Dissociating Semantic Integration and Inhibitory Control in the Remote Associates Test: A tDCS-EEG Study Lezama, Raquel Gómez Ariza, Carlos Javier Bajo Molina, María Teresa semantic memory inhibitory control EEG neuromodulation tDCS creativity creative problem-solving The work reported here was supported by the Spanish Ministry of Universities (Grant FPU019/02694) to RL, by grants from the Spanish Ministry of Science and Innovation PGC2018-093786-B-I00 to MTB and PID2021-122979OB-C21 to CJGA, and PID2021-127728NB-I00 to MTB. Neuromodulation was utilized here to investigate the distinct involvement of two recognized cortical hubs for semantic integration (the left anterior temporal lobe, lATL) and inhibitory control (the right dorsolateral prefrontal cortex, rDLPFC) in creative problem-solving. Participants were presented with a list of category-exemplar words, selectively recalled some of them, and then solved a set of RAT problems. Selective retrieval was introduced to trigger inhibitory control over competitors. Critically, some RAT problems could be solved with words from the previous phases of the experiment, including words that might be less accessible due to inhibition. Other problems, however, could only be solved with unpresented words. Experiment 1 showed that anodal tDCS over the lATL had a negative effect on the production of correct responses to baseline RAT problems, but not on those that required inhibited solutions. Experiment 2 produced the reverse pattern with cathodal tDCS over the rDLPFC. Resting-state EEG recordings were obtained before and after delivering tDCS, which also revealed specific tDCS-induced changes in frequency bands depending on the site of stimulation. Overall, these findings provide support for the involvement of semantic and control processes in creative problem solving that are linked to different brain networks. 2024-10-09T10:56:55Z 2024-10-09T10:56:55Z 2024-06-06 journal article Published version: Lezama, R., Gómez-Ariza, C.
