Neural Mechanisms of Transient and Sustained Cognitive Control during Task Switching Todd S Braver, Jeremy R Reynolds, David I Donaldson Neuron Volume 39, Issue 4, Pages 713-726 (August 2003) DOI: 10.1016/S0896-6273(03)00466-5

Figure 1 Task Design State effects are estimated by comparing the sustained element of the bold signal during the task block to the blocks of fixation trials, whereas item effects are estimated by comparing the event-related response to different trial types within each task block (task-repeat versus task-switch trials in the mixed block) or different trial types across blocks (task-repeat trials in the mixed block versus trials in the single-task block). In mixed-task blocks, task cues vary randomly from trial-to-trial, producing both task-switch and task-repeat trials. In single-task blocks (data not shown), the task cue stays the same throughout the block. Neuron 2003 39, 713-726DOI: (10.1016/S0896-6273(03)00466-5)

Figure 2 Transient and Sustained Brain Activity during Task Switching (A) All identified brain regions, imposed on an inflated surface rendering. Red regions were identified via the transient analysis, whereas yellow regions were identified via the sustained analysis. (Top) Anterior and lateral views of the left hemisphere. (Bottom) Lateral, anterior, and medial views of the right hemisphere. (B) All identified brain regions, projected onto cortical flat maps for each hemisphere. Both panels were created using CARET software (Van Essen et al., 2001). Neuron 2003 39, 713-726DOI: (10.1016/S0896-6273(03)00466-5)

Figure 3 Right Anterior Prefrontal Cortex Activity Region identified in the sustained analysis (center of mass: 34, 48, 18) and its corresponding effects. (A) Estimated state effects. Error bars correspond to the 95% C.I. around the difference between conditions. (B) Estimated time courses for task-repeat and task-switch trials in the mixed-task condition and trials in the single-task condition. (C) Estimated time courses for the fastest trials in each of the three conditions. (D) Estimated time courses for the slowest trials in each of the three conditions. Neuron 2003 39, 713-726DOI: (10.1016/S0896-6273(03)00466-5)

Figure 4 Left Lateral Prefrontal Cortex Activity Region identified in the transient analysis (center of mass: −46, 15, 21) and its corresponding effects. (A) Estimated state effects. Error bars correspond to the 95% C.I. around the difference between conditions. (B) Estimated time courses for task-repeat and task-switch trials in the mixed-task condition and trials in the single-task condition. (C) Estimated time courses for the fastest trials in each of the three conditions. (D) Estimated time courses for the slowest trials in each of the three conditions. Neuron 2003 39, 713-726DOI: (10.1016/S0896-6273(03)00466-5)

Figure 5 Left Superior Parietal Cortex Activity Region identified in the transient analysis (center of mass: −28, −66, 45) and its corresponding effects. (A) Estimated state effects. Error bars correspond to the 95% C.I. around the difference between conditions. (B) Estimated time courses for task-repeat and task-switch trials in the mixed-task condition and trials in the single-task condition. (C) Estimated time courses for the fastest trials in each of the three conditions. Notice the difference in estimated time courses between task-switch and task-repeat trials. (D) Estimated time courses for the slowest trials in each of the three conditions. Notice the identical nature of the estimated time courses between task-switch and task-repeat trials.
