A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Synchronization‐Dissipation in the Cardiorespiratory System
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Circadian rhythms and diabetes [PDF]
All free‐living organisms are regulated by the 24‐h light and dark cycle produced by Earth’s rotation. In mammals, circadian rhythms are indispensble for the regulation of physiological and biochemical processes in the body. In 1972, the suprachiasmatic nucleus was shown to be required for daily rhythms in animal behavior1.

Schematic illustration of development of experimental datasets and algorithm models, screening and preparation of the scaffolds and their applications in vivo. ABSTRACT Bone defects require materials with osteogenic, neurogenic, and angiogenic activity, yet designing such materials within high‐dimensional compositional spaces remains challenging. Here,

Circadian rhythm perturbation causes IBS-like characteristics and altered fecal metabolome in mice
Background Circadian rhythm disturbance is associated with functional gastrointestinal disorders such as irritable bowel syndrome (IBS). This study aimed to explore the effects of dysregulated circadian rhythm on visceral sensitivity, colonic ...

Current role and future perspectives of electroacupuncture in circadian rhythm regulation
In recent years, in-depth research on chronobiology has been conducted, and the circadian rhythm has become a new target for the treatment of diseases. Circadian rhythms are closely related to the normal physiological functions of organisms.

Aging and circadian rhythms [PDF]
Circadian clocks are cell-autonomous molecular feedback loops that generate daily rhythms in gene expression, cellular functions, physiological processes and behavior. The mechanisms of circadian clocks are well understood in young fruit flies Drosophila melanogaster, but less is known about how circadian system changes during organismal aging. Similar

The hormonal Zeitgeber melatonin: role as a circadian modulator in memory processing [PDF]
The neuroendocrine substance melatonin is a hormone synthesized rhythmically by the pineal gland under the influence of the circadian system and alternating light/dark cycles. Melatonin has been shown to have broad applications, and consequently becoming
