Ablation of microglia does not alter circadian rhythm of locomotor activity

Molecular Brain, 2023
Microglia, as macrophages in the brain, are responsible for immune responses and synaptic remodeling. Although the function of microglia is regulated by circadian rhythms, it is still unclear whether microglia are involved in the generation and light ...

The presence of neuronal-specific nuclear protein (NeuN) in the circadian timing system of the capuchin monkey (Cebus apella)

Sleep Science, 2010
Background and objective: The circadian timing system (CTS) is composed of a group of specialized neuronal structures that establish a temporal organization of physiological and behavioral processes within precise patterns.

Effects of ionophoretically applied bombesin-like peptides on hamster suprachiasmatic nucleus neurons in vitro

, 1994
Ionophoresis of the smaller bombesin-like peptides (gastrin releasing peptide [GRP]-(18-27), neuromedin B, and bombesin) evoked responses from 30-60% of hamster suprachiasmatic nucleus cells recorded in a hypothalamic slice preparation, depending on the ...

Circadian rhythm of PERIOD2::LUCIFERASE expression in the trigeminal ganglion of mice

Frontiers in Neuroscience, 2023
IntroductionThe trigeminal nerve conveys delicate sensations such as warmth, pain, and tactile pressure in the oral and facial regions, and most trigeminal afferent cell bodies are located in the trigeminal ganglion.

Paradoxical Sleep Suppresses Immediate Early Gene Expression in the Rodent Suprachiasmatic Nuclei

Frontiers in Neurology, 2010
Light stimulates neuronal activity with subsequent expression of the protein product of the immediate early gene, c-fos, in the Suprachiasmatic Nuclei (SCN). Non-photic stimuli is also thought to modulate activity within the SCN.

In-phasic cytosolic-nuclear Ca2+ rhythms in suprachiasmatic nucleus neurons

Frontiers in Neuroscience, 2023
The suprachiasmatic nucleus (SCN) of the hypothalamus is the master circadian clock in mammals. SCN neurons exhibit circadian Ca2+ rhythms in the cytosol, which is thought to act as a messenger linking the transcriptional/translational feedback loop ...

The Suprachiasmatic Nucleus Regulates Anxiety-Like Behavior in Mice

Frontiers in Neuroscience, 2022
Individuals suffering from mood and anxiety disorders often show significant disturbances in sleep and circadian rhythms. Animal studies indicate that circadian rhythm disruption can cause increased depressive- and anxiety-like behavior, but the ...

Mathematical model of the interaction between the dorsal and ventral regions of the suprachiasmatic nucleus of rats

Sleep Science, 2010
Background and objective: In mammals, the main biological clock that is synchronized by light is located in the suprachiasmatic nucleus of the hypothalamus, which can be divided into two distinct regions: the ventrolateral and the ...
