TY - JOUR ID - 988747 AU - Havlíček, Martin - Jan, Jiri - Brázdil, Milan - Calhoun, Vince D PY - 2011 TI - DECONVOLUTION OF NEURONAL SIGNAL FROM HEMODYNAMIC RESPONSE PB - IEEE CY - NEW YORK SN - 9781457705397 KW - cubature KW - Kalman KW - fMRI KW - deconvolution KW - smoother N2 - In this paper we describe a deconvolution technique for obtaining an approximation of the neuronal signal from an observed hemodynamic response in fMRI data. Our approach, based on the Rauch-Tung-Striebel smoother for square-root cubature Kalman filter, enables us to accurately infer the hidden states, parameters, and the input of the dynamic system. Using a series of simulations we show in this paper that we are able to move beyond the limitation of a poorly sampled observation signal and estimate the true structure of underlying neuronal signal with significantly improved temporal resolution.
