The aims of this study were (1) to characterise the extent and nature of disrupted sleep in individuals with long-term sleep complaints subsequent to mild traumatic brain injury (MTBI), and (2) to determine whether sleep disturbances in MTBI subjects were more characteristic of psychophysiological, psychiatric, or idiopathic insomnia. ⋯ Sleep disturbances can persist well after the injury in a subset of patients with MTBI.

Theta burst transcranial magnetic stimulation (TBS) causes changes in motor cortical excitability. In the present study, somatosensory-evoked potentials (SEPs) and high-frequency oscillations (HFOs) were recorded before and after TBS over the motor cortex to examine how TBS influenced the somatosensory cortex. ⋯ The mechanisms of changes in HFOs after TBS may be the same as those in SICI.

This study investigated if obstructive sleep apnea syndrome (OSAS) may be associated with higher activity in different frequency bands of the EEG during a sustained wakefulness paradigm. ⋯ In a sustained wakefulness paradigm, higher activity in delta, theta and beta bands associated with OSAS indicates that OSA patients show marked signs of higher sleepiness and stronger efforts than controls to stay awake, even though they tend to underestimate their sleepiness.

Retrospective evaluation and comparison of performances of a multivariate method for seizure detection and prediction on simultaneous long-term EEG recordings from scalp and intracranial electrodes. ⋯ This study evaluates simultaneously recorded non-invasive and intracranial continuous long-term EEG data with respect to seizure detection and seizure prediction for the first time.

To investigate the changes in cortical excitability of the human motor cortex induced by high-frequency repetitive transcranial magnetic stimulation (rTMS) of different stimulation durations. ⋯ The results have important implications for the selection of stimulation parameters other than the frequency of rTMS. The clinical application of rTMS for the purpose of motor enhancement should be considered along with the mechanism of different stimulation parameters.
