The Somatosensory Evoked Potential

[Somatosensory evoked potential in experimental intracerebral hemorrhage].

Somatosensory evoked potential findings in ankylosing spondylitis.

OBJECTIVE Somatosensory evoked potential (SSEP) abnormalities were reported in patients with ankylosing spondylitis (AS). This study aimed to investigate SSEP abnormalities and its relation with clinical findings in AS patients. MATERIALS AND METHODS The study included 26 patients with AS and 17 age-matched health volunteers (Control for SSEP). Median nerve SSEP findings were normal in all AS...

Intra-operative somatosensory-evoked potential monitoring.

PURPOSE To evaluate the usefulness of intra-operative somatosensory-evoked potentials (SSEPs) in monitoring spinal cord status via the posterior tibial nerve. METHODS 84 men and 28 women aged 16 to 66 years (72% were aged 20 to 40 years) with spinal trauma (63 in the lumbar and 49 in the thoracic spine) underwent posterior instrumentation and fusion using bone grafts. All 63 patients with lum...

Topographic distribution of the tibial somatosensory evoked potential using coherence.

The objective of the present study was to determine the adequate cortical regions based on the signal-to-noise ratio (SNR) for somatosensory evoked potential (SEP) recording. This investigation was carried out using magnitude-squared coherence (MSC), a frequency domain objective response detection technique. Electroencephalographic signals were collected (International 10-20 System) from 38 vol...

Haptic BCI Paradigm based on Somatosensory Evoked Potential

A new concept and an online prototype of haptic BCI paradigm are presented. Our main goal is to develop a new, alternative and low cost paradigm, with open-source hardware and software components. We also report results obtained with the novel dry EEG electrodes based signal acquisition system by g.tec, which further improves experimental comfort. We address the following points: a novel applic...
