Objective. In this report we present the fEEGrid, an electrode array applied to the forehead that allows convenient long-term recordings of electroencephalography (EEG) signals over many hours. Approach. Twenty young, healthy participants wore the fEEGrid and completed traditional EEG paradigms in two sessions on the same day. The sessions were eight hours apart, participants performed the same tasks in an early and a late session. For the late session fEEGrid data were concurrently recorded with traditional cap EEG data. Main results. Our analyses show that typical event-related potentials responses were captured reliably by the fEEGrid. Single-trial analyses revealed that classification was possible above chance level for auditory and tactile oddball paradigms. We also found that the signal quality remained high and impedances did not deteriorate, but instead improved over the course of the day. Regarding wearing comfort, all participants indicated that the fEEGrid was comfortable to wear and did not cause any pain even after 8 h of wearing it. Significance. We show in this report, that high quality EEG signals can be captured with the fEEGrid reliably, even in long-term recording scenarios and with a signal quality that may be considered suitable for online brain-computer Interface applications.

“…Furthermore, they showed larger responses to tactile motion in the right posterior superior temporal sulcus (pSTS), pointing to crossmodal plasticity as a result of the early auditory deprivation. This is in accordance with findings from González-Garrido et al (2017) , who presented an oddball task with vibrotactile stimuli to early deaf participants ( n = 14; mean age = 21.96 years, SD = 6.63 years) and matched hearing controls ( n = 14; mean age = 21.93 years, SD = 5.02 years). Except for one native signer, all deaf participants acquired Mexican Sign Language (LSM) after the age of 7 years.…”

How do deaf and deafblind individuals process touch? This question offers a unique model to understand the prospects and constraints of neural plasticity. Our brain constantly receives and processes signals from the environment and combines them into the most reliable information content. The nervous system adapts its functional and structural organization according to the input, and perceptual processing develops as a function of individual experience. However, there are still many unresolved questions regarding the deciding factors for these changes in deaf and deafblind individuals, and so far, findings are not consistent. To date, most studies have not taken the sensory and linguistic experiences of the included participants into account. As a result, the impact of sensory deprivation vs. language experience on somatosensory processing remains inconclusive. Even less is known about the impact of deafblindness on brain development. The resulting neural adaptations could be even more substantial, but no clear patterns have yet been identified. How do deafblind individuals process sensory input? Studies on deafblindness have mostly focused on single cases or groups of late-blind individuals. Importantly, the language backgrounds of deafblind communities are highly variable and include the usage of tactile languages. So far, this kind of linguistic experience and its consequences have not been considered in studies on basic perceptual functions. Here, we will provide a critical review of the literature, aiming at identifying determinants for neuroplasticity and gaps in our current knowledge of somatosensory processing in deaf and deafblind individuals.

“…Computer-based auditory training program was found to be effective and can improve the overall hearing abilities [25]. Gonzalez-Garrido et al [6] found that training increases P300 amplitudes in both normal and deaf patients. We also found similar properties of P300 waves and its increase with education and perception with the literature.…”

Introduction Sensorineural hearing loss is a common problem, especially among geriatric patients, and it requires hearing aids. Unfortunately, most geriatric patients are hesitant to use hearing aids. Purpose of this study is to investigate whether computerized training therapies increase the attention and perception of patients who have been given hearing aids using psychophysiological tests and wave p300 records. Methods One hundred patients (40 women and 60 men) who used hearing aids were included in our study. Sixty patients (30 women and 30 men) received computerized training therapies with hearing aids. After the psychophysiological tests, the study group was divided into three groups according to the contributions of patients to training. Passive training was given in group 1; interactive training was given in group 2 and group 3 was composed of active, questioning training. Measurements of p300 wave latencies, stimuli-p300 peak and baseline-p300 peak were performed before and after training. The control group consisted of 40 patients who did not receive training and were treated with hearing aids only. Results We found a significant difference between the pre- and post-training measures of the p300 wave (p<0.001). Pre-training measurements of p300 waves were recorded for 12% in group 1; 9.1% in group 2 and 3 (p= 0.24). Post-training measurements of the p300 wave records were 80% in group 1; %72.7 in groups 2 and 3 (p= 0.22). Conclusion Attention and perception can be measured with p300 wave. All computer supported training programs showed an increase of p300 wave suggesting that attention and perception of patients with hearing loss can be increased with computer-supported education programs provided with hearing aids.
