“…Abundant research has documented these old/new differences in ERPs, but the effects of the decision criteria (or the resulting response bias) on the ERPs recorded during the execution of recognition memory tasks have rarely been investigated5 ) . Lee et al6 ) reported, however, that the latencies of N100 and P300 were shortened and that their amplitudes increased in both the Fp1 and Fp2 areas after transcranial direct current stimulation (tDCS) applications. The P300 wave occurs only if the subject is actively engaged in the task of detecting the targets7 ) .…”

[Purpose] The purpose of this study was to examine the effects of galvanic vestibular stimulation on event-related potentials. [Subjects and Methods] Forty normal female adult subjects were randomly distributed to a galvanic vestibular stimulation application group (20 subjects) and sham group (20 subjects). For galvanic vestibular stimulation application, a positive electrode was applied to the right mastoid process, and a negative electrode was applied to the left mastoid process; simulation was applied for 10 minutes. A test was conducted on the N100 and P300 components of the event-related potentials before and after galvanic vestibular stimulation. [Results] The N100 latency showed statistically significant differences in interaction effects between time and group in the F3, F4, Fz, and Pz areas. The P300 latency showed the same results in the Fp1 and Fp2 areas, the N100 amplitude showed the same results in the Fp2, Fz, and Pz areas; and the P300 amplitude showed the same results in the Pz area. [Conclusion] These results suggest that galvanic vestibular stimulation may play a positive role in the N100 and P300 components of the event-related potentials of the cerebral cortex related to decision-making in matching words with images.

“…Partially as a consequence of this, very little research has looked at the effect of tDCS on P300 potentials and how tDCS may help facilitate the P300 response. Although not directly related, Antal (Antal, et al, 2004) reported measurable tDCS effects on Visual Evoked Potentials (VEP) with Lee and co-workers reporting measurable effects of tDCS on latency and amplitude (Lee, et al, 2014). In this paper we explore two experiments conducted by our team which appear to reveal that tDCS can have an important effect in enhancing cognitive responses that are crucial to BCI application (Izzidien et al, 2016;Ramaraju et al, 2018).…”

In this workshop paper, we present two of our team's findings on the effect of brain electrical stimulation on BCI performance, reflecting a trend in neuro-engineering research. In many applications, BCI technology targets users with impaired neural activity and as such enhancement of such activity can be of great importance. We show that the application of transcranial direct current stimulation (tDCS) can significantly enhance an EEG potential (P300) which is used in BCI spellers. In addition, tDCS application also appears to improve working memory performance particularly relating to the recall of shapes.

We aim to measure the postintervention effects of A-tDCS (anodal-tDCS) on brain potentials commonly used in BCI applications, namely, Event-Related Desynchronization (ERD), Event-Related Synchronization (ERS), and P300. Ten subjects were given sham and 1.5 mA A-tDCS for 15 minutes on two separate experiments in a double-blind, randomized order. Postintervention EEG was recorded while subjects were asked to perform a spelling task based on the “oddball paradigm” while P300 power was measured. Additionally, ERD and ERS were measured while subjects performed mental motor imagery tasks. ANOVA results showed that the absolute P300 power exhibited a statistically significant difference between sham and A-tDCS when measured over channel Pz (p = 0.0002). However, the difference in ERD and ERS power was found to be statistically insignificant, in controversion of the the mainstay of the litrature on the subject. The outcomes confirm the possible postintervention effect of tDCS on the P300 response. Heightening P300 response using A-tDCS may help improve the accuracy of P300 spellers for neurologically impaired subjects. Additionally, it may help the development of neurorehabilitation methods targeting the parietal lobe.
