Analyses of neural activities at the end of the secondary task showed another important facet of interference effects check details in the LPFC. Watanabe and Funahashi [33••] found a significant ‘reawakening’ of neural encoding for
the visual cue location in the memory task after the end of the attention task (Figure 3e), which indicates that even under the presence of the interference effect caused by the attention task, some neural mechanisms in the LPFC could operate to compensate for the interference effect produced by the attention task. Similar results have been reported by Miyazaki et al. [32], who compared the activities of LPFC neurons and dorsal premotor neurons while monkeys performed a dual task, which consisted of memory-guided bimanual actions (primary task) and visually-guided bimanual actions (secondary task). The observed post-interference reactivation of the primary-task information showed that the LPFC played an important
role in exerting compensatory control over the interference by the secondary task. Flexible prioritization among multiple streams of concurrent task processing is critical for the coordination of dual-task performance. The observed reactivation may correspond to the neural implementation of adaptive task coordination see more in the LPFC 22 and 24. Behavioral analyses and physiological investigations of dual-task interference using monkeys are beginning to provide evidence regarding the neural mechanisms for interference control. The similarity of the behavioral patterns caused by dual-task interference in humans and monkeys and the capability GNA12 to elucidate the fine details of neural computations by neurophysiological methods support the view that the primate model
is an appropriate method for understanding the details of the neural mechanisms of the interference control and the flexible allocation of cognitive recourse. Nothing declared.
