Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

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

Entropy, 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 ...

From regulatory mechanisms to cutting‐edge applications: Research progress of ultrasound, electrical, magnetic, and optical stimulation in neural modulation

Journal of Intelligent Medicine, EarlyView.
Abstract In recent years, the clinical treatment and symptom management of neurological disorders have faced significant challenges due to the high complexity of the nervous system's structure and function. Against this backdrop, physical stimulation techniques have emerged as a vital complementary approach to traditional pharmacological treatments and

Attention‐Deficit/Hyperactivity Disorder Through a Circadian Lens: When the Brain's Clock Disrupts Attention Regulation

Medicine Bulletin, EarlyView.
ABSTRACT Attention‐deficit/hyperactivity disorder (ADHD) is increasingly linked to disturbances in circadian regulation, yet this temporal dimension remains insufficiently integrated into research and clinical practice. This perspective synthesises current evidence on circadian misalignment in ADHD, reframing commonly reported sleep disturbances and ...

Photic Stimulation Study of Changing the Arterial Partial Pressure Level of Carbon Dioxide

, 1995
To investigate the effect of the level of baseline cerebral blood flow (CBF) on local CBF augmentation by activation, we have used positron emission tomography to measure regional CBF (rCBF) in 12 normal volunteers with and without photic stimulation ...

Pattern-Sensitive Epilepsy

Pediatric 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.

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

Journal 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.

Photic stimulation inhibits growth hormone secretion in rats: A hypothalamic mechanism for transient entrainment

, 2004
It is well established that photic cues are used by the suprachiasmatic nucleus (SCN) to entrain circadian rhythms to the light/dark cycle, but the role of photic stimuli in the regulation of ultradian neuroendocrine rhythms is ill defined.

Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...
