A single session of HF-rTMS over the left DLPFC selectively altered the neural dynamics of episodic memory retrieval for abstract portrait stimuli. Although behavioral performance did not improve-and showed reduced accuracy for previously seen items-stimulation elicited increased activation in hippocampal subregions and early visual cortex during successful retrieval. These findings demonstrate that prefrontal neuromodulation can reshape hippocampal-visual network engagement during episodic reca
