Here's an alternative idea: If you don't want to mix up gelatins or make a phantom head - go to the butcher and buy $5 worth of pig skin. Then attach a function generator to that. https://ieeexplore.ieee.org/abstract/document/8717106 "tACS gener…

@wjcroft said: Here are two projects / papers discovered by Scott Yuen last week: https://www.mdpi.com/1424-8220/21/14/4658/htm "A Long-Lasting Textile-Based Anatomically Realistic Head Phantom for Validation of EEG Electrodes" …

Roger. Request coming shortly

What kind of purchase info is needed? In our case, we are a government agency and the purchase was made by another person (an admin). All we will know is the date it was ordered, what was on the order and what they probably said the company name is…

Our experience is that anything over ~5-6% filler is pretty stable. If you haven't seen it already, there is more information on the formulation process and mechanical properties here: https://journals.plos.org/plosone/article?id=10.1371/journal.po…

We will gladly partner with any company who wants to do it, and help you do it - we do tech transfer all the time, and collaborate with private companies often. But ARL is not in the business of "making stuff", or making money. We do foundational re…

By the way, overall, straight up correlation is a terrible statistic to tell you if two electrodes are similar. The problem is that large amplitude, low-frequency trends that are in common will greatly dominate the statistic. It is better to use so…

It's not that simple. Overall, in a static condition, the signal characteristics of COTS dry electrodes are fairly similar to wet gel based electrodes. This is assuming you use the same amplifier for both. But this statement is not universal. Wher…

I agree 100% w/ @wjcroft. Are they really going to play a hockey game? I am going to guess you are not part of a university b/c no human use IRB would allow this. There are major safety concerns. Any conventional electrodes placed under the helmet…

Hiroki, you need to please clarify what it is that you really want to know. Do you mean that you want to see the correlation between dry and wet electrodes, using the same amplifier? You really should never compare the data from one amplifier (e.g…

There's a registration button in the upper corner. However - looks like it's now full. Temple University Hackathon registration, http://www.tubrainhack.com/registration-full/

Bump up. Salary actually starts at $76K U.S., plus insurance and travel expenses

The latest generation, and future upcoming dry electrodes are much better than what used to be available. The good news is that, based on what I've seen in the research world, it;'s a good bet that within 2 years dry electrodes will be readily avai…

Yep, I'd liek to echo Chip's sentiment re: the necessity for real head-like phantoms. They are incredibly useful in that form factor b/c it means you can fit any device to it, but for simple testing it isn't critical. What is important though is tha…

Wow, ok so this wasn't intended to end up as a plug for our own work... but... thanks! Zeynep and Scott Makeig are collaborators of ours, actually our lab partly sponsored that paper ;-) Really I just want to get some discussion going on what peopl…

The native system does not inherrently have a manner for external 3rd-party stimulus integration (e.g. triggers). Generally, the idea is that you se the same program for data acquisition and stimulation. one classic way to get around this is to sa…

Jetster, I'd just like to clear up a few things for future reference. "Dry" and "Active" are completely independent technologies. Dry typically just means no gel (although some mfrs use it to mean no classic gel, but the sensor may still be self-…
