Tin offers high conductivity at an affordable price.
9mm
flat electrodes and a 1.5mm (.059) DIN safety plug.
The
special designed safety plugs offer more space between safety plugs even at
narrowly placed sockets and a better fit also with wider (worn out) sockets at
some head boxes
IMA
electrodes with Teflon wiring have 144 silver strands per lead.
IMA
electrodes with silicone coated wiring have 7 silver ribbons combined with
Kevlar for strength, dipped in silicone coating.
Each
type : 48” = 1 ohm resistance out of 4,000 ohm from scalp.
Care:
Do
not soak in water (creates corrosive brine).
Wipe
with alcohol after each use.
For
heavy discoloration or build up on silver electrodes use toothpaste (not gel),
comet or ajax, wipe gently and rinse with warm water.
For
gold plated electrodes use alcohol or toothpaste (not gel), be very gentle,
rinse only - do not soak. Scratched plating is the most common cause of failure
for gold electrodes.
Take
care not to crimp the wires or pull at wires from the ends, this is the most
common reason of failure for all electrode wiring.
Mono Polar / Bi Polar Set = 2 Ear Clips (black/blue) and 2 Flat Leads (green/yellow) (colors may vary depending on stock)
Operating Principle:
A bipolar configuration consists of placing both of the active sensors on the brain sites generating EEG activity with the clips on a relatively neutral point such as the earlobe. With this configuration the sensors will detect EEG activity from both sites and across an area between the sites. To date, the majority of clinical EEG feedback work has been with bipolar configurations.
Response Characteristics:
Clinical research indicates that the behavioral correlates of EEG activity are dependent, to some extent, upon the region(s) of the brain being monitored, e.g., variances in subjective state associated with specific EEG patterns between the right and left hemispheres and between the frontal, parietal and occipital lobes.
Note: Additional parts may be required to connect a second set of electrodes to the amplifier for two-channel training.
Thought Technology Amplifiers: Use with DIN Adapter (CBL-09001) and EEG FlexPro (CBL-9305) or EEG-Z sensor (CBL-9305Z).
BrainMaster: Use withInput Cable (EEG) 48" for Atlantis and Discovery 24 (CBL-BM381-006)
J&J Technology Amplifiers, other than SPectrum add TP-60 Electrode Adapter.
