<div dir="ltr" class="">Hello,
<div class=""><br class="">
</div>
<div class="">First of all, thank you for developing this simulation
software as it is really useful for us researchers!</div>
<div class=""><br class="">
</div>
<div class="">I am a PhD student who will use tES soon, but both the
project and this stimulation/simulation literature is very new
to me, so I need some clarifications if you don't mind
helping. </div>
<div class=""><br class="">
</div>
<div class="">We have<a href="https://www.neurocaregroup.com/dc_stimulator_plus" target="_blank" moz-do-not-send="true" class=""> NeuroConn
DC-Stimulator-Plus</a> here in the lab, and I want to
stimulate hMT+ (V5) <b class="">bilaterally </b>with tRNS. The problem
is that only<u class=""> one-channel stimulation</u> is possible with
this device.</div>
<div class=""><br class="">
</div>
<div class="">First,</div>
<div class="">- Because I am going to use tRNS mode instead of giving a
direct current stimulation, I couldn't be sure that the
simulation I run on this software is applicable for tACS
experiments, especially for tRNS. If it is not applicable, is
there anything you can recommend to me to visualize tRNS
effect with one channel stimulation? I want to be sure about
the regions that will be affected by my stimulation, and if
tDCS simulations are not applicable for this, I need to find
another way. </div>
<div class=""><br class="">
</div>
<div class="">Second,</div>
<div class="">- If applicable for tRNS, when I run simulations for tDCS
-because of one channel stimulation- I saw that a huge area
between my two stimulation sites (probably around PO7-PO8
electrode regions) are substantially affected by stimulation,
regardless of the current applied. I am sure that you are much
more familiar with the procedure, so I wanted to ask if there
is anything you can recommend to do to stimulate <b class="">only
electrode positions </b>(and near areas of course) but not
the regions in between with tRNS, considering that I don't
have any chance to use multichannel systems. </div>
<div class=""><br class="">
</div>
<div class="">I have to note that the smallest electrodes I have are
rectangular 3cm x 3cm (and sponges), and new orders are
delivered to Turkey in several months which will,
unfortunately, affect my schedule. </div>
<div class=""><br class="">
</div>
<div class="">Any response and recommendation will be very helpful. </div>
<div class="">Thank you for your time, </div>
<div class=""><br class="">
</div>
<div class="">Kind regards,</div>
