Studying oscillations is an important part of the analysis, as they are thought to provide the underlying mechanism for communication between neural assemblies. Traditional methods of analysis, such as Short-Time FFT and Wavelet Transforms, are not ideal for this task due to the time–frequency uncertainty principle and their reliance on predefined basis functions. Empirical Mode Decomposition and its variants are more suited to this task as they are able to extract the instantaneous frequency and phase information but are too time consuming for practical use. Our aim was to design and develop a massively parallel and performance-optimized GPU implementation of the Improved Complete Ensemble EMD with the Adaptive Noise (CEEMDAN) algorithm that significantly reduces the computational time (from hours to seconds) of such analysis. The resulting GPU program, which is publicly available, was validated against a MATLAB reference implementation and reached over a 260× speedup for actual EEG measurement data, and provided predicted speedups in the range of 3000–8300× for longer measurements when sufficient memory was available. The significance of our research is that this implementation can enable researchers to perform EMD-based EEG analysis routinely, even for high-density EEG measurements. The program is suitable for execution on desktop, cloud, and supercomputer systems and can be the starting point for future large-scale multi-GPU implementations.}, year = {2023}, eissn = {1424-8220}, orcid-numbers = {Juhász, Zoltán/0000-0003-0677-8588} } @article{MTMT:34072577, title = {Event‐Related Spectral Perturbation, Inter Trial Coherence, and Functional Connectivity in motor execution: A comparative EEG study of old and young subjects}, url = {https://m2.mtmt.hu/api/publication/34072577}, author = {Gyulai, Ádám and Körmendi, János and Mohamed, F.

The research goal of our lexical decision experiments is to gain information about the temporal characteristics of recognition at the orthographic, phonological, and semantic levels of processing. The research questions concern behavioral differences and the ERP components of recognizing English words, Hungarian words, and interlexical homographs. 23 Hungarian-English bilingual participants were tested in an Electroencephalogram laboratory. In recognition of Hungarian and English words and homographs, the mean response language per participant indicated high accuracy for both Hungarian and English conditions (96% and 98%, respectively). In contrast, the homographs are biased towards English responses (27% Hungarian response). The multiple comparisons confirmed no difference in the mean response times of Hungarian and English words, whereas the interlexical homographs produced around 150 ms longer responses. In recognition of Hungarian and English words, there was no difference between the two categories in the early recognition phases, corresponding with the orthographic-phonological level. However, the neural representation of the two languages differed, later reflecting the differences in semantic or decision-related processes. In the case of the Hungarian- English interlexical homographs, the ERP waveforms did not show significant differences between the items perceived as English or Hungarian. Although there is a difference between the brain activations in the temporal and frontal electrode sites, this difference is insignificant. These data coincide with the former findings related to the homograph effect (Navracsics & Sáry, 2013), which explains that participants are exposed to a greater cognitive burden in the recognition, and the reaction time is longer due to the fact that both lexicons are active.}, year = {2023}, eissn = {2498-4442}, pages = {36-58}, orcid-numbers = {Ihász, Petra/0000-0003-3515-8230; Juhász, Zoltán/0000-0003-0677-8588} }
