Short-latency somatosensory evoked potentials in dystrophia myotonica.
Somatosensory evoked potentials (SEPs) were recorded in a group of 21 patients with dystrophia myotonica and in a group of controls. Those with dystrophia myotonica had longer absolute peak latencies due to slower peripheral conduction. SEP abnormalities revealed peripheral and/or central conduction delays in 33% of the dystrophia myotonica subjects. There was no apparent relationship between t...
متن کاملShort latency vestibular evoked potentials in the chicken embryo.
Electrophysiological responses to pulsed linear acceleration stimuli were recorded in chicken embryos incubated for 19 or 20 days (E19/E20). Responses occurred within the first 16 ms following the stimulus onset. The evoked potentials disappeared following bilateral labyrinthectomy, but persisted following cochlear destruction alone, thus demonstrating that the responses were vestibular. Approx...
متن کاملShort-latency somatosensory evoked potentials in degenerative and vascular dementia.
Short-latency somatosensory evoked potentials (SEPs) were recorded from 54 patients with dementia as compared to 32 age-matched controls. SEPs were generally normal in patients with senile dementia of Alzheimer type, while patients with multi-infarct dementia showed a prolonged central conduction time, an increased latency of both N13 and N20 and a reduction of the primary cortical response amp...
متن کاملCortical modulation of short-latency TMS-evoked potentials
Transcranial magnetic stimulation-electroencephalogram (TMS-EEG) co-registration offers the opportunity to test reactivity of brain areas across distinct conditions through TMS-evoked potentials (TEPs). Several TEPs have been described, their functional meaning being largely unknown. In particular, short-latency potentials peaking at 5 (P5) and 8 (N8) ms after the TMS pulse have been recently d...
متن کاملShort-Latency Brain-Computer Interface Using Movement-Related Cortical Potentials
In recent years, brain-computer interface (BCI) has been developing as a communication and rehabilitation tool for patients with neurological diseases, such as stroke and spinal cord injury. This system decodes the user’s intention from the brain signal, e.g. electroencephalography (EEG), and translates it into device commands. For either rehabilitation or communication system based on BCI, the...
