questions on MindAffect cVEP BCI
by YuminosukeSato ·I was trying to use the mindaffect bci application, but I can't run it and get an error. So, is there any other application that can acquire brain waves with ssvep or p300? Brain waves are taken by -
I want to create a steady state of brain waves with light.
by wjcroft ·There are many posts here on the Forum and on Google on the "flashing light stimulation" modalities of BCI. These are called SSVEP, steady state visual evoked potentials. And cVEP, code-base -
EEG classification for EEG drones
by wjcroft ·cVEP of MindAffect is far superior to SSVEP based BCI. -
EEG classification for EEG drones
by YuminosukeSato ·Is it possible to classify brain waves by command only by brain waves such as moving the drone forward without using P300 or SSVEP? If possible, I'm currently using openBCI, cyton 16ch. Is there any g -
can synthesized speech be produced by processing EEG ?
by wjcroft ·VEP Visual Evoked Potentials, such as cVEP and SSVEP, which allow the user to place attention on an area of the screen that is 'flashing' at a certain rate. The measured visual response in the brain -
Multimeter tests of electrodes ?
by wjcroft ·have shown, certain EEG / BCI paradigms, such as SSVEP, cVEP, P300, will benefit from wet electrodes, because the signal to noise ratio can use all the help it can get. For example with the MindAffec -
ThinkPulse active electrodes, Q&A
by julienConscious ·know if this is the right place to discuss the SSVEP protocole here, and I'm not an expert in this but my first impressions for the dry electrode spectrum are 1/ your 7Hz peak is still here, with sim -
ThinkPulse active electrodes, Q&A
by lucasbaldezzari ·If you are not in ideal conditions, you might get a little more noise and then you might have to adjust the SSVEP parameters, like maybe increasing the duration of acquisition before identifying the -
ThinkPulse active electrodes, Q&A
by wjcroft ·but when I run my experiment, I can not see the SSVEPs (but I am pretty sure that there must be SSVEPs because when I use the gel cap for the same experiment I see them). So, I don't know what's goin -
ThinkPulse active electrodes, Q&A
by julienConscious ·it is possible to use dry electrodes for SSVEP. Hard to tell what's wrong here: the most common issue is that the hardware parameters are not correctly applied, as @retiutut mentioned it is sometimes -
ThinkPulse active electrodes, Q&A
by wjcroft ·Over on the other recent thread link below, @lucasbaldezzari remarks that he can use his SSVEP BCI acceptably with his gel based (wet) cap system. But when he uses DRY electrodes (either passive dry, -
Attempt at a Ganglion P300 Widget
by wjcroft ·There are other threads on the forum, explaining why SSVEP, xVEP monitor screen timing stability is so important: -
Attempt at a Ganglion P300 Widget
by lopezjuanma96 ·We had a similar issue when generating an SSVEP Stimulus inside a Widget, since when setting a certain frequency of stimulation, the period corresponding to that frequency wasn't accomplished on every -
SSVEP experiment, no FFT peaks found
by wjcroft ·I am assuming I may have to do additional preprocessing steps to better be able to infer the SSVEP frequency from the plots? -
SSVEP experiment, no FFT peaks found

SSVEP experiment, no FFT peaks found
by Marcus78 ·I had the limit of 200 Hz on the X axis, as I thought this may help to identify the SSVEP frequency because of the harmonics that may show? But okay I changed it: -
SSVEP experiment, no FFT peaks found
by retiutut ·If you're trying to do this manually it would help to lower the X axis limit to 50Hz or 75Hz. Next, it would be best to know what the SSVEP frequency being used was, rather than having us (and maybe y -
SSVEP experiment, no FFT peaks found
by Marcus78 ·I am currently working with EEG data acquired during an SSVEP experiment. I am still relatively new to the BCI domain, so I do not have a lot of experience yet. I am trying to determine what frequency
