Introduction
and Background Information on NeuroSpec.
NeuroSpec consists of a
number of MATLAB functions for performing multivariate Fourier analysis of time
series and/or point process (spike train or event) data, and plotting the
results. The software consists of a number of MATLAB functions for performing
time and frequency domain analyses of time series and/or point process data, and
plotting the results. NeuroSpec 2.0 implements
a multivariate spectral analysis, it includes routines for two channel auto
spectral and cross spectral (coherence, phase, cumulant density) analysis, and a
number of extensions including comparison of spectra, a stationarity test for
spectra, comparison of coherence, system identification (gain, phase and impulse
response), and pooled analysis (pooled spectra, pooled coherence, pooled phase,
pooled cumulant density). Pooled analysis incorporates extended difference of spectra and extended difference
of coherence tests. It was designed primarily for use on Neural data, but is suited
to a wide range of stationary stochastic (random) signals.
Theoretical and practical aspects of the analysis are described in the
following articles:
