The dorsal and ventral streams include the occipital cortex and the posterior parietal cortex (PPC) and inferior temporal cortex (ITC), respectively. The dorsal frontoparietal network includes the PPC and the prefrontal cortex (PFC). The ventral frontoparietal network includes the inferior frontal gyrus (IFG) and the temporoparietal junction (TPJ). Motor attention includes the primary sensory cortex (S1) and the PPC. The PPC is important for the dorsal visual stream (part of visuospatial attention), the dorsal frontoparietal network, and motor attention.
The prefrontal cortex (PFC) selects a movement-related goal while sensory signals from the dorsal stream and primary sensory cortex (S1) converge on the posterior parietal cortex (PPC). The PPC narrows (or converges) the attentionally selected signals pertaining to the goal, based on visuospatial and motor attentional priorities. The supplementary motor area (SMA) and premotor cortex (PMc) areas receive this information and generate a motor plan based on the attention-filtered sensory signals and movement goals. The PPC is important for the dorsal visual stream (part of visuospatial attention), the dorsal frontoparietal network, and motor attention.
