“…This may also be due to the difficult predictability of tDCS-induced current propagation in an anisotropic environment (Datta et al, 2009). Perhaps our results can add evidence to the arguments that P2 consists of subcomponents (García-Larrea et al, 1992; Silva et al, 2020). Whether this is correct, and whether we affected an early subcomponent of P2, which is the source of the observed plastic changes, remains to be studied in the future experiment, using the multichannel tDCS.…”

The effects of transcranial direct current stimulation (tDCS) on cognitive function are not always predictable based on the direction of the current and therefore remain widely debated. Contrary to the optimism of studies using transcranial electrical stimulation (tES) over the motor cortex, cognitive domain research demonstrates great ambiguity and diversity of stimulation-related effects. Here, we investigated such a controversial impact of tDCS over the posterior medial prefrontal cortex in a monetary incentive delay (MID) task with which one can study reward-based learning or reward processing a. We found that in tMID) task where subject anticipated small or big losses in different monetary contexts, cathodal stimulation suppressed plastic changes in sensory auditory P2 event-related potential and increased feedback-related negativity (FRN) implicated in reward-prediction error processing thus revealing multidirectional effect of tDCS in the same subject group performing the same experimental task. Our finding of multidirectionality of tDCS compromise the use of tES as a ready-to-use method to test brain causality in the neurocognitive events of high complexity such as decision-making.

“…There is also significant variability in the acquisition of auditory categories (e.g., Howard et al, 1992 ; Golestani and Zatorre, 2009 ; Mankel et al, 2020b ; Silva et al, 2020 ), especially for speech ( Wong et al, 2007 ; Díaz et al, 2008 ; Mankel et al, 2020a ; Fuhrmeister and Myers, 2021 ; Kajiura et al, 2021 ). More successful learners show greater neural activation, particularly in auditory cortex ( Wong et al, 2007 ; Díaz et al, 2008 ; Kajiura et al, 2021 ).…”

Categorizing sounds into meaningful groups helps listeners more efficiently process the auditory scene and is a foundational skill for speech perception and language development. Yet, how auditory categories develop in the brain through learning, particularly for non-speech sounds (e.g., music), is not well understood. Here, we asked musically naïve listeners to complete a brief (∼20 min) training session where they learned to identify sounds from a musical interval continuum (minor-major 3rds). We used multichannel EEG to track behaviorally relevant neuroplastic changes in the auditory event-related potentials (ERPs) pre- to post-training. To rule out mere exposure-induced changes, neural effects were evaluated against a control group of 14 non-musicians who did not undergo training. We also compared individual categorization performance with structural volumetrics of bilateral Heschl’s gyrus (HG) from MRI to evaluate neuroanatomical substrates of learning. Behavioral performance revealed steeper (i.e., more categorical) identification functions in the posttest that correlated with better training accuracy. At the neural level, improvement in learners’ behavioral identification was characterized by smaller P2 amplitudes at posttest, particularly over right hemisphere. Critically, learning-related changes in the ERPs were not observed in control listeners, ruling out mere exposure effects. Learners also showed smaller and thinner HG bilaterally, indicating superior categorization was associated with structural differences in primary auditory brain regions. Collectively, our data suggest successful auditory categorical learning of music sounds is characterized by short-term functional changes (i.e., greater post-training efficiency) in sensory coding processes superimposed on preexisting structural differences in bilateral auditory cortex.
