Phasic Firing in Vasopressin Cells: Understanding Its Functional Significance through Computational Models [PDF]

, 2012
Vasopressin neurons, responding to input generated by osmotic pressure, use an intrinsic mechanism to shift from slow irregular firing to a distinct phasic pattern, consisting of long bursts and silences lasting tens of seconds.

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

British Journal of Pharmacology, Volume 183, Issue 7, Page 1313-1340, April 2026.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

The dopamine D1-D2 receptor heteromer in striatal medium spiny neurons: evidence for a third distinct neuronal pathway in basal ganglia

Frontiers in Neuroanatomy, 2011
Dopaminergic signaling within the basal ganglia has classically been thought to occur within two distinct neuronal pathways; the direct striatonigral pathway which contains the dopamine D1 receptor and the neuropeptides dynorphin and substance P, and the

Contemporary and Emerging Therapies in the Management of Refractory Angina: A Clinical Review

Catheterization and Cardiovascular Interventions, Volume 107, Issue 4, Page 869-884, March 1, 2026.
ABSTRACT Refractory angina (RA) represents a growing challenge in clinical cardiology, particularly in patients with obstructive coronary artery disease (CAD) who remain symptomatic despite optimal medical therapy and who are not candidates for revascularization.

Effects of a kappa opioid receptor antagonist on delayed postoperative pain recovery in a novel mouse sleep disorder model

Frontiers in Pain Research
IntroductionSleep disturbances have been shown to exacerbate pain sensitivity and prolong recovery from pain. However, conventional animal models of sleep disturbance, which involve physical disruptions, such as water or forced movement, might not fully ...

Fetal Pain Perception: Legislative Assertions and Developmental Neuroscience

Annals of the Child Neurology Society, Volume 4, Issue 1, Page 15-28, March 2026.
ABSTRACT Background Pain perception is a conscious experience, but neither pain nor consciousness is defined in the developing human fetus. Emergent consciousness may be regarded as a phenomenon that ultimately arises from an essential minimum of functional neuronal connectivity. Proposed U.S.

Low Degree of Overlap Between Kisspeptin, Neurokinin B, and Dynorphin Immunoreactivities in the Infundibular Nucleus of Young Male Human Subjects Challenges the KNDy Neuron Concept. [PDF]

, 2012
Previous immunohistochemical and in situ hybridization studies of sheep, goats, and rodents indicated that kisspeptin (KP), neurokinin B (NKB), and dynorphin A (DYN) are extensively colocalized in the hypothalamic arcuate nucleus, thus providing a basis ...

The role of the dynorphin/κ opioid receptor system in anxiety

Acta Pharmacologica Sinica, 2015
Anxiety disorders are the most common and prevalent forms of psychiatric disease, although the biological basis of anxiety is not well understood. The dynorphin/κ opioid receptor system is widely distributed in the central nervous system and has been ...

Synergistic Effect of Combination Treatment of Brexpiprazole and Nalmefene on Ethanol Intake in Rats

Neuropsychopharmacology Reports, Volume 46, Issue 1, March 2026.
Combination effect of nalmefene and brexpiprazole on ethanol intake in rats. The combination of subeffective doses of nalmefene (0.04 mg/kg, s.c.) and brexpiprazole (0.01 mg/kg, p.o.) significantly and synergistically decreased the average ethanol intake for 4 days compared with before the treatment (interaction effect: p = 0.0033 by two‐way ANOVA ...
