Brain glucose feedback predicts food choice (Commentary on Wakabayashi et al.)

Abstract

Strategies for making choices are of broad multidisciplinary interest (Glimcher, 2010). From a viewpoint of evolutionary survival, speed and accuracy are desirable, but contradictory, attributes of decision-making. Indeed, observations in many fields, including neuroscience, economics, and psychology, suggest that choice involves trade-off between accuracy and speed (e.g. Abraham et al., 2004; Kahneman, 2011). A much-discussed theory is that the brain has evolved one system for using indirect but easily accessible information to make rapid but potentially inaccurate decisions, and another system for using direct but harder-to-get information to make more accurate but slower decisions (Kahneman, 2011).
