Abstract(in English) | Spike triggered average (STA) and phase response curve characterize response properties of single neurons. A recent theoretical study proposed a method to estimate the phase response curve by means of linear regression with Fourier basis functions. In this study, we propose a method to estimate the STA by means of sparse linear regression with Fourier and polynomial basis functions. By sparse estimation with L1 regularization, we extract substantial basis functions for the STA in the proposed method. We show using simulated data that the proposed method achieves more accurate estimation of the STA than simple trial average used in conventional method. |
