SpletResults: On the clavicle, the upper and middle parts of SCM from all subjects, air-conducted short tone burst evoked biphasic responses (p13–n23). VEMPs recorded at the upper part of the muscle showed the largest amplitude, followed by that at the middle part. However, the latency of the first peaks (p13–n23) was not constant in the upper part. SpletThe development of short latency vestibular evoked potentials (VsEPs) was investigated in the neonatal rat. Using the appropriate stimulus (linear or angular acceleration impulses) …

As new research and clinical experience broaden our knowledge, changes in treatment and drug therapy are required. SpletResponses evoked by STBs in patients were compared with responses evoked by clicks. RESULTS: In all normal subjects, STBs (0.5, 1, and 2 kHz) evoked biphasic responses on the SCM ipsilateral to the stimulated ear; the same was true for clicks. Short tone bursts of 0.5 kHz evoked the largest responses, while STBs of 2 kHz evoked the smallest. affini linea retta

SpletOne of the observations from our work was that there were two distinct groups of short-latency vestibular-dependent evoked potentials (VsEPs), which cooccurred in anterior and posterior electrodes (Todd et al. 2003). In anterior locations, the VsEPs were labeled N15/P21 vs. P10/N17 in posterior locations. SpletSubsequently, electrophysiological examination through somatosensory evoked potentials (SSEP) assessment of the labia majora was performed. The labia majora were stimulated with bipolar surface electrodes (cathode proximally) at an intensity of two times the sensory threshold, with stimulus duration of 0.2 ms and a frequency of 2 Hz.
