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.

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.

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 ...

Modulating effect of irisin on the functional state of inhibitory afferent inputs to the suprachiasmatic nucleus from the arcuate nucleus [PDF]

BIO Web of Conferences
In vitro experiments on viable hypothalamic slices of male Wistar rats, the modulating effect of the myokine irisin on the parameters of inhibitory responses of neurons in the suprachiasmatic nucleus to stimulation of the arcuate nucleus was studied.

Circadian rhythm mechanism in the suprachiasmatic nucleus and its relation to the olfactory system

Frontiers in Neural Circuits
Animals need sleep, and the suprachiasmatic nucleus, the center of the circadian rhythm, plays an important role in determining the timing of sleep. The main input to the suprachiasmatic nucleus is the retinohypothalamic tract, with additional inputs ...

The Hypothalamus of the Beaked Whales: The Paraventricular, Supraoptic, and Suprachiasmatic Nuclei

Biology, 2023
The hypothalamus is the body’s control coordinating center. It is responsible for maintaining the body’s homeostasis by directly influencing the autonomic nervous system or managing hormones. Beaked whales are the longest divers among cetaceans and their

Stereotaxic Surgery for Suprachiasmatic Nucleus Lesions in Mice

Bio-Protocol, 2017
Site-specific lesions are invaluable methods for investigating the function of brain regions within the central nervous system and can be used to study neural mechanisms of behaviors. Precise stereotaxic surgery is required to lesion small regions of the

S20098 Affects the Free-Running Rhythms of Body Temperature and Activity and Decreases Light-Induced Phase Delays of Circadian Rhythms of the Rat [PDF]

, 2001
Mammalian endogenous circadian rhythms are entrained to the environmental day-night cycle by light exposure. Melatonin is involved in this entrainment by signaling the day-night information to the endogenous circadian pacemaker. Furthermore, melatonin is
