Long-range Interactions in Primary Visual Cortex

Two different natural movies and derived local stimulation conditions are shown as they were used during one of the experiments. To facilitate inspection, movies are shown at half of the speed (12 Hz) used during the experiments. The right-hand color labels (red/blue) code for condition identity. The monitor covered a visual field of approximately 30×40 degrees. - See more at: http://f1000research.com/articles/2-51/v2#sthash.0qbKLqgb.dpuf

Two natural movies were presented locally -

cortical responses are depicted below.

Note the high spatio-temporal coherence in activity when both spots were presented simultaneously, indicating cooperative long-range interactions.



Movies are shown at half of their original speed (12 Hz). The monitor covered a visual field of 30x40 deg (see full-screen movies at left).
