Voluntary and Involuntary auditory attention after lesion of the dorsolateral prefrontal cortex: an EEG study in Humans

Description

An efficient control of attention relies on a good balance between two important facets of attention: voluntary attention which enables to focus on relevant information for a given purpose, and involuntary attentional capture by events, outside the attentional focus, irrelevant to the task in hand, but potentially important (e.g. a fire alarm). These two types of attention rely on partially separated networks. Voluntary attention would be supported by the dorsal attention network including the intraparietal sulcus and the frontal eye fields. Involuntary attention would be supported by the ventral attention network including the temporo-parietal junction and the ventral frontal cortex. The two networks mainly overlap in the dorsolateral prefrontal cortex (dlPFC).
Lesions of the dlPFC have been shown to alter both voluntary and involuntary attention in distinct studies. However, the impact of such lesions on the balance between voluntary and involuntary attention still need to be explored.
