No need to get fancy - you're not braiding a
little girl's hair!  Braiding electrods means
you just sort of twist the wires
together.  The idea is to get them as close
together as possible so that all the wires
pick up the same amount of any stray
magnetic signals that are in the room.
    Some types of magnetic signals may be
from the power lines in the walls, or from
large equipment with motors.  When the
signal is picked up evenly at all electrodes,
the ABR system will be able to cancel it
out.  Braiding increases the chances that
the signal will be even at the different
electrodes.
