If the two brains can work at the same time, you have this as well

Compartmentalized Mind 50 points/level
Your mental coordination gives
you, in effect, more than one mind.
Each mind – or “compartment” – functions
independently and at full capability.
Your compartments are identical,
but hypnotism, magic, psionics, and
the like affect them separately (e.g., one
compartment could be hypnotized
without affecting any of the others).
This advantage does not allow your
body to perform more than one task. A
normal character may select one
maneuver on his turn in combat. This
may be physical or mental. Each level
of Compartmentalized Mind adds
one extra mental maneuver to
this allotment. For instance, Compartmentalized
Mind 1 would let you perform
one mental maneuver and one
physical maneuver (e.g., Concentrate
on a spell and Attack) or two mental
maneuvers (e.g., Concentrate on two
spells), but never more than one physical
maneuver – for that, see Extra
Attack (p. 53).
If one compartment is under external
influence, roll a Quick Contest of
Will to see whether it gains control of
the body. The compartment currently
in control of the body rolls at +1.
Battling compartments may attempt to
use mental powers on each other. Treat
them as completely separate minds for
this purpose, each with your IQ, Will,
and mental abilities (such as Mind
Shield).
Two variations on this advantage
are available for vehicles built as
characters:
Controls: Each level buys one set of
controls. Controls let an operator perform
his own physical or mental
maneuvers using your abilities (e.g.,
Innate Attack or Radar), as per the
rules for vehicular combat (see p. 467).
The operator directs all actions of an IQ
0 vehicle with this advantage. Physical
limits still apply; for instance, a vehicle
can make no more attacks than it has
ready weapons. Resolve conflicts
between operators by rolling a Quick
Contest of vehicle operation skill. 25
points/level.
Dedicated Controls: As Controls, but
each set of controls handles a specific
task; e.g., “tail gunner.” The person
manning them can’t operate anything
else. 10 points/level.
