COMP9844 - NeuraLab Experiment 1
This lab is designed to introduce students to advanced techniques
in Inductive Neural Network Technology. It utilises the start-of-the-art
equipment in CSE's NeuraLab®.
It is wise to read through the instructions well in advance
of your actual lab.
Class members should report to the NeuraLab at 11.30pm on the day of
their timetabled lab class, and form teams of three. (NeuraLab is
located in the K17 sub-basement, which has a direct connection to the
lightning conductor on the roof of K17, for power enhancement.)
The lab attendant will direct your
attention to the animal and human ethics consent forms, which you should
complete as rapidly as possible, no need to read them closely, as there is
a lot of work to fit into the lab period!
Each group of three should decide among themselves who is to be the
Subject, who will be the Operator, and who will be the Observer.
The Observer for each team will be located in the insulated re-enforced
glass booth on one side of the NeuraLab proper. It is important at this
stage to note down whether the Subject is a postgraduate student or a
senior undergraduate.
Experimental Procedure
-
The Subjects must each choose a brush turkey (Alectura lathami) from
the animal house in the adjacent
room. Choose carefully, as you may have a prolonged and intimate
relationship with the animal should any carelessness on your team's part
result in a malfunction in the NeuraLab software. Write your name on the
turkey leg-band and fasten the band on your turkey's legs, to avoid any
unplanned mix-ups. You are advised to choose a turkey of the same
gender as yourself in order to simplify re-orientation in a later stage in the
experiment. (The female can easily be identified, as it has much smaller
yellow wattles than the breeding male bird in the illustration below. Of
course, non-breeding males have smaller wattles, too.)
-
If you are an Observer, you should now enter the observation room, and don the
goggles and headphones provided. Spend at least ten minutes familiarising
yourself with the monitors and controls, which provide you with facilities
to record the phenomena you are about to observe, not just in audio and video,
but also in terms of neural traces from the 148,000 leads used in the NeuralLab
hardware. You may need to act quickly in the event of a sudden development
(let alone a malfunction!)
-
The Subjects should, after transferring their chosen turkey to the custody
of their Operator, be seated in the human subject chair in their transfer
station area. Each Operator
should, after securing the turkey in the animal restraint opposite their
Subject, fasten the restraints on the Subject in the human-sized chair.
This should be done firmly and most carefully, for reasons that will become
very clear as the experiment proceeds. At this stage, each Operator should
double-check to confirm that the legband on the their turkey has the name
of his/her Subject on it.
- Next, each Operator should take the two helmets
with attached cables and electrodes and place them over the heads of
their turkey and their (human) Subject. The turkey-sized one is, of course,
used for the turkey, and the larger one for the Subject. Trying to use them
the other way around is not funny, and may result in serious
academic misconduct penalties. Automatic systems (details of which cannot
be revealed because of a confidentiality agreement in a NeuraLab
R&D contract with the US Department of Defense) now cut
in and implant harmless nano-electrodes into the scalp of the Subject.
These nano-electrodes painlessly infiltrate the cranial sutures and faultlessly
connect to neurons of the neocortex, concentrating on key regions of
the parietal cortex and the DLPFC (dorso-lateral pre-frontal cortex).
-
Each Operator should now sit down at his/her control console and
spend at least ten minutes familiarising him/herself with the facilities
provided. It is possible that in the case of incomplete success of the
automated process, you may need to adjust the parameters and possibly
activate semi-automated insertion of supplementary nano-electrodes.
-
When the Operator is confident that s/he has mastered the controls,
s/he should signal to the Observer that all is in readiness, and wait
for a confirmation from the Observer that s/he is ready to record
the experimental data. On receiving this confirmation, identify the
large red lever. Grasp the lever and push up firmly, to move the
lever from the OFF position to the ON position. Although the helmets
provide reasonable sound insulation, some Operators find that
it is comforting to wear hearing protection during this step - you will
find industrial grade (60dB) hearing protection at each transfer station.
-
The Observer must ensure that the recording systems are
activated at least 10 seconds in advance of the transfer - not too
much more because of the massive bandwidth consumed.
-
The essence and consciousness of Subject and turkey should
now have been swapped between the two. It is wise to maintain the
restraints during this phase of the experiment, following an
incident in which a careless Operator allowed a Subject
to escape into the scrub behind the lower campus carpark.
-
To confirm that the transfer has been performed successfully, take
some of the turkey food (consisting of seeds, fruits, grain, insects
and earthworms) in the packets at each transfer station and
offer it to the Subject. If s/he accepts and consumes the food, it is
safe to say that transfer has taken place, at least in one direction. Low
grunts and moans, clucking, and utterance of a sound resembling Gock!,
are also diagnostic of the transfer having taken place in this
direction.
Next, present the turkey with a simple C-programming task, and the second
screen and keyboard provided (the keyboard that looks as though it
has been pecked). Automated software is provided to check the solution
created by the turkey: anything higher than 46% is regarded as a pass
for undergraduates[a] provided that they have a good WAM; for a
postgraduate Subject, however, 50% must be achieved.
-
In case of failure, it will be necessary to consult the troubleshooting
guide, accessible on-line from the Operator's console. This will explain
how to adjust the parameters and activate the secondary nano-electrodes.
Following the instructions closely, modify the parameters as necessary
and then, after confirming Observer readiness, reach down and pull the
blue lever with the red F (for Fix) in one smooth movement.
-
Repeat the testing and if necessary adjust the parameters and pull the
blue lever until success is achieved.
-
When all experimental measurements and tests have been satisfactorily
completed, you will need to reverse the transformation/exchange.
This should in no circumstances be attempted before testing
reveals complete and successful transfer has occurred, as otherwise
it may be difficult to unravel the personalities of Subject and turkey
- in which case the Subject's parents/family may end up spending a
fortune on bird-seed and earthworms.
- The final step of this experiment, in which the turkey and Subject
personalities are restored to their original configuration, is complex,
and is described in the Reversing the turkey-human
transformation web page.
Acknowledgment
The course coordinator would like to thank Richard Buckland[1]
for his inestimable
assistance in the design and implementation of the NeuraLab systems.
Footnote
- Undergraduates who are potential graduands with no other
failures in the current term and a good WAM
should also be considered for a pass,
in accordance with
UNSW policy. Hmm, or maybe a supp (mwahahaha).
My thanks to Thurston Dang[2] for pointing this out.
