Symbolic Entropy of the Amplitude rather than the Instantaneous Frequency of EEG Varies in Dementia

open access: yesEntropy, 2015
The dynamics of human electroencephalography (EEG) have been proved to be related to cognitive activities. This study separately assessed the two EEG components, amplitude and rhythm, aiming to capture their individual contributions to cognitive ...

The Melanocortin-4 Receptor Integrates Circadian Light Cues and Metabolism [PDF]

open access: yes, 2015
The melanocortin system directs diverse physiological functions from coat color to body weight homoeostasis. A commonality among melanocortin-mediated processes is that many animals modulate similar processes on a circannual basis in response to longer ...

Red‐light flashing pens and seizures in children

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Guidelines exist to limit seizure‐provoking visual stimuli. However, existing recommendations are not universally applied, and poorly regulated flickering lights are easily encountered in consumer products. Two girls experienced prolonged absence seizures triggered by a red‐light flickering pen.

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Pattern-Sensitive Epilepsy

open access: yesPediatric Neurology Briefs, 2005
The clinical and electroencephalographic (EEG) findings of 73 (43 female and 30 male) patients diagnosed with pattern-sensitive epilepsy between 1950 and 1999 were evaluated at the Mayo Clinic, Rochester, MN.

NAD+‒circadian rhythm coupling in dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Mouse circadian plasma leptin and active ghrelin rhythms under ad libitum and scheduled feeding [PDF]

open access: yes, 2007
Thesis (M.S.) University of Alaska Fairbanks, 2007Light is the strongest timing cue for the circadian system, but non-photic cues can also entrain the master circadian clock, i.e., suprachiasmatic nuclei (SCN).

Identification of novel light-induced genes in the suprachiasmatic nucleus [PDF]

open access: yes, 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.

PMS, EEG, and Photic Stimulation

open access: yesJournal of Neurotherapy, 1997
Abstract Two studies of premenstrual syndrome (PMS), EEG, and photic stimulation have recently been completed at the Royal Postgraduate Medical School, Hammersmith Hospital, London (UK). In a preliminary trial of photic stimulation as a treatment for PMS, seventeen women with PMS were treated with a take-home flashing light device for 15 to 20 minutes ...
