In response to a question I was asked via private messaging on signal smoothing, I think it may help anyone trying to build their own ILF NF "In the othmers method they mention that they do Neurofeedback with the actual signal without any modific…

I found out that a low pass filter leads to a better training effect than a band pass filter, maybe because the signal has more information in it, so I reverted back to a low pass filter
-
What happens in practice is quite the opposite, whenever they went lower in frequency the effects became stronger to the point where they can calm a person down in minutes and also the reverse if the frequency is not well optimized What the ILF m…

Regarding the inhibits, the way they work is by having multiple inhibit bands each band covering a small range of frequencies, (1 - 3.5), (3.5 - 6), (6 - 8), (8 - 10), (10 - 12), (12 - 15), (15 - 18), (18 - 22), (22 - 28), (28 - 35), (35 - 45), You …

The signal is DC coupled by default, that's why the signal amplitude reaches thousands of microvolts, thats the DC offset, if you want to filter it you need a high pass filter at 0.3 or 0.5 hz, then you will get a signal in the tens of microvolts ra…

I am using the defaults in Bioera Filter element
-
No I am using the formula 1.5 x Training frequency, I think the center frequency only applies in band pass filters we are using a low pass filter so the cutoff frequency is 1.5 x 1.3 mhz
-
I am using a low pass filter with default settings and the voltage values when the design starts begin at 0 and gradually goes up depending on the frequency you use, it can go to 3 - 4 millivolts in 1 - 2 minute and then reverses direction to 0 if y…

This is the technical part, but this part is not the important part, the really important part is knowing what locations to train for which symptoms, and how to choose the optimal frequency, how to know if you should go lower or higher, what's the s…

I have used Cyton with Bioera to create multiple Infra-low Neurofeedback designs following the Othmers method and with very successful results, I am sure it works because I was getting the same results they are reporting in the symptom profiles in t…

Thanks a lot William, I will give it a try and let you know
-
I updated my previous comment, Can you please take a look and let me know which legs to solder together?
-
The cyton switch is not as simple, it has 8 legs and I am not sure which legs to solder together?
-
To clarify another point, After pasting the url from chipkit under File->Preferences in "Additional Boards Manager URLs", You have to click on the Boards Manager and wait for the list to populate, then scroll down to chipkit, choose versio…

Hi, I followed the instructions here https://docs.openbci.com/Hardware/05-Cyton_Board_Programming_Tutorial You need to have the Arduino IDE installed and then follow the instructions here to add the OpenBCI board to the Board Manager list ht…

Thanks William, I will give it a try and let you know if I ran into any issues
-
Thanks, Yes I am using Ag-AgCl electrodes
-
Does that mean that I don't need to worry about electrode impedance with the ADS1299? As long as I am not getting 50/60 Hz noise then I am fine? In the Othmer method course they stress upon doing an impedance check before starting the session, …
-
Thanks a lot, can you check the impedance of SRB2?
-
You may be correct about the high pass modification, they do mention in the Othmer method research that they use both a high pass and low pass filter and consider the training frequency the middle frequency between both cutoff frequencies, so to tra…
-
I am not sure what an additional high pass filter will accomplish? going lower in frequency for Infra Low Neurofeedback purposes means limiting higher speed signals that may cause arousal symptoms such as anxiety ...etc and sticking to slower signal…
-
ok I think I understand the reason, the time response of the filter at such low frequencies is very large reaching tens and hundreds of thousands of seconds, that is why the signal amplitude is increasing very slowly over hours, so to make it reach …
-
No it's a low pass filter so everything below 0.01 mHz for example
-
could it be a time constant (time response) of the filter since the frequency is very low, the time response of the filter is (1/2πf) could reach hundreds to thousands of seconds, is this correct?
-
I don't mean that the signal is Uni directional, I mean that it's Uni-directional within the 30 min session as it takes hours to days to complete a full cycle, I have read the protocol guide and I have done/witnessed many sessions and I understand t…
-
I have watched the On Demand Intro course and the Advanced Summit and I understand the method quite well, however I can't afford and don't have the qualifications required to buy the Neuroamp/Cygnet, so I decided to build my own system, I am a softw…
-
Yes, I connected the electrodes to myself and got a signal on Bioera, thanks

OK, I believe this a serious quality issue, the board had no firmware installed, I reinstalled the firmware and it now works, but this shouldn't happen, as mentioned on the store the board should come with the firmware installed
