    Notes: Abstract Features of two potassium conductances implicated in the acquisition of conditioned reflexes, the slow calcium dependent conductance (gK+(Ca)) and the fast transient conductance (gK+(A)), were incorporated into a 6 × 6 element artificial neural network. Adaptive algorithms derived from observations of cortical neurons during associative learning changed gK+(A) in proportion to the product of this current and an EPSP-induced second messenger concentration, and changed gK+(Ca) as a function of a spike-induced second messenger concentration. This network concurrently acquired two distinct representations in response to presentation of stimuli: one resembled associative conditioning (defined in terms of its senstivity to forward pairing vs. simultaneous or backward pairing); the other reflected contiguous pairings of stimuli. The acquisition of one representation did not markedly interfere with acquisition of the other. This network may accordingly serve as an example of a self-organizing system which minimizes the postulated inherent cross talk between functionally dissiminar representations (Minsky and Papert 1988).
