Gastric Slow Wave Propagation

The gastric slow wave (ECA) originates in the proximal stomach and propagates distally towards the pylorus. For recording, place multiple surface electrodes on the abdomen along the gastric axis and connect them to respective EGG100C amplifiers that have a common reference electrode placed near the xiphoid process. For consistent electrode-to-electrode spacing, use the EL500 dual electrodes with LEAD110 leads. For extremely tight electrode-to-electrode spacing, use the EL254 or EL258 reusable Ag-AgCl lead electrodes. The signals amplified at each electrode will be displayed on consecutive channels in AcqKnowledge. For manual measurements, use the cursors to evaluate waveform differences. For automated timing analysis, run the Peak time detector on one channel and search the remaining channels for their respective peak times. To verify the delta time consistency, automatically calculate the difference in peak times between the channels.

New Citations | Utilizing VR and AcqKnowledge to Reduce Stress

 Impact of Green Space on Stress Reduction Research studies show that the increased exposure of urbanization, traffic noise and pollution has been correlated with increasing levels of stress. However, do greener, more natural environments provide the opposite effect, restoring human well-being and contributing in stress reduction? Researchers compared user experiences in Virtual Reality (VR) scenes […]
