Re: old grey 2E Brainmaster amplifiers noticeable in delay in using Bioexplorer?

Mike,

It's been a while since I used my gray BrainMaster, but I don't believe there is

any way to get that to sample at 256, even in BioExplorer. I may be mistaken on

that, but I don't see anyplace to actually reset the sampling rate in

BioExplorer for the BrainMaster device. The BrainMaster+ device does allow you

to set sampling rates in the Device Properties.

I've never used the 800Hz sampling rate, so I really can't speak to that.

I'm not sure I understand your question about th 1/4 second feedback latency.

Many necessary items you add to a Design introduce some degree of delay, and you

can only try to minimize them. The sampling rate of the amplifier isn't one of

those things. It is more of a measure of the resolution or detail of the

signal. However many measures go into actually producing a signal, it is how

fast that signal gets through the software that results in latency. People like

believe that 1/4 second is a huge delay and would really affect the results of

feedback. Others believe that 1/4 second is faster than necessary and that the

brain can make sense of the information even with a greater delay (just as you

could understand what someone was saying even if you could only hear them in an

echo. I take a sort of middle ground that faster is better, but I don't make a

fetish of it, so I use 1/4 second as a reasonable target (based on an analysis I

saw several years ago of the delays involved in the process of the brain

processing anything it sends out which results in returning information).

Hope this helps.

Pete

this and most familiar with 2 channel training.
