This study shows that fNIRS-based neurofeedback can modulate rTPJ activity and affect attention reorienting, with learning differences between up- and downregulation groups.

The paper introduces an fMRI-based paradigm to assess semantic congruency effects on episodic memory in older multilingual individuals, finding robust neural differences between semantically related and unrelated stimuli.

The paper assesses whether longitudinal resting state EEG data can reliably distinguish neurophysiological changes from cognitive state confounding, finding that multi-frequency, multi-channel classifiers achieve high cross-day accuracy.
