Asymptotics for Linear Processes
A method of deriving asymptotics for linear processes is introduced which uses an explicit algebraic decomposition of the linear filter. The method leads to substantial simplifications in theExpand

Dynamic Analysis of Neural Encoding by Point Process Adaptive Filtering
We use the Bayes' rule Chapman-Kolmogorov paradigm with a linear state equation and point process observation models to derive adaptive filters appropriate for estimation from neural spike trains. Expand

Motion and Ballistocardiogram Artifact Removal for Interleaved Recording of EEG and EPs during MRI
This paper introduces a method for motion artifact cancellation using piezoelectric motion sensor information to estimate the mapping between motion sensor and EEG space, subtracting the motion-related noise from the raw EEG signal. Expand

Dynamic Analyses of Information Encoding in Neural Ensembles
We present a general recursive filter decoding algorithm based on a point process model of individual neuron spiking activity and a linear stochastic state-space model of the biological signal. Expand
