Second-order Wiener kernels can be decomposed into excitatory and suppressive components via singular-value decomposition.

Evidence

So computed, h 2 is an m -by-m matrix with units of spikes·s‑1 ·Pa‑2 (Recio-Spinoso et al. 2005 ). We used singular-value decomposition to parse h 2 into excitatory (h 2ε ) and suppressive (h 2σ ) sub-kernels (Lewis et al. 2002a , 2002b ; Lewis and van Dijk 2004 ; Rust et al. 2005 ; Sneary and Lewis 2007 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3837
