“…In addition, GBA is synchronized among different brain areas, e.g. in the visuospatial matching process between occipital and parietal lobes, and in the preparatory stage for motor responses to visual stimuli between the frontocentral and parietooccipital lobes [4,5,7,8,9,10,11,12,13,15,16,27]. Generally, GBA was found to be increased in association with cognitive processing in these studies.…”

“…They suggested that GBO of early latency may be related to a process of discrimination of stimuli, while GBO of late latency may be related to a process of execution of finger movement associated with go stimuli or a process of inhibition associated with no-go stimuli. On the other hand, Harmony et al [27] proposed that the difference between conditions was observed in the synchronization increases of the γ band between 33 and 36 Hz in the go condition, whereas synchrony decreased at these frequencies in the no-go condition; these differences may be due to the preparation and execution of the motor response during the go condition and its inhibition in the no-go condition. In our study, there was no stimulus ERS in the go condition, but ERD between 33 and 36 Hz at Cz in the no-go condition was observed similar to their report [27].…”

“…However, event-related synchronization (ERS) and event-related desynchronization (ERD) are relative changes in the power of any frequency band during either external or internal stimulus processing. Several studies have measured ERDs/ERSs using a go/no-go paradigm [23,24,25,26,27,28]. The aim of this study was to evaluate differences in visual-motor integrated processing between execution and inhibition of motor responses using ERSs and ERDs of high-frequency electroencephalography (EEG) activity, and to investigate a relationship between ERPs and ERS/ERD in normal subjects.…”

Objective: High-frequency electroencephalography (EEG) activity has been observed in association with cognitive processing, including stimulus perception, consciousness and selective attention, in humans. The aim of this study was to compare visual-motor integrated processing between execution and inhibition of a motor response using event-related synchronization (ERS) and desynchronization (ERD) in the 15- to 80-Hz range and to investigate a relationship between event-related potentials (ERPs) and ERS/ERD in 10 normal young subjects. Methods: EEGs were recorded from 21 scalp sites during a visual go/no-go paradigm. For ERPs, 40 artifact-free trials were averaged off-line referenced to linked ear lobes. In the β and γ bands, ERS and ERD were calculated by time-frequency analysis. Results: Go N2 and no-go N2 were elicited 200-250 ms after stimuli, and their distributions were predominant at Fz. Go P3 was predominantly elicited 340-360 ms after stimuli at Pz, whereas no-go P3 was predominantly elicited 360-380 ms after stimuli at Cz. ERD of the β band at Fz and Cz during 300-600 ms showed in the go condition, whereas ERD showed between 39 and 42 Hz at F3 in the no-go condition. Conclusion: Oscillatory cortical response-related β and γ activities differ between the processing of execution and inhibition in motor responses. β ERDs in the sensorimotor areas with go stimuli may be related to motor responses, and γ ERDs in the left frontal area with no-go stimuli may be involved in the processing of inhibition of motor responses.

“…This wave is usually modulated by correctly or incorrectly inhibited responses, with larger amplitudes for unsuccessfully stopped (US) than for successfully stopped (SS) responses (Dimoska, Johnstone, & Barry, 2006;Kok et al, 2004;Ramautar et al, 2006). Time-frequency data have shown that the N2 is associated with theta oscillations (around 4-7 Hz) over fronto-central scalp areas, an activity also related to conflict detection and error processing (Harmony, Alba, Marroquín, & González-Frankenberger, 2009;Harper, Malone, & Bernat, 2014;Kirmizi-Alsan et al, 2006;Luu, Tucker, & Makeig, 2004;Müller & Anokhin, 2012). The neural generator of the N2 is presumed to be located around the dorsal portion of the anterior cingulate cortex (Botvinick, Cohen, & Carter, 2004;Braver, Barch, Gray, Molfese, & Snyder, 2001;Nieuwenhuis, Yeung, van den Wildenberg, & Ridderinkhof, 2003).…”

It has been suggested that mental rehearsal activates brain areas similar to those activated by real performance. Although inhibition is a key function of human behavior, there are no previous reports of brain activity during imagined response cancellation. We analyzed event-related potentials (ERPs) and time-frequency data associated with motor execution and inhibition during real and imagined performance of a stop-signal task. The ERPs characteristic of stop trials-that is, the stop-N2 and stop-P3-were also observed during covert performance of the task. Imagined stop (IS) trials yielded smaller stop-N2 amplitudes than did successful stop (SS) and unsuccessful stop (US) trials, but midfrontal theta power similar to that in SS trials. The stop-P3 amplitude for IS was intermediate between those observed for SS and US. The results may be explained by the absence of error-processing and correction processes during imagined performance. For go trials, real execution was associated with higher mu and beta desynchronization over motor areas, which confirms previous reports of lower motor activation during imagined execution and also with larger P3b amplitudes, probably indicating increased top-down attention to the real task. The similar patterns of activity observed for imagined and real performance suggest that imagination tasks may be useful for training inhibitory processes. Nevertheless, brain activation was generally weaker during mental rehearsal, probably as a result of the reduced engagement of top-down mechanisms and limited error processing.

Abstract.A visualization methodology for the analysis of dynamic synchronization in electroencephalographic signals is presented here. The proposed method is based on a seeded region-growing segmentation of the time-frequency space in terms of spatial connectivity patterns, a process that can be fully automated by cleverly choosing the seeds. A Bayesian regularization technique is applied to further improve the results. Finally, preliminary results from the analysis of a high electrode-density dataset with 120 channels are shown.
