Hi everyone, I'm a final-year engineering student working on an SSVEP-based BCI senior project and I'm considering combining the OpenBCI EEG Headband Kit with the PiEEG IronBCI board instead of an Ope

I recently purchased an OpenBCI system and am currently trying to start with using SSVEP. So far I have been unable to see a consistent spike in the FFT plot in response to stimuli.

Here is a December 2024 paper published on SSVEP research, using OpenBCI. You might find tips and suggestions to achieve the classification accuracy you desire.

Thank you for sharing the resources. I appreciate the insights and suggestions regarding SSVEP detection and the challenges involved. I did go through some of the threads mentioned and have reviewed t

There are a number of other threads here on the forum mentioning issues with SSVEP detection. Have you looked over those?

I have the same problem of 'Failing to see any SSVEP', but I’m working with the Cyton and Daisy boards to record SSVEP signals, but I’m failing to detect clear SSVEP responses in the frequency domain.

I've not had direct experience with PREP myself. Most of the comments here are the forum are related to visual evoked potentials (SSVEP, cVEP, etc.)

The Cyton board cannot detect SSVEP signal with wet electrodes or dry electrodes.

Also note that when flashing LEDs using square waves, other EEG non-dominant (harmonic) frequency components are generated. Which can confuse your FFT interpretation. I guess you could consider amplit

@cmello, please take a look at the multiple threads on the Forum, regarding the MindAffect cVEP system. This is generally superior to SSVEP, because it allows a substantial number of on-screen 'button

simply want to determine if detecting SSVEP is feasible with OpenBCI equipment as-is. Yes, using gel-based electrodes may yield better results, but that’s not the question here. The real question is

I can't comment on your motor imagery setup. But in general, MI is much less user friendly than other BCI paradigms such as SSVEP or cVEP. These latter systems allow many more choices for the operator

Did you view the cVEP (MindAffect) tutorial link posted earlier (by Pyotr Vosniak)? Best cVEP or SSVEP signal amplitude requires some skin moistness. This is done in the tutorial by coiling an absorbe

in Figure 1 and Figure 2. If you want to collect SSVEP data, which electrode is more effective? Can the second electrode simply press these two things together? Don't you need any additional accessor

Did you read some of the previous comments in this thread? In order for SSVEP timing to work, your stimulation source must be extremely accurate. Not all video monitors can provide this. Earlier comme

I have also encountered the same problem. The frequency of SSVEP data collected is completely incorrect, and the collected data seems to have some issues, as shown in the figure. Each interval data is

I've been playing around with ganglion chips and staring at various ssvep stimuli, however I've failed to achieve any entrainment or consistent peak at 10 hz with eyes closed. I've read previous posts

I'm not sure why you are commenting on this SSVEP thread. Eyes closed alpha is not the same as 'visual evoked potential' (VEP) issues. Best alpha production is on electrodes in occipital or parietal s
