Motion perception getting better with age?

Neuron. 2005 Feb 3;45(3):325-7. doi: 10.1016/j.neuron.2005.01.017.

Abstract

Older people can discriminate visual motion of large, high-contrast stimuli better than young adults. This surprising result, reported by Betts et al. in this issue of Neuron, suggests weaker center-surround antagonism in senescence, perhaps attributable to age-related reduction in GABA-mediated inhibition.
