Electrophysiologic detection of the neurotoxic effects of acrylamide and 2,5-hexanedione in rats
Brain stem auditory evoked potentials (BAEP) and somatosensory evoked potentials (SEP), recorded from subcutaneously placed electrodes in anesthetized rats, were used to detect the neurotoxic effects of acrylamide and 2,5-hexanedione. Sixty adult male rats were equally divided into four groups: …

Assessing neurophysiological and behavioural outcomes of the proximal upper limb muscles in response to novel motor skill acquisition
… changes in neural activity, measured using somatosensory evoked potentials (SEPs) following a single session of motor training session with the proximal upper limb task. Additionally, sex-based differences in motor task performance were seen for the proximal upper-limb task, indicating a …

The effects of forward head posture on sensorimotor integration and neck and shoulder proprioception
… compared to individuals without. Study 2, used somatosensory evoked potentials to measure cortical activity related to sensorimotor integration following a motor learning task. This study was the first to report differential changes to SEP peak amplitudes in response to acute alterations in …

Differenzierung zwischen axonaler und demyelinisierender Schädigung bei Patienten mit Multipler Sklerose durch Untersuchung der hochfrequenten SEP-Komponenten nach Medianus-Stimulation
… cortical response (N20) in human median nerve somatosensory evoked potentials (SEPs). HFOs are generated both in deep axon segments of thalamo-cortical projection neurons and at the primary somatosensory cortex. To test the hypothesis that HFOs might be more sensitive to temporal dispersion …

Unterschiedliche Generierung niedrig- und hochfrequenter Komponenten somatosensorisch evozierter Potenziale (SEP) beim Menschen
Human median nerve somatosensory evoked potentials (SEP) contain a low-amplitude (< 500 nV) high-frequency (600 Hz) burst of repetitive wavelets (HFOs) which are superimposed onto the primary cortical response 'N20'. This study aimed to further clarify the cortical and subcortical structures …

Variabilität thalamischer und kortikaler Hochfrequenz (600 Hz) somatosensibel evozierter Potentiale durch Modulation des Aktivierungszustandes bei fokussierter Aufmerksamkeit
Human somatosensory-evoked potentials (SEP) recorded at the scalp after conventional electrical median-nerve stimulation contain a low-amplitude (<500 µV),high-frequency (~600 Hz) burst of repetitive wavelets, which are superimposed onto the primary cortical responseN20. Previous …

Investigation of the Clinical Utility of the Spatio-Spectral Dynamics of Sensorimotor ECoG in Response to Different Somatosensory Stimulation Modalities in Human Subjects
… visual assessment of the phase reversal of the somatosensory evoked potentials (SSEPs) is employed to delineate the central sulcus (CS). However, proper assessment of the phase reversal in the SSEP waveform is challenging due to the variations in the waveform morphology across subjects and the …

Zirkadiane Modulation hochfrequenter SEP-Komponenten (600 Hz) nach Medianusstimulation in Abhängigkeit von tonischer alertness
Human somatosensory evoked potentials (SEP) after median nerve stimulation contain a low-amplitude (< 500 nV) high-frequency (~ 600 Hz) burst of repetitive oscillations superimposed onto the primary cortical response “N20”, which can be obtained by digitally filtering the wide-band SEPs. Previous …

Assessment of neurological prognosis after cardiac arrest – clinical and neurophysiological aspects
… methods such as electroencephalogram (EEG) and somatosensory evoked potentials (SSEP), are often used because of their relative insensitivity to other organ failures. Aim: The aim was to evaluate a clinical routine change in TTM from 34°C to 36°C (Paper I) and prognostic accuracy, as well as the …
