How does the brain prioritise information that is important to our current goals? Using a combination of neuroimaging and neurostimulation techniques we asked whether the dorsolateral prefrontal cortex plays a role in the selection of relevant information and/or the inhibition of irrelevant information. The data presented provide causal evidence in support of major theories implicating that the primary mechanism for control by right dlPFC is in biasing processing towards information that is relevant to our behaviour.
