Aging is the biological process of declining physiologic function associated with increasing
mortality rate during advancing age. Humans and higher nonhuman primates exhibit …

In the mammalian brain, adult neurogenesis has been extensively studied in the
hippocampal sub-granular zone and the sub-ventricular zone of the anterolateral ventricles …

Circadian rhythms are ubiquitous attributes across living organisms and allow the
coordination of internal biological functions with optimal phases of the environment …

The physiological aging process is well known for functional decline in visual abilities.
Among the components of the visual system, the dorsal lateral geniculate nucleus (DLG) …

The human hair follicle (HF) exhibits peripheral clock activity, with knock-down of clock
genes (BMAL1 and PER1) prolonging active hair growth (anagen) and increasing …

The prevalence of cognitive impairments and circadian disturbances increases in the elderly
and Alzheimer's disease (AD) patients. This study investigated the effects of a standardized …

In mammals, the suprachiasmatic nucleus (SCN) is the location of a master circadian
pacemaker. It receives photic signals from the environment via the retinal hypothalamic tract …

In mammals, the suprachiasmatic nucleus (SCN) and the intergeniculate leaflet (IGL) are the
main components of the circadian timing system. The SCN, classically known as the master …

The normal aging process is accompanied by functional declines in image-forming and non-
image forming visual systems. Among the components of these systems, the thalamic lateral …

It is the heterogeneous changes of hypothalamic functions that determine the chronological
sequence of aging in mammals. Recently, it was hypothesized by Cai the decrease in slow …
