Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

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 ...

The Role of Astrocytes in Migraine with Cortical Spreading Depression: Protagonists or Bystanders? A Narrative Review

Pain and Therapy
Cortical spreading depression (CSD) is a slow wave of cortical depolarization closely associated with migraines with an aura. Previously, it was thought that CSD depolarization was mainly driven by neurons, with characteristic changes in neuronal ...

Simultaneous mesoscopic imaging of neural activity and hemodynamics reveals anesthetic modulation of neurovascular responses

Photoacoustics
Anesthesia substantially alters neural activity and vascular tone, yet its state-dependent modulation of cortical neurovascular coupling (NVC) remains incompletely characterized.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Neuro-ophthalmology and migraine: visual aura and its neural basis

International Journal of Emergency Medicine
Background Migraine, a chronic neurological condition often accompanied by visual aura, which affects 15–33% of migraineurs, often presents as transient visual disturbances such as scintillating scotoma and teichopsia. These symptoms arise primarily from

High‐altitude headache: Insights into pathophysiology and potential treatment implications

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude headache occurs during prolonged exposure to low oxygen, such as during ascent to high altitude. Several risk factors increase its likelihood, with the degree of hypoxia, often driven by rapid ascent to greater altitudes, being the most prominent factor.
