title: Deconvolution of compound action potentials and nonlinear features of the PST histogram.
abstract: Deconvolution of the compound action potential (CAP) with a uniform unit response (UR) results in the compound PST histogram (CPST). After a logarithmic transformation of the CPST, a second deconvolution of the obtained transformed PST histogram (TPST) with an intensity-dependent norm PST histogram (NPST) may be feasible to determine the excitation pattern (E), reflecting the contributions from the individual nerve fibres. The presented model investigations show that, in spite of nonlinearities, a normalized PST histogram can be assumed. Application to recorded CAPs yields excitation patterns almost as predicted by the model.
