Both parietal and frontal lobe play roles in directing conscious attention. The frontal lobes have a role in assessing competing stimuli, and the parietal lobes are needed in order to attend to them. I suspect that more abstract topics for contemplation also compete for attention by the more serially behaving conscious. The exact mechanisms aren't clear to me at this time.
