My neuro PT in Denver told me to stop chasing big signal gains and it actually made my BCI setup usable
I got my first EEG headset about 8 months ago for a simple cursor control project and spent the first few months cranking gain and adding electrodes because I thought more signal equals more control. My neuro PT in Denver (she works with stroke rehab patients) told me to drop to 4 channels and stop chasing amplitude, just focus on steady repeatable patterns. I ignored her for like 3 weeks, kept getting jittery cursor jumps, then finally tried it and got my best 2-class accuracy yet, around 84 percent on a 20 minute session. The weird part is my headset has 16 channels and I now only use a quarter of them for this task. I'm wondering if anyone else here has had a clinician or engineer tell them to simplify and been surprised it worked. Also curious what channel count you all actually run for motor imagery, because I feel like I'm leaving something on the table.
