TY - JOUR T1 - A causal role for right frontopolar cortex in directed, but not random, exploration JF - bioRxiv DO - 10.1101/064741 SP - 064741 AU - Wojciech Zajkowski AU - Malgorzata Kossut AU - Robert C. Wilson Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/07/19/064741.abstract N2 - The explore-exploit dilemma occurs anytime we must choose between exploring unknown options for information and exploiting known resources for reward. Previous work suggests that people use two different strategies to solve the explore-exploit dilemma: directed exploration driven by information seeking and random exploration driven by decision noise. Here, we show that these two strategies rely on different neural systems. Using transcranial magnetic stimulation to selectively inhibit right frontopolar cortex, we were able to selectively inhibit directed exploration while leaving random exploration intact, suggesting a causal role for right frontopolar cortex in directed, but not random, exploration.
