ISI field

Hi Gerv,
Thanks for getting back to me so quickly. I can't find an ISI field under any of the configuration tabs. Is it known by any other name?
thanks,
Emily

Initial session error

Hi Gerv, When running the initial session with neuroscan I'm getting the following error. Warning: StimulusPresentationTask::Preflight: Due to a sample block duration of 40ms, the actual value of the ISIMaxDuration for stimulus 1 will be 1480ms rather than 1500ms. Warning: StimulusPresentationTask::...

Hi Gerv,
So does that mean you can use the dummysignal.exe for the initial session?
cheers,
Emily

Initial session batch and spatial filter

Hi Gerv, Can I just confirm with you; The batch files used for both the initial session (to determine the appropriate feedback channels) and for the actual feedback sessions (Mu 1dimensional 2 target) are the same apart from the task ie. StimulusPresentation.exe for the initial session and CursorTas...

Thanks Gerv, Can you clarify what I need to put in the offline analysis to get that information. The states I think I need to look at are states.TargetCode=1(bottom target), states.TargetCode=2 (top target), states.ResultCode=1 (hit bottom/miss top) states.ResultCode=2 (hit top/miss bottom) But I'm ...

cursor control

Hello, Is it possible that a user could be controlling the vertical cursor movement with eye movement for the 1D cursor task. For example glancing to the left may make the cursor move upward while staring straight ahead makes it move down? Do you generally record HEOG and VEOG so that you can identi...

It's working!!!

Dear Gerv, Juergen and Josh, Thanks for your prompt and helpful replies to my endless questions. The training on the 1D cursor task is going well :) . I can now see why using more electrodes is beneficial but I'll have to stick with the 16 for this project. One of my participants was at 80% accuracy...

Thanks Josh, Helped a lot, but I have more questions sorry. 1. Is there any benefit to having 2 channels for feedback in the 1D cursor with 2 target task. eg. entering the following in the linear classifier C3 12Hz 2 .5 C4 25Hz 2 .5 or are you better off just using one feedback channel for the 1D ta...

Hi Josh, Thanks that worked I’m able to view the .dat files now. I’m still confused though, I thought the idea was to compare rest with imagined or real movement to see where the greatest difference was and from that you could pinpoint the best spot to train mu? Is there any where I can find out wha...

Hi Gerv, I've checked the neuroscan parameters and everything is responding appropriately. Can I just clarify that you mean in the offline analysis for condition 1 put (states.TargetCode == 1) and for condition 2 enter (states.TargetCode == 2) and then enter (states.Feedback == 1) in the trial chang...
