Traveling Waves in Visual Cortex

Long-range traveling waves of activity triggered by local dichoptic stimulation in V1 of behaving monkeys.

Traveling waves of cortical activity, in which local stimulation triggers lateral spread of activity to distal locations, have been hypothesized to play an important role in cortical function. However, there is conflicting physiological evidence for the existence of spreading traveling waves of neural activity triggered locally. Dichoptic stimulation, in which the two eyes view dissimilar monoc...

Robustness of traveling waves in ongoing activity of visual cortex.

Numerous studies have revealed traveling waves of activity in sensory cortex, both following sensory stimulation and during ongoing activity. We contributed to this body of work by measuring the spike-triggered average of the local field potential (stLFP) at multiple concurrent locations (Nauhaus et al., 2009) in the visual cortex of anesthetized cats and macaques. We found the stLFP to be prog...

Title : Long - range traveling waves of activity triggered by 1 local dichoptic stimulation in V 1 of behaving monkeys

25 Traveling waves of cortical activity, in which local stimulation triggers lateral spread of activity to 26 distal locations, have been hypothesized to play an important role in cortical function. However, 27 there is conflicting physiological evidence for the existence of spreading traveling waves of 28 neural activity triggered locally. Dichoptic stimulation, in which the two eyes view diss...

Callosal Connections of Primary Visual Cortex Predict the Spatial Spreading of Binocular Rivalry Across the Visual Hemifields

In binocular rivalry, presentation of different images to the separate eyes leads to conscious perception alternating between the two possible interpretations every few seconds. During perceptual transitions, a stimulus emerging into dominance can spread in a wave-like manner across the visual field. These traveling waves of rivalry dominance have been successfully related to the cortical magni...
