Glaucoma is an age-related neurodegenerative disease of the visual system, affecting both
the eye and the brain. Yet its underlying metabolic mechanisms and neurobehavioral …

Previous studies have reported inconsistent effects of dietary restriction (DR) on cortical
inhibition. To clarify this issue, we examined the response properties of neurons in the …

The role of age in perception and production of facial expressions is still unclear. Therefore,
this work compared, in aged and young subjects, the effects of passive viewing of faces …

Psychophysical studies on human and non-human vertebrate species have shown that
visual contrast sensitivity function (CSF) peaks at a certain stimulus spatial frequency and …

ABSTRACT GABA is the principal inhibitory neurotransmitter in the human brain and can be
measured with Magnetic Resonance Spectroscopy (MRS). Conflicting accounts report …

Recent research had shown a correlation between aging and decreasing Gamma‐
aminobutyric acid (GABA), the primary inhibitory neurotransmitter in the brain. However, how …

Epigenetic mechanisms of gene regulation as the interface between the genome and
environment, control diverse processes in development, aging and disease. As proposed by …

We aimed to determine the value of the paired‐pulse inhibition (PPI) in the auditory cortex in
patients with Parkinson′ s disease (PD) and analyze its dependence on clinical …

Human visual function degrades with age. Previous studies of visual perception have shown
that aged people have worse performance in the coding of orientation information. However …

We see the world with two eyes. Binocular vision provides more ample information through
interocular interaction. Previous studies have shown that aging impairs a variety of visual …
