Visual response latencies of magnocellular and parvocellular LGN neurons in macaque monkeys.
Signals relayed through the magnocellular layers of the LGN travel on axons with faster conduction speeds than those relayed through the parvocellular layers. As a result, magnocellular signals mightExpand

Physiological correlates of perceptual learning in monkey V1 and V2.
Performance in visual discrimination tasks improves with practice. Although the psychophysical parameters of these improvements have suggested the involvement of early areas in visual cortex, thereExpand

Functional Micro-Organization of Primary Visual Cortex: Receptive Field Analysis of Nearby Neurons
It is well established that multiple stimulus dimensions (e.g., orientation and spatial frequency) are mapped onto the surface of striate cortex. However, the detailed organization of neurons withinExpand

Receptive fields in human visual cortex mapped with surface electrodes.
Most of our understanding of the functional organization of human visual cortex comes from lesion and functional imaging studies and by extrapolation from results obtained by neuroanatomical andExpand

Attentional modulation in visual cortex depends on task timing
Paying attention to a stimulus selectively increases the ability to process it. For example, when subjects attend to a specific region of a visual scene, their sensitivity to changes at that locationExpand

Oscillatory discharge in the visual system: does it have a functional role?
1. The discharge of individual neurons in the visual cortex and lateral geniculate nucleus (LGN) of anesthetized and paralyzed cats and kittens was examined for the presence of oscillatory activity.Expand

Spatial Summation Can Explain the Attentional Modulation of Neuronal Responses to Multiple Stimuli in Area V4
Although many studies have shown that the activity of individual neurons in a variety of visual areas is modulated by attention, a fundamental question remains unresolved: can attention alter theExpand
