The neural coding of value information is critical to the decision process, guiding the choice between potential options and bridging the gap between sensation and action. We have recently shown that value coding in parietal cortex is relative rather than absolute, imparting an intrinsic context-dependence to value representation. Action value coding in sensorimotor circuits like parietal cortex likely also involve a rich network of interrelated brain areas, such as frontal and striatal regions; we aim to examine these interactions via multisite and multilayer recordings.
