Connectionism without the connections

Biological systems which inspire connectionist architecture are based upon axonal point to point connections. As we attempt to engineer ever larger analogues of these neural networks we are forced to multiplex neural signals over time shared paths. This can alter the timing of signal arrival which is critical in oscillatory networks and leads to the bandwidth-synchrony dilemma. This paper further describes the problem, especially for analog VLSI systems, and approaches under consideration for the solution
