From: The enhanced information flow from visual cortex to frontal area facilitates SSVEP response: evidence from model-driven and data-driven causality analysis

Figure 3

The directed information flow differences among the four conditions revealed by PDC analysis.

(a) Statistical difference; (b) The corresponding information exchange between the visual cortex and frontal area. Visual cortex (VC) contains the four electrodes V1_L, V1_R, V2_L and V2_R; frontal area (FA) contains the two electrodes FrA_L and FrA_R. And VC to FA indicates the directed information exchange from visual cortex to frontal area, FA to VC indicates the directed information exchange from frontal area to visual cortex, Visual Cortex represents internal information flows of visual cortex, Frontal area represents the internal information flows of frontal area.
