MEART
is a geographically detached artist. Its "brain" consists of dissociated
rat neurons grown in culture. It is at home and growing in Atlanta.
The body,
though, - a robot arm with a drawing facility attached to it, is in Perth,
Australia. The brain and body interact through the internet (TCP/IP)
in real
time.
These
neurons are cultured over 60 electrodes fitted on a glass substrate. The electrodes
pick up 60 channels of activity from the neurons.
The data received from the
neural activity is processed both in Atlanta & Perth
to control in real time the robotic (drawing) arm. The feedback loop is closed
by stimulating the neurons (again, 60 electrodes, 60 different areas in the
culture) when various events in the gallery space occur. We had MEART "draw
portraits". Each morning we captured an image of a gallery visitor.
Then we degraded it to 60 Pixels and fed that into the 60
electrodes to stimulate the neurons.
Once
we sent stimulation to the neurons we recorded the neural activity and used
this data to move the drawing arm. The reading/stimulations occurred every
1-5 sec.
We were interested to see if any emergent or “creative” behavior
will occur, or trace any change in the pattern of behavior of the neurons that
occurs as a result of the stimulations. The drawings that we got were very
interesting, mainly their differences.
The combined elements of unpredictability
and “temperament” with
the ability to learn and adapt, create an artistic entity that is both dependent,
and independent, from its creator and its creator’s intentions.
