abstract = {As we move through an environment, the positions of
surrounding objects relative to our body constantly change,
with some objects even leaving our field of view. As a
consequence, maintaining orientation requires spatial
updating, the continuous monitoring of self-motion cues to
update external locations within an egocentric frame of
reference. While previous research using functional magnetic
resonance imaging has implicated the precuneus in spatial
updating, direct evidence for this claim is missing. To
address this important question, we applied theta burst
repetitive transcranial magnetic stimulation (rTMS) over the
precuneus to induce a 'virtual lesion'. Following
stimulation, participants were tested in a large-scale
virtual environment in which they had to use visual
self-motion information to keep track of the position of
virtual objects. Compared to sham stimulation, rTMS affected
working memory traces for object locations. Critically, rTMS
further impaired the ability to update these locations
whenever participants experienced simulated movement. As
this effect could not be explained by working memory
deficits alone, we conclude that visual spatial updating
relies on the construction of updated representations of
egocentric object locations within the precuneus. Together,
these findings establish the precuneus as performing key
computations for the formation of cognitive maps.},
