Journal of Circadian Rhythms, 2015 The mammalian circadian clock is composed of single-cell oscillators. Neurochemical and electrical signaling among these oscillators is important for the normal expression of circadian rhythms.

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.Sturgeons are an ancient and basal group of ray‐finned fishes whose pallium consists of lateral, medial, and posterior divisions. The connections of these divisions were determined by injections of biotinylated dextran amine and DiI. Although there is considerable overlap in the connections of these pallial divisions, their heaviest connections are ...

Calretinin Neurons in the Rat Suprachiasmatic Nucleus [PDF]
Journal of Biological Rhythms, 2016 The hypothalamic suprachiasmatic nucleus (SCN), a circadian pacemaker, is present in all mammalian brains. It has a complex organization of peptide-containing neurons that is similar among species, but calcium-binding proteins are expressed variably.

Molecular Ontology Predicts Output Connections From the Nucleus of the Solitary Tract
Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.The nucleus of the solitary tract (NTS) integrates visceral inputs to coordinate appetite and digestion, breathing, and cardiorespiratory reflexes. Using cell‐type‐specific tracing, we show that excitatory Lmx1b neurons project broadly to brainstem and forebrain targets, whereas inhibitory output remains largely brainstem‐restricted. Catecholaminergic (

Loss of dopamine disrupts circadian rhythms in a mouse model of Parkinson's disease
Neurobiology of Disease, 2014 Although a wide range of physiological functions regulated by dopamine (DA) display circadian variations, the role of DA in the generation and/or modulation of these rhythms is unknown.

Brain‐Wide Mapping and Synaptic Localization of C1QL3 Using a Novel Epitope‐Tagged Knock‐In Mouse
Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.C1QL3 is a secreted adhesion molecule that acts as a key regulator of synaptic structure and function. We generated and validated a novel epitope‐tagged knock‐in mouse line (C1ql32HA) in which two hemagglutinin (HA) epitopes were inserted near the N‐terminus of the endogenous C1QL3 protein.

CIRCADIAN RHYTMICITY AND DEPRESSION
Zdravniški Vestnik, 2008 BACKGROUND Depression is the most common psychiatric syndrome treated on the primary level. Abnormal patterns of circadian rhythms are associated with a large variety of affective disorders including depression.

Molecular Nutrition &Food Research, Volume 70, Issue 15, 17 August 2026.Male BALB/c mice were assigned to control, circadian disruption, or circadian disruption plus probiotic groups for 16 weeks. Body weight and circadian clock gene expression (Clock, Bmal1, and Per2) were evaluated. Probiotic supplementation partially modulated weight gain and influenced circadian gene regulation, supporting its potential as an adjunct ...

Nature Communications, 2019 The suprachiasmatic nucleus (SCN) synchronises daily rhythms of behaviour and physiology to the light-dark cycle. Vasoactive intestinal peptide (VIP) is important for mediating SCN entrainment; however, the underlying mechanisms are incompletely ...

Circadian clock network desynchrony promotes weight gain and alters glucose homeostasis in mice
Molecular Metabolism, 2019 Objective: A network of endogenous circadian clocks adapts physiology and behavior to recurring changes in environmental demands across the 24-hour day cycle. Circadian disruption promotes weight gain and type 2 diabetes development.
