It is well established that many visual functions deteriorate with age. Perhaps counter-
intuitively, a recent study revealed that older people actually require less time to discriminate …

One of the biggest questions in learning is how a system can resolve the plasticity and
stability dilemma [1–3]. Specifically, the learning system needs to have not only a high …

People often experience age-related declines in cone-based visual capacities despite an
absence of apparent visual pathology. Although mice are used as models of human visual …

In addition to motion perception per se, we utilize motion information for a wide range of
brain functions. These varied functions place different demands on the visual system, and …

Intuitively one might think that larger objects should be easier to see, and indeed
performance on visual tasks generally improves with increasing stimulus size [1, 2] …

Perceptual analogues of centre–surround suppression have been applied as indirect
measures of cortical inhibitory function in several clinical disorders. Two tasks have been …

Three experiments investigated whether and to what extent increases in age affect the
functionality of stereopsis. The observers' ages ranged from 18 to 83 years. The overall goal …

Psychophysical surround suppression is believed to reflect inhibitory neuronal mechanisms
in visual cortex. In recent years, two psychophysical measures of surround suppression …

Purpose: Center-surround contrast suppression—typically induced when a center pattern is
surrounded by another pattern with similar spatial features—is considered a perceptual …

Individuals with depression show depleted concentrations of the inhibitory neurotransmitter
GABA in occipital (visual) cortex, predicting weakened inhibition within their visual systems …
