Parietal lobe abs. volume (left)

Parietal lobe problems cause bizarre symptoms that seem unrelated. Left parietal damage causes difficulty with calculations, left-right confusion, finger agnosia (not knowing which finger is which), and problems writing. Right parietal damage causes hemispatial neglect - ignoring the left side of space (eating only from right side of plate, shaving only right side of face), difficulty dressing, and denying illness exists. Both sides affect spatial navigation - getting lost in familiar places, inability to judge distances, and difficulty reaching for objects accurately.
