“…However, while it is important to keep in mind that the limited spatial resolution of EEG requires a cautious approach regarding specific brain regions involvement, this finding was particularly evident in the frontal regions. Such a reduction of coherence is in accordance with previous studies that examined frontal inhibitory control by employing cortico-cortical communications during cognitive tasks (e.g., Müller & Anokhin, 2012;Schmiedt-Fehr & Basar-Eroglu, 2011;Shibata et al, 1998). Namely, in a Go/NoGo task, a higher level of EEG coherence was observed in the frontal regions when participants had to inhibit their response (i.e., NoGo condition) compared to the condition where no inhibition was required (i.e., Go condition).…”

“…Furthermore, relatively few studies have employed measures of cortico-cortical communication during such challenge (e.g., Müller & Anokhin, 2012;Schmiedt-Fehr & Basar-Eroglu, 2011;Shibata et al, 1998). The present study extends the examination of executive processes to the cognitive-motor domain while considering cortico-cortical communication between the frontal region and other cortical regions.…”

“…This difference could not be confirmed for the tested cognitive abilities (concentration, attention and visuo-spatial abilities). Nevertheless, for several cognitive abilities, such as executive functions, interhemispheric communication plays an important role (Sauseng, Klimesch, Schabus, & Doppelmayr, 2005;Shibata, Shimoyama, Ito, Abla, Iwasa, Koseki, et al, 1997;Shibata, Shimoyama, Ito, Abla, Iwasa, Koseki, et al, 1998). Beside numerous intrahemispheric connections, visuospatial abilities tested by mental rotation tasks, require interhemispheric associations as well (Bhattacharya, Petsche, Feldmann, & Rescher, 2001); the neural processes associated with attention are rather ambiguous.…”

The influence of physical activity on motor and cognitive performance has been approved in several studies. However, it is still unclear which functions are affected, and why. It also remains unknown what type of physical training is best suitable. The present study focuses on special movement aspects based on the Brain Gym ® program. Four groups of subjects (n = 64) participated in two experiments with pre-post intervention design. In experiment 1, two groups of subjects were exposed to a sensorimotor adaptation study design by executing center out pointing movements under distorted visual feedback conditions with their dominant and non-dominant arm to test for intermanual transfer (IMT) as pre-and posttest. The intervention in both groups consisted of specified movement exercises with the right and left extremities: participants of Experimental group executed movements crossing the body midline and participants of Control group movements without crossing the body midline. Results showed a decreased retention of adaptation but larger IMT for Experimental group during posttest. We conclude that movements crossing the body midline impede retention but enhance IMT of sensorimotor adaptation. A potential relationship to an improvement of communication between the cerebral hemispheres evoked by the movement exercises crossing the body midline is rather speculative. In experiment 2, two groups were exposed to the d2-test measuring concentration and attention and a dice-test testing for visual-spatial abilities as pre-and posttest. The interventions were similar to experiment 1. Results yielded no differences between groups such that different effects of both interventions could not have been shown.

“…The frequency or spectral contents of such signals display important information and have been used to evaluate the physiological and functional state of the nervous systems. Fourier analysis has been used extensively in studying the spectra of neurophysiological signals and in recent years interests have been focused on the study of synchronised phenomena between two or more events, such as the synchronisation between brain areas [2,31] and correlation between electroencephalogram (EEG), electromyogram (EMG) and magnetoencephalogram (MEG) [9,21,22,7]. In general, the investigated signals or data are assumed to be stationary and the estimates of the individual and cross spectra are calculated to obtain the coherence estimate.…”

Various time-frequency methods have been used to study the time-varying properties of non-stationary neurophysiological signals. In the present study, a time-frequency coherence using continuous wavelet transform (CWT) together with its confidence intervals are proposed to evaluate the correlation between two non-stationary processes. A systematic comparison between approaches using CWT and short-time Fourier transform (STFT) is carried out. Simulated data are generated to test the performance of these methods when estimating time-frequency based coherence. Surprisingly and in contrast to the common belief, the coherence estimation based upon CWT does not always supersede STFT. We suggest that a combination of STFT and CWT would be most suitable for analysing non-stationary neural data. In both frequency and time domains, methods to test whether there are two coherent signals presented in recorded data are presented. Our approach is then applied to the electroencephalogram (EEG) and surface electromyogram (EMG) during wrist movements in healthy subjects and the local field potential (LFP) and surface EMG during resting tremor in patients with Parkinson's disease. A software package including all results presented in the current paper is available at
