To investigate the effects of monotonous daytime driving on vigilance state and particularly the ability to judge this state, a real road driving study was conducted. To objectively assess vigilance state, performance (auditory reaction time) and physiological measures (EEG: alpha spindle rate, P3 amplitude; ECG: heart rate) were recorded continuously. Drivers judged sleepiness, attention to the driving task and monotony retrospectively every 20 min. Results showed that prolonged daytime driving under monotonous conditions leads to a continuous reduction in vigilance. Towards the end of the drive, drivers reported a subjectively improved vigilance state, which was contrary to the continued decrease in vigilance as indicated by all performance and physiological measures. These findings indicate a lack of self-assessment abilities after approximately 3h of continuous monotonous daytime driving.

Context: Worldwide, obesity remains one of the most challenging crises with children being one of the most susceptible populations. The effect of maternal stress during pregnancy on newborn body composition, measured by fat mass and lean mass has, not been extensively studied.
Objectives: We evaluated the association between perceived stress during late pregnancy and infant adiposity at 1 month and assessed effect modification by infant sex and preterm birth.

Background: Social behavioral research studies have increasingly shifted to remote recruitment and enrollment procedures. This shifting landscape necessitates evolving best practices to help mitigate the negative impacts of deceptive attempts (eg, fake profiles and bots) at enrolling in behavioral research.
Objective: This study aimed to develop and implement robust deception detection procedures during the enrollment period of a remotely conducted randomized controlled trial.

Objective: Disorders of arousal (DoA) are characterized by an intermediate state between wakefulness and deep sleep, leading to incomplete awakenings from NREM sleep. Multimodal studies have shown subtle neurophysiologic alterations even during wakefulness in DoA. The aim of this study was to explore the brain functional connectivity in DoA and the metabolic profile of the anterior and posterior cingulate cortex, given its pivotal role in cognitive and emotional processing.

Lyme neuroborreliosis can present with isolated neurological manifestations, posing diagnostic challenges, especially in the absence of hallmark dermatological symptoms like erythema migrans. This case highlights a patient with isolated cervical radiculopathy due to Lyme neuroborreliosis, presenting without systemic features such as fever, arthralgia, or rash. The diagnosis was confirmed through serological testing, with positive findings on the Western blot.

The nonimage-forming effects of light are pivotal in regulating cognitive functions, including alertness, sustained attention, and higher-order cognitive processes. These cognitive domains are deeply influenced by the sleep-wake cycle, which are governed by two key processes: the homeostatic process, which builds sleep pressure during wakefulness, and the circadian process, which aligns with environmental light cues to regulate wakefulness and sleep. When these processes fall out of sync-a condition known as circadian misalignment-alertness, sustained attention, and cognitive performance can suffer significantly.
