The following (short) technical report is ftp-able from the 
Salk Institute. The file is called bell.noisy.ps.Z, it is 0.65 Mbytes 
compressed, 1.9 Mbytes uncompressed, and 10 pages long (4 figures).

It describes work presented at the Computation and Neural Systems 1994
meeting (CNS '94), but which was late for inclusion in the Proceedings.

                            ABSTRACT

Five related factors are identified which enable single compartment
Hodgkin-Huxley model neurons to convert random synaptic input into 
irregular spike trains similar to those seen in {\em in vivo} cortical 
recordings. We suggest that cortical neurons may operate in a narrow 
parameter regime where synaptic and intrinsic conductances are balanced 
to reflect, through spike timing, detailed correlations in the inputs.
