with identifying clear and ambiguous blends of emotions in faces and their underlying visual attention patterns. Using the Toronto Alexithymia Scale-20, students with high alexithymia (HA, n = 73) or low alexithymia (LA, n = 76) were enrolled in this study...

The medullary reticular formation (RF) is involved in the maintenance of several vital physiological functions and level of vigilance. In the present study in non-anesthetized, head-fixed mice, I examined the role of medullary RF neurons in the control of sleep-wake states, i.e. wakefulness (W), slow-wave sleep (SWS), and paradoxical (or rapid eye movement) sleep (PS). I showed, for the first time, that the mouse medullary RF contains presumed SWS-promoting, SWS-on neurons that remain silent during W, display a sharp increase in discharge rate at sleep onset, and discharge tonically and selectively during SWS...

Study Objectives : To assess whether biopsy of the labial minor salivary glands safely detects phosphorylated alpha-synuclein (pAS) deposits in idiopathic REM sleep behavior disorder (IRBD), a condition that precedes the cardinal manifestations of synuclein disorders associated with Lewy type pathology, namely Parkinson disease (PD) and dementia with Lewy bodies (DLB). Methods: In a prospective study, labial biopsy of the minor salivary glands was performed in 62 IRBD patients, 13 PD and 10 DLB patients who were initially diagnosed with IRBD, and in 33 controls...

SIGNIFICANCE: New bitangential mini-scleral lens designs provide a highly precise fit, follow the scleral shape, are comfortable to wear, and can correct residual astigmatism. This new scleral lens design complements the arsenal of medical contact lenses available to eye care practitioners. PURPOSE: The aim of this study was to evaluate the subjective and objective performance of a new mini-scleral lens design with a bitangential periphery. METHODS: In this observational study, data were collected for up to 15 months (median, 84 days; interquartile range, 76 days) from the left eyes of 133 patients fitted with this newly designed lens...

SIGNIFICANCE: Prior studies have demonstrated the effectiveness of vergence-accommodative therapy in the treatment of convergence insufficiency (CI). These results show the changes in brain activation following therapy through the use of functional magnetic resonance imaging (fMRI). PURPOSE: The purpose of this study was to investigate changes in brain activation following office-based vergence-accommodative therapy versus placebo therapy for CI using the blood oxygenation level-dependent signal from fMRI...

Introduction: Precision of movements responsible for maintaining balance deteriorates with age due to natural involutionary processes, thus prompting a research question whether the values of gender-related stability indicators might differ significantly among the study subjects over 60 years of age. Methods: The study group comprised 136 seniors (89 women, 47 men; aged 60-90 years). The CQ-Stab 2P 2-platform posturograph was used as the main research device, whereas the Mann-Whitney U -test was used to evaluate the gender-related differences in the average level of variables...

Can hazard perception testing be useful for the emergency services? Previous research has found emergency response drivers' (ERDs) to perform better than controls, however these studies used clips of normal driving. In contrast, the current study filmed footage from a fire-appliance on blue-light training runs through Nottinghamshire, and endeavoured to discriminate between different groups of EDRs based on experience and collision risk. Thirty clips were selected to create two variants of the hazard perception test: a traditional push-button test requiring speeded-responses to hazards, and a prediction test that occludes at hazard onset and provides four possible outcomes for participants to choose between...

BACKGROUND: Saccadic eye movements are controlled by a network of parietal, frontal, striatal, cerebellar and brainstem regions. The saccadic peak velocity is an established biomarker of benzodiazepine effects, with benzodiazepines reliably reducing the peak velocity. AIMS: In this study, we aimed to replicate the effects of benzodiazepines on peak velocity and we investigated effects on previously less studied measures of saccades. We also explored the roles of sex, task characteristics and the baseline variables age, intelligence and trait anxiety in these effects...

PURPOSE: Sight-threatening injuries associated with orbital fractures are of major concern to maxillofacial surgeons whom are often the first asked to assess these patients. Eliciting signs and symptoms that are predictive of these injuries would allow expedited ophthalmic consultation and appropriate management. We hypothesized that abnormal pupillary response is predictive of major ocular injuries. PATIENTS AND METHODS: A retrospective cohort study of patients with facial fractures was instituted with review of all associated ophthalmic injuries...

Age-related reading difficulty is well established for alphabetic languages. Compared to young adults (18-30 years), older adults (65+ years) read more slowly, make more and longer fixations, make more regressions, and produce larger word-frequency effects. However, whether similar effects are observed for nonalphabetic languages like Chinese remains to be determined. In particular, recent research has suggested Chinese readers experience age-related reading difficulty but do not produce age differences in the word-frequency effect...

Purpose: To report the case of a patient with Crystalens, an accommodating posterior-chamber intraocular lens (IOL), who experienced a myopic shift following subsequent vitrectomy with gas tamponade. We propose a hypothesis as to why this myopic shift occurred and analyze its validity based on current literature. Observations: A patient had cataract surgery with implantation of a Crystalens AT-50AO +21D. Preoperative A-scan measured anterior chamber depth (ACD) to be 3...

Purpose: To report management of inadvertent needle penetration during subtenons triamcinolone acetonide administration resulting in retinal detachment. Observations: A 71-year-old female with history of diabetes, hypothyroidism, and mild myopia underwent subtenons triamcinolone acetonide (TA) injection in the right eye for nodular scleritis. There was unexpected patient movement concurrent with the injection resulting in needle penetration, subretinal and intravitreal injection of TA, superotemporal retinal break, and macula-involving retinal detachment...

Network hyperexcitability is a feature of Alzheimer' disease (AD) as well as numerous transgenic mouse models of AD. While hyperexcitability in AD patients and AD animal models share certain features, the mechanistic overlap remains to be established. We aimed to identify features of network hyperexcitability in AD models that can be related to epileptiform activity signatures in AD patients. We studied network hyperexcitability in mice expressing amyloid precursor protein (APP) with mutations that cause familial AD, and compared a transgenic model that overexpresses human APP (hAPP) (J20), to a knock-in model expressing APP at physiological levels (APPNL/F )...

Focal segmental glomerulosclerosis (FSGS) is a leading cause of end-stage renal disease in children and adults. Genetic factors significantly contribute to early-onset FSGS, but the etiologies of most adult cases remain unknown. Genetic studies of monogenic syndromic FSGS exhibiting extra-renal manifestations have uncovered an unexpected biological role for genes in the development of both podocytes and other cellular lineages. To help define these roles, we studied two unrelated families with FSGS associated with Duane Retraction Syndrome, characterized by impaired horizontal eye movement due to cranial nerve malformation...

OBJECTIVE: As connections between nightmares and various psychiatric disorders have been reported, the clinical significance of studying dream emotionality is now growing in importance. Because the olfactory bulb connects directly to the amygdala odor presentation may be a crucial tool to study dream emotions. Previous studies have demonstrated that presentation of positive/negative odors during rapid eye movement (REM) sleep affects various aspects of dreaming. Although olfactory perception can be influenced by personal experiences, the role of individual preferences in the effects of olfactory stimuli on dreaming has not yet been clarified...

BACKGROUND: Duane syndrome is a congenital eye movement disorder characterized by congenital malformation of the abducens nucleus. Thrombogenic conditions during development may lead to vascular anomalies in Duane syndrome, however, the presence of a giant aneurysm in this patient population is a rarely documented phenomenon. CASE DESCRIPTION: We reported a case of a large cerebral aneurysm in a pediatric patient with Duane syndrome, and performed a review of the literatures to identify other potential cases and associations...

REVIEW
Penelope A Lewis, Günther Knoblich, Gina Poe
Creative thought relies on the reorganisation of existing knowledge. Sleep is known to be important for creative thinking, but there is a debate about which sleep stage is most relevant, and why. We address this issue by proposing that rapid eye movement sleep, or 'REM', and non-REM sleep facilitate creativity in different ways. Memory replay mechanisms in non-REM can abstract rules from corpuses of learned information, while replay in REM may promote novel associations. We propose that the iterative interleaving of REM and non-REM across a night boosts the formation of complex knowledge frameworks, and allows these frameworks to be restructured, thus facilitating creative thought...
