14. Save this 30 second assessment and a few other longer period samples that seem to have had little
artefact. You may want the director to look at one of these later. (This is a good practice from time to
time in order to review the EEG in the light of electrode placements and enhance and inhibit bandwidths.)
15. When you are back at the display screen you can enter ‘Edit’ to change channel settings or click
‘Options’ to choose statistics. This time click ‘change channel set’ on left side box and go half way
down and see a list of band widths % time > C. C is short for constant. This will be the threshold for
the % time > threshold computations on some of the screens. Highlight the ones you have stats for one
at a time. In the right hand column the preset constant (a number) pops up. – Change it to the average
MEAN – that you wrote down for your client for that frequency band-width.
Then do a save by clicking box below it (but don’t click the second box at the bottom which
would change the constant to original channel set). Do this for each of the bands theta-delta,
3-10, SMR, problem solving beta … then close. It will save it to your client’s name.
16. Use your mouse to get back to the screens (or hit enter) and run any screens of the 5 you
chose originally for this client (#s 1-5).
17. You can change the threshold either using your mouse over the threshold line’s end or by
left clicking over the instrument (a red line appears outlining that bargraph) then going to the
top above the display and clicking the ‘thr’ box and changing the number. NOTE: THIS
threshold # controls the points for that instrument and the sound and the display animation
but NOT the %>threshold computation. (That you set a “C” constant for.)
18. You can change the scale making it a larger range or a smaller range. You do this by
clicking over the bargraph and then changing the number at the top of the screen.
19. If you are looking at respiration and pulse change the time from the “5 second” default to 30
seconds 0or to one minute at the top centre of the screen.
20. Also, if you are looking at respiration and pulse, right click and check the automatic threshold.
‘Unclick’ it after a few seconds. It allows the scale to be automatically set. In this manner the lines
following pulse rate and respiration will be visible. You may have to do this again if the client changes
their position. (Hold the plethysmograph still while the ‘automatic’ is on!!) You will still find that you
must ‘fine-tune’ the scale at the top of the screen.
21. Occasionally you will want to change the display. Click ‘screen’ then ‘edit’… and you will
be in screen editor. Right click over any instrument you wish to change and a menu will appear. If you
change the channel setting (band-width) on an inhibit or enhance bar graph then you must also rightclick
the 0.00 which you use for % time >C and change its channel input. Remember to also click over
the name above it to change the text of that name. If you change the animation remember to click over
threshold settings in order to change such items as: frames per second, cycle (for repeating like a
bowling game but not like a balance beam) and movement one way or both ways.
22. Do NOT change the name of any instrument even though it looks absurd if you altered the
band-width. (e.g., The name could be SMR (old program) or Enhance2 on the new MT Channel set)
and you just altered the channel setting to problem-solving-beta, Enhance3.) The name of an
instrument could just as well be “Tom, Dick, or Charlie” it is only a name but all the point counters
and other instruments are attached to that original name.
23. If you change a screen then ‘save-as-new” with a new name. If it is for a particular client
put “z” then the client’s name (e.g., z Charles Bowling…) in front of it so it is completely separate
from the original screens on the screen list.
24. If you only want to eliminate a few instruments temporarily for a client then just click view
and click the instruments you wish to hide.
25. For some clients you may be training 2 sites. Prep both sites before you start. This makes it
easy to just move the active electrode between the two sites. (e.g., For a child who is ADHD,
impulsive, over-active and dyslexic you may begin the session at C4 (enhance SMR and the inhibit
dominant slow wave) then for the middle third of the session switch to CP5 (enhance 14-17, inhibit
dominant slow wave while reading) and then for end of the session switch back to C4.
26. Advanced technique: change the speed of the bargraph. Change the points counter using
screen editor link box from 2 seconds to 0.5 seconds. Run screen. When client gets 40 points without
any pause, change the ‘damper’ in ‘edit-edit VC settings’ from 5 to 2.5. When client gets 20 points
without any pause, change ‘damper’ to 1.2 & demand 12 pts then between 0.6 and 1 and get 5pts. 1 st 3
get a blue, then every 5 without a pause gets a white token. (Rewards ‘priced’ in blue. 10 white = 1 blue)..
