Problems with long sessions

[itaizen]

I am conducting a research with and without pharmacotherapy which means every session takes about 3 hours.
(including a 1 hour break to wait after ingestion of the medication)

We are leaving the cap on and usually after the break (2 hours since the beginning) the electrode become very noisy...
Re-gelling helps but the data isn't good - especially on the electrodes of the left side.

I was wandering if there are any tips for improving data acquisition in long sessions?
Also, whether the more problems I have on the left side is due to my speciefic electrode set being too sensitive or maybe it is because the left has the CMS DRL electrodes???

Thanks!!!

Bundle the electrode cables together to minimize the included area of the cable loops.
