    On Neural Connectivity Estimation Problems
    (2015) BACCALA, Luiz A.; SAMESHIMA, Koichi
    After briefly recapping and reframing the problem of neural connectivity and its implications for today's brain mapping efforts, we argue that supplementing/replacing traditional conservative correlation based analysis methods requires active user understanding of the aims and limitations of the newly proposed multivariate analysis frameworks before the new methods can gain general acceptance and full profit can be made from the expanded descriptive opportunities they offer.

    Partial Directed Coherence Statistical Performance Characteristics in Frequency Domain
    (2015) SAMESHIMA, Koichi; TAKAHASHI, Daniel Yasumasa; BACCALA, Luiz Antonio
    In this work we show the asymptotic behavior of information partial directed coherence estimator via the Monte Carlo simulation of a particular toy model taken from the literature. We show that the control of false positive rate tends to the chosen significance level if detection decision is made at specific frequency values.
