Oscillatory interactions in local and large-scale cortical networks mediate perceptual decision-making. (A) Local gamma-band activity in visual (MT) and motor cortex (M1) reflects the encoding of sensory evidence and motor plan, respectively. Top-down processes modulate this local activity. (B) Large-scale beta-band activity in a network centered on prefrontal (dlPFC) and parietal cortex (IPS) is involved in mapping the sensory evidence onto motor plans. (C) Large-scale gamma-band synchrony in a network across prefrontal (FEF), parietal (FEF), and visual cortex (MT) mediates the attentional selection of task-relevant sensory evidence (M1, primary motor cortex; MT, middle temporal area; dlPFC, dorsolateral prefrontal cortex; IPS, intraparietal sulcus; FEF, frontal eye field).
