"Decision making in human parietal cortex."
Hide abstract
Many decisions faced by humans are inherently uncertain or ambiguous, where no one option is clearly better than another, such as when a pitcher chooses the type of pitch to throw in a baseball game. How do humans make decisions in the face of such uncertainty? This research focuses on the role of the inferior parietal cortex in decision making. It dissociates decision-making from general attention, and distinguishes different types of decision ambiguities. We conclude that the right inferior parietal lobule is specifically involved in decision making under uncertainty, rather than in any attention-demanding tasks or in any decision-making involving ambiguity.
