Epilepsia, EarlyView.Abstract Recurrent seizures, the hallmark of epilepsy, are influenced by rhythms operating over multiple timescales. Chronobiology is the study of biological timing that aims to explain temporal patterns of events like seizures. Fueled by recent advances in genetics, computational modeling, and device engineering, the chronobiology of epilepsy is now a

Identification of novel light-induced genes in the suprachiasmatic nucleus
BMC Neuroscience, 2007 Background The transmission of information about the photic environment to the circadian clock involves a complex array of neurotransmitters, receptors, and second messenger systems.

Neurobiology of Sleep and Circadian Rhythms, 2023 In mammals, photic information delivered to the suprachiasmatic nucleus (SCN) via the retinohypothalamic tract (RHT) plays a crucial role in synchronizing the master circadian clock located in the SCN to the solar cycle.

Clock gene dysregulation in epilepsy: A systematic review
Epilepsia Open, EarlyView.Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.

Imaging Individual Differences in the Response of the Human Suprachiasmatic Area to Light
Frontiers in Neurology, 2018 Circadian disruption is associated with poor health outcomes, including sleep and mood disorders. The suprachiasmatic nucleus (SCN) of the anterior hypothalamus acts as the master biological clock in mammals, regulating circadian rhythms throughout the ...

Circadian disruption and cancer- and treatment-related symptoms
Frontiers in Oncology, 2022 Cancer patients experience a number of co-occurring side- and late-effects due to cancer and its treatment including fatigue, sleep difficulties, depressive symptoms, and cognitive impairment.

Melanopsin-expressing retinal ganglion cells are resistant to cell injury, but not always [PDF]
, 2017 Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs deputed to non-image forming functions of the eye such as synchronization of circadian rhythms to light-dark cycle.
