Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Locus Coeruleus-Norepinephrine System: Spheres of Influence and Contribution to the Development of Neurodegenerative Diseases

Frontiers in Bioscience-Landmark
Locus coeruleus is a small bilateral nucleus in the brainstem. It is the main source of norepinephrine (noradrenaline) throughout the central nervous system (about 70% of all norepinephrine in the central nervous system), and, as shown in numerous ...

The locus coeruleus

Alzheimer’s disease is a common form of dementia that impairs memory and thinking, usually later in life. Years before symptoms appear, harmful proteins start to build up in the brain. This early phase, called the preclinical stage, offers an opportunity to detect and address the disease before significant damage occurs.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Modulating cortical excitability and cortical arousal by pupil self-regulation

Nature Communications
The brain’s arousal state (i.e., central arousal) is regulated by multiple neuromodulatory nuclei in the brainstem and significantly influences high-level cognitive processes.

Lesions of the locus coeruleus system aggravate ischemic damage in the rat brain

, 1985
The possibility that the noradrenergic locus coeruleus system influences brain damage following ischemia was explored in rats. Bilateral lesions of the locus coeruleus projections to the forebrain aggravated the neuronal necrosis in the hippocampal CAI ...

An Investigation of Sleep Macro‐ and Microarchitecture by APOE Genotype

Annals of Neurology, Volume 100, Issue 5, Page 1012-1022, November 2026.
Objectives Apolipoprotein E ε4 (APOE ε4), a robust genetic risk factor for Alzheimer's disease (AD) is associated with functional connectivity deficits and amyloid pathology in brain regions involved in sleep regulation. Thus, alterations in sleep architecture may be one pathway through which ε4 contributes to Alzheimer's disease vulnerability. However,

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches

Analysis &Sensing, Volume 6, Issue 6, November 2026.
The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,

Opioid withdrawal syndrome‐associated cognitive impairment: A narrative review

The American Journal on Addictions, Volume 35, Issue 6, Page 661-672, November 2026.
Abstract Background and Objectives Opioid withdrawal syndrome (OWS) comprises a transient constellation of subjective symptoms and objective signs expressed by brain and other organs. Although cognitive impairment is well documented in opioid use and addiction, little is known about cognitive impairment that may specifically accompany OWS.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, Volume 36, Issue 6, November 2026.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive
