Older adults consistently show slower reaction times (RTs) to the onset of motion. Both
cognitive slowing and motor slowing have been suggested as causes of this effect. The …

Visual function declines with age. Much of the decline may result from functional
degradation in central visual areas. To investigate the physiological mechanisms underlying …

Gamma oscillations are generated in networks of inhibitory fast-spiking (FS) parvalbumin-
positive (PV) interneurons and pyramidal cells. In animals, gamma frequency is modulated …

Human visual function declines with age. Much of this decline is mediated by changes in the
central visual pathways. In this study we compared the spatial and temporal sensitivities of …

Surround suppression was initially identified as a phenomenon at the neural level in which
stimuli outside the neuron's receptive field alone cannot activate responses but can …

The decline in visual function due to normal aging impacts various aspects of our daily lives.
Previous reports suggest that the aging retina exhibits mislocalization of photoreceptor …

Age-related declines in vision are well documented in the literature. In the present study we
examined whether changes in spatial or temporal integration contribute to this decline …

This study compared the effects of age on the perception of translational, radial, and
rotational global motion patterns. Motion coherence thresholds were measured for judging …

Perception of global patterns requires the integration of local orientation information across
space. The present study examined whether this integration ability declines in older age. We …

Human perception of speed declines with age. Much of the decline is probably mediated by
changes in the middle temporal (MT) area, an extrastriate area whose neural activity is …
