The Locus Coeruleus- Norepinephrine System in Stress and Arousal: Unraveling Historical, Current, and Future Perspectives

open access: yesFrontiers in Psychiatry, 2021
Arousal may be understood on a spectrum, with excessive sleepiness, cognitive dysfunction, and inattention on one side, a wakeful state in the middle, and hypervigilance, panic, and psychosis on the other side.

The Diagnostic Value of Visual Evoked Potentials in Chronic Disorders of Consciousness

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In chronic disorders of consciousness (DOCs), the distinction between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) is as crucial as it is challenging. Evoked potentials (EPs) and event‐related potentials (ERPs) are helpful, but some limitations prevent their consistent use in the ...

The Impact of Context on Affective Norms: A Case of Study With Suspense

open access: yesFrontiers in Psychology, 2019
The emotional response to a stimulus is typically measured in three variables called valence, arousal and dominance. Based on such dimensions, Bradley and Lang (1999) published the Affective Norms for English Words (ANEW), a corpus of affective ratings ...

Effects of Cognitive Arousal and Physiological Arousal on Sleep Perception [PDF]

open access: yesSleep, 2004
Two experiments were conducted to investigate the effect of presleep arousal on sleep perception. Experiment 1 examined the link between presleep cognitive arousal and distorted perception of sleep and compared the relative effect of anxious and neutral cognitive arousal on sleep perception.

Untangling the Role of Capping Agents in Manipulating Electrochemical Behaviors Toward Practical Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Inspired by the critical role of capping agents in nanomaterials synthesis and bulk crystal growth, the role of capping agents in manipulating the electrochemical behaviors of AZIBs is untangled. The multifunctional role of the capping agents in terms of the Zn anode, electrolyte, and cathode validates stable and practical AZIBs. Abstract Long‐standing

Free-Energy Model of Emotion Potential: Modeling Arousal Potential as Information Content Induced by Complexity and Novelty

open access: yesFrontiers in Computational Neuroscience, 2021
Appropriate levels of arousal potential induce hedonic responses (i.e., emotional valence). However, the relationship between arousal potential and its factors (e.g., novelty, complexity, and uncertainty) have not been formalized.

Arousal and drug abuse [PDF]

open access: yesBehavioural Brain Research, 2017
The reticular activating system (RAS) is not an amorphous region but distinct nuclei with specific membrane properties that dictate their firing during waking and sleep. The locus coeruleus and raphe nucleus fire during waking and slow wave sleep, with the pedunculopontine nucleus (PPN) firing during both waking and REM sleep, the states manifesting ...

Pioneering the Future: Principles, Advances, and Challenges in Organic Electrodes for Aqueous Ammonium‐Ion Batteries

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Leveraging the numerous advantages of ammonium‐ion (NH₄⁺)—including cost‐effectiveness, low corrosiveness, preferential orientation, and rapid diffusion kinetics—aqueous NH₄⁺ batteries (AAIBs) have gained significant attention. This review highlights and evaluates the progress of AAIBs utilizing organic electrode materials such as small molecules ...

The Origins of Passive, Active, and Sleep-Related Fatigue

open access: yesFrontiers in Neuroergonomics, 2021
Driving is a safety-critical task that requires an alert and vigilant driver. Most research on the topic of vigilance has focused on its proximate causes, namely low arousal and resource expenditure.
