Spatial and temporal sensitivity degradation of primary visual cortical cells in senescent rhesus monkeys

J Zhang, X Wang, Y Wang, Y Fu, Z Liang… - European Journal of …, 2008 - Wiley Online Library

central visual pathways. In this study we compared the spatial and temporal sensitivities of …

Functional degradation of visual cortical cells in aged rats

H Wang, X Xie, X Li, B Chen, Y Zhou - Brain research, 2006 - Elsevier
Functional degradation of mammalian visual cortex is associated with aging. It has been

Aging affects response variability of V1 and MT neurons in rhesus monkeys

Y Yang, Z Liang, G Li, Y Wang, Y Zhou - Brain research, 2009 - Elsevier
Visual function declines with age. Much of the decline may result from functional
degradation in central visual areas. To investigate the physiological mechanisms underlying …

Functional degradation of extrastriate visual cortex in senescent rhesus monkeys

S Yu, Y Wang, X Li, Y Zhou, AG Leventhal - Neuroscience, 2006 - Elsevier
The receptive field properties of striate cortical (V1) cells degrade in senescent macaque

Degradation of signal timing in cortical areas V1 and V2 of senescent monkeys

Y Wang, Y Zhou, Y Ma, AG Leventhal - Cerebral Cortex, 2005 - academic.oup.com
Senescence in monkeys results in a degradation of the functional properties of cortical cells
as well as prolonged hyperactivity. We have now compared the spontaneous and visually …

[HTML][HTML] The effects of aging on orientation discrimination

LR Betts, AB Sekuler, PJ Bennett - Vision research, 2007 - Elsevier
The current experiments measured orientation discrimination thresholds in younger (mean
