Guest guest Posted December 26, 2003 Report Share Posted December 26, 2003 , Good question. This is an area of common confusion. To begin, monopolar or bipolar placements are always only in one channel. I think you are confusing bipolar placement--an active and a reference electrode in one channel--with two-channel training--active and reference electrodes in two separate channels. You can combine two monopolars or two bipolars or a monopolar and a bipolar in two channels, but each channel must be either monopolar (referential) or bipolar (sequential). Monopolar would be a montage in which the active lead was over an active EEG site (on the head), and the reference lead was over a relatively inert EEG site (e.g. the earlobe or the mastoid bone). A bipolar montage is one in which both active and reference leads are placed over active EEG sites. So Cz/A1 is monopolar. Cz/Fz is bipolar. It makes no difference where you place the ground, because the ground lead does not read EEG. Whenever we measure EEG, we are measuring the difference between two sites. Our training machines are called "differential amplifiers" because they amplify the difference between the signal reported at one lead and the signal reported at the other. This does not actually mean that we are measuring exactly what is happening at, say, Fz and subtracting it from what is happening at Cz. What we actually measure is specific types of activity occurring between the two sites and the background signal from the whole head. So a Cz/A1 placement in fact measures the activity occurring between the two sites. So does a Cz/Fz placement. If Jim wants to check this out scientifically, try this: Put a lead at Fz, another at Cz and one at A1. Plug them in with Cz active, A1 reference and Fz ground (remember, it is not reading EEG). Take a look at the signal for a couple minutes, maybe one eyes open and one eyes closed. Then pause the data and switch the reference and ground leads. Now you have Cz/Fz with A1 as your ground. Gather another couple minutes. Unless you are working with an unusual head, you'll see very different signals in these two trials. Most likely you'll have much higher amplitudes in the first (monopolar) hookup at Cz/A1, because you are subtracting a relatively inactive site (the earlobe) from an active site. In the second (bipolar) hookup at Cz/Fz, you are subtracting an active EEG reading from another active EEG reading, so the difference should be smaller. Hope this helps. Pete Training question Hi Pete, Jim and I have a different idea of what we were training, so I thought I'd ask you. When we train a site like CZ with reference to A1 and ground to A2, Jim says we are training only CZ. I say we are measuring and training the difference between CZ and A1 reference. Likewise, if we train CZ/FZ/A2, Jim says we are training only CZ, and I say we are training the difference between the area between CZ and FZ. He says you aren't training two areas or the difference between two unless you use a bi-polar placement. I say if you use bi-polar you are training two sides of the brain at the same time and the difference between the active and reference on both sides. Can you clarify this understanding for us.

Guest guest Posted October 12, 2004 Report Share Posted October 12, 2004 Dawn, I think some people respond better to autothresholding than others. I personally don't. I'd suggest trying a manual and see if it works better. Foxx -----Original Message-----From: Dawn [mailto:spreck11@...] Sent: Monday, October 11, 2004 7:41 AM Subject: Training Question I have a question about setting the thresholds for training in Bioexplorer. I'm doing a basic one channel, 1 reward (SMR), 2 inhibit (theta, hibeta) protocol. I was told to set the 2 inhibit channels to manual thresholds and let the reward channel autothreshold. With each session, I am slowly lowering the inhibit thresholds, but I am not getting very high amplitudes in the reward channel with the autothresholding, although I am getting a lot of positive feedback. Should I try setting a slightly higher manual threshold on the reward channel to make the sessions more challenging. Is there some reason why autothresholding is better in the reward channel? Thanks, Dawn M. still struggling to get this hometraining right Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 13, 2008 Report Share Posted September 13, 2008 I think I got to close to seeing it happen twice yesterday. Picture you being HLO, landing the chopper no worries. Pax, disembark and you notice a pink fluid (transmission oil) leaking from the under carriage. You tell the co-pilot who get's out, wipes the under cariage section involved with his hankerchief gives you the thumbs up and get's back in the chopper. You load the outgoing pax up the chopper lifts off and you can actually see the leak in under carriage again. 1 hour later you stand on the heli deck again awaiting comms with the chopper. Low and behold, the same chopper calls up. Yet again, you go through the whole motions and point out this time, a much faster leak. Again, thumbs up from the pilot and co-pilot.......
