Cortical activity during preparation and inhibition of responses to balance perturbations

Falling is one of the major causes of unintentional death or injury worldwide. People older than 65 years and people suffering from neurological disease have a higher chance of falling, which indicates the involvement of higher brain structures such as the cortex. For this reason, cortical activity underlying balance control has been subject of...

Continuous Impedance, Force, and Acceleration Monitoring for Motion Artefact Reduction in EEG

Electroencephalograph (EEG) is used in various applications such as diagnosing patients suffering from epilepsy or seizures. Motion artefact is the noise recorded together with the desired biopotential signals. It is mainly introduced by the relative motion between the measurement electrode and the human scalp. Dry electrodes are preferred in...

Corticomuscular communication study by using current source density analysis

Corticomuscular communication during wrist motor tasks was investigated in this study. EEG signals from the sensorimotor cortex and EMG data from the reflexive carpi radialis and extensor carpi radialis muscles were recorded from five healthy subjects while performing visual-motor force tasks, with and without perturbation on the wrist....
