Summary

THE ARTICLE REPORTS A COMPLETELY NEW WAY OF INVESTIGATING NEURON NETWORKS. CERTAIN DISORDERED MAGNETIC MATERIALS (SPIN GLASSES) HAVE PHASE TRANSITIONS OF A VITREOUS TYPE, LINKED TO SPIN INTERACTIONS WHICH ARE ALEATORILY FERRO OR ANTIFERROMAGNETIC. PHYSICIANS AND BIOLOGISTS OBSERVED THAT, IN SPITE OF A SYMMETRY DIFFERENCE IN THE INTERACTION, THE POTENTIAL LAYOUTS OF A SPIN SYSTEM IN A HORIZONTAL PLANE GIVE AN < ENERGY LANDSCAPE > VERY SIMILAR TO THE ONE OF A NEURON NETWORK FUNCTIONING AS MEMORY. THEN, THEY MADE AN ANALOGY BETWEEN SPINS AND NEURONS, WITH VERY FRUITFUL RESULTS. DIVERSIFIED ASPECTS AND CONCLUSIONS OF THIS INTERPRETATION. REACTION OF NEUROBIOLOGISTS, PSYCHOLOGISTS AND COMPUTER ENGINEERS.
