AB Evidence accumulates to show that semantic cognition requires, in addition to semantic representations, controlprocesses that regulate the accessibility and use of semantic knowledge in a task- and time-appropriate fashion.Semantic control has been recently proposed to rely on a distributed network that includes the posterior temporalcortex. Along these lines, recent meta-analyses of neuroimaging data and studies with patients suffering fromsemantic aphasia have suggested that the left posterior middle temporal gyrus (pMTG) is critically involvedwhenever situational context must constrain semantic retrieval. In the present experiment, we used transcranialdirect current stimulation over the left posterior temporal lobe in an attempt to interfere with semantic controlwhile participants performed a DRM task, a procedure for inducing conceptually-based false recognition that iscontingent on both activation and control processes. Paralleling findings with patients suffering from braindamage restricted to the temporoparietal cortex, anodal stimulation (relative to sham stimulation) resulted inincreased false recognition but intact true recognition. These findings fit well with the idea that the left pMTG is akey component of a semantic control network, the alteration of which results in m
