Article Abstract
Spreading depression (SD), a pathological cortical negative DC potential, is caused by an elevation of potassium ions in the extracellular space. This leads to a transient relocation of ions within neurons and a slow spread through brain tissue. Our previous research established a correlation between scalp SD and seizures in patients with intractable epilepsy using our novel electroencephalography (EEG). In this study, we enhanced our EEG system by incorporating a Near-infrared spectroscopy (NIRS) module for multi-modal EEG-NIRS measurements. The aim is to provide an investigation into the defining characteristics and methods for detecting SD.Clinical Relevance-: The detection of SD serves as a novel biomarker for epilepsy, capable of forewarning seizures within a time range from 10 secs to 30 min. This detection plays a crucial role in predicting and preventing seizures and providing diagnostic information for drug-resistant epilepsy patients.

Cortical spreading depolarization (depression) underlies migrainous aura and is posited to cause its headache. At times, aura may start before headache, auras may start at the same time as, or shortly after headache onset, or sometimes without any headache at all. We suggest that the extent of spread and not the spread limited to eloquent cortex, is the key variable in the genesis of headache.

Background: Opioid-free analgesia is critical in pediatric patients with complex comorbidities to avoid adverse effects, such as respiratory depression. Patients with tethered cord syndrome (TCS), often presenting with conditions like spina bifida, renal impairment, and musculoskeletal deformities, pose unique perioperative challenges that demand alternative pain management strategies.
Case: We present the case of an 11-year-old male with spina bifida and chronic kidney disease (CKD) undergoing tethered cord release surgery.

Background: Understanding the mechanisms of pathological brain network activity and the efficacy of therapies requires testing hypothesis in vivo, where brain circuitry remains preserved. Therefore, animal models are a key tool in the study of primary neurological disorders such as migraine, stroke and epilepsy. These models not only have advanced our understanding of the underlying neurobiology of these disorders but have also provided novel pharmacological targets and insights on shared pathophysiological processes such as spreading depolarizations (SD).

Migraine is a prevalent neurological disorder that affects over 1 billion individuals worldwide. The pathogenesis of migraine remains incompletely understood, though evidence suggests a multifactorial etiology involving genetic factors. The gene has been implicated in rare forms of Familial Hemiplegic Migraine (FHM).
