Abstract
Commentary: The Role of the Parietal Cortex in the Representation of Task-Reward Associations.
Highlights
Linked to domains such as attention (Corbetta and Shulman, 2002), episodic memory (Cabeza et al, 2008) and language (Price, 2010), profiling of the heterogeneous inferior parietal cortex (IPC) is challenging
The information required for task execution gradually unfolded across a trial: Participants subsequently received a symbolic task-reward association cue (2-s) followed by a 6-s delay, a fully informative task cue (1.5-s) followed by a 1.5s delay, and the target stimulus followed by some time to respond1
During phase 1 the bilateral IPC coded for the instructed task-reward associations
Summary
Linked to domains such as attention (Corbetta and Shulman, 2002), episodic memory (Cabeza et al, 2008) and language (Price, 2010), profiling of the heterogeneous inferior parietal cortex (IPC) is challenging. Wisniewski and colleagues explored the brain areas underlying associations between tasks (parity/magnitude) and rewards (high/low). During phase 1 the bilateral IPC coded for the instructed task-reward associations.
