*U* WITH ADVANCED ELECTROOPTICS TECHNOLOGY, SOVIET ENGINEERS HAVE
DEVELOPED A DEVICE THAT MIMICS THE HUMAN BRAIN IN THE WAY THAT THE
BRAIN PROCESSES INFORMATION. LIKE THE REAL THING, THE SOVIET ANALOG
IS A MULTILEVEL NETWORK OF NERVE CELLS. THE NATURAL BRAIN, A
PARALLEL PROCESSOR, CONSISTS OF ABOUT 10EXP11 NEURONS OR NERVE
CELLS, BUT THE GREATER VOLUME IS MADE UP OF ABOUT 10EXP14
INTERCONNECTIONS AMONG THESE NEURONS. THE SOVIET ANALOG IS
STRUCTURED SIMPLISTICALLY THE SAME WAY BUT USES A THRESHOLD FILTER,
PHOTOCELL, LASER, AND HOLOGRAM OPERATING IN SERIES AS THE BASIC
ELEMENT. INTERCONNECTIONS ARE MADE OPTICALLY.
*U* THE SOVIET NEURON WORKS IN 'THIS WAY: WHEN AN INPUT SIGNAL (S) IN
THE FORM OF LIGHT IRRADIATES'THE PHOTOCELL, ITS OUTPUT DRIVES THE
LASER, WHICH PRODUCES AN OUTPUT THAT IS SPLIT AND MODULATED BY THE
HOLOGRAM. AFTER BEING SPLIT, 'THE LASER ACTIVATES THE PHOTOCELLS AT
THE NEXT LEVEL. INFORMATION STORED ON THE HOLOGRAMS CONSTITUTES THE
PROGRAM AND DETERMINES THE INTERCONNECTIONS FOR TIE OPTICAL BRAIN.
THE THRESHOLD FILTER SETS THE MINIMUM LIGHT LEVEL REQUIRED TO
ACTIVATE THE PHOTOCELL.
*U* IN THE REAL BRAIN, THESE INTERCONNECTIONS CAN NUMBER IN THE TENS
OF THOUSANDS PER NEURONS. STATE-OF-THE-ART MICROELECTRONICS COULD
NOT BE USED TO SIMULATE THIS STRUCTURE AND STAY WITHIN A REASONABLE
SIZE. IN ADDITION TO BEING 'LIMITED BY PACKING DENSITY OF THE
CONNECTIONS BETWEEN NEURONS, MICROELECTRONIC CIRCUITS SUFFER FROM
THE POTENTIAL FOR INFORMATION' LEAKAGE FROM CROSS TALK (UNDESIRED
TRANSFER OF SIGNALS). INTERCONNECTIONS BY OPTICAL RADIATION ARE NOT
BOUND BY EITHER RESTRICTION.
