Increased activity in the PLs often indicates hypersensitivity to noise, touch and taste.   The parietal lobes have also been implicated in attentional issues and distractibility (too much stimulation comes in).   In addition, when there is both sided parietal lobe and frontal lobe activity it is often associated with a pattern we call the ring of fire.   Decreased activity in the PLs may be associated with trauma, toxicity, or memory loss.
