Long-range synchronization of oscillatory light responses in the cat retina and lateral geniculate nucleus

Article Abstract:

Structured light stimuli activate synchronized retinal ganglion cell oscillatory responses in frequency range of 61-114 Hz. The distances are greater than 20 degrees of visual angle across the nasal and temporal halves of the retina. Multi-electrode recordings from lateral geniculate nucleus (LGN) and retina indicate that LGN neurons transmit temporal pattering of response to evoke synchronous response. The phase-locking of spatially adjacent oscillatory modules traversing horizontally across the retina generate synchronization.

Visuomotor integration is associated with zero time-lag synchronization among cortical areas

Article Abstract:

Neuronal response synchronization occurs within various cortical regions. Studies show that coupling strength among the visual, sensorimotor and pre-frontal cortex regions changes during task performance. The areas also exhibit strong synchronization activity with close to zero time lag during attentive processing. Synchrony between areas in various hemispheres were also found to rely on the cortico-cortical connections' integrity.

Neural synchrony correlates with surface segregation rules

Article Abstract:

Neurons in the visual cortical areas A18 and PMLS synchronize their discharges when responding to contours of the same surface but not when responding to contours belonging to different surfaces. Dynamic changes in synchronization could encode links between simultaneous responses to spatially superimposed contours.
