Schematic mechanism of attention’s modulation of SPC. This scheme shows how attention may determine the low-frequency synchrony between neurons, via modulating their coupling to an intra-regional subnetwork that generates low-frequency activity (potentially consisted of O-LM inter-neurons). This subnetwork’s local connection to the principal cells might be regulated by the feedback as well as neuromodulatory projections that are carrying the attention signal to the visual cortex (here, MT)
