Characterization of the Stages of Creative Writing With Mobile EEG Using Generalized Partial Directed Coherence [PDF]
Frontiers in Human Neuroscience, 2020 Two stages of the creative writing process were characterized through mobile scalp electroencephalography (EEG) in a 16-week creative writing workshop. Portable dry EEG systems (four channels: TP09, AF07, AF08, TP10) with synchronized head acceleration ...

Partial Directed Coherence and the Vector Autoregressive Modelling Myth and a Caveat. [PDF]
Front Netw Physiol, 2022 Here we dispel the lingering myth that Partial Directed Coherence is a Vector Autoregressive (VAR) Modelling dependent concept. In fact, our examples show that it is spectral factorization that lies at its heart, for which VAR modelling is a mere, albeit very efficient and convenient, device.

Using Partial Directed Coherence to Study Alpha-Band Effective Brain Networks during a Visuospatial Attention Task [PDF]
Behavioural Neurology, 2019 Previous studies have shown that the neural mechanisms underlying visual spatial attention rely on top-down control information from the frontal and parietal cortexes, which ultimately amplifies sensory processing of stimulus occurred at the attended ...

Frequency domain connectivity identification: an application of partial directed coherence in fMRI. [PDF]
Hum Brain Mapp, 2009 AbstractFunctional magnetic resonance imaging (fMRI) has become an important tool in Neuroscience due to its noninvasive and high spatial resolution properties compared to other methods like PET or EEG. Characterization of the neural connectivity has been the aim of several cognitive researches, as the interactions among cortical areas lie at the heart
