(1) where x h (k) is the discrete Hilbert transform of a signal x(k) [15]. The above convolution effectively introduces a 90∘ phase shift at each frequency component of the signal…

Fig. 1 Typical N100 components from normal control (left) and schizophrenia patient (right) Both the P50 [2, 7, 8, 17–22] and the N100–P200 complex [18, 22–26] exhibit gating effects, even…

Fig. 1 Example of a functional brain network. If a connectivity measure between a pair of channel recordings (the nodes) exceeds the pre-specified threshold then a connection (i.e., an edge)…

(1) Any approach used to solve this kind of problem has to make some assumptions regarding the source signals, the mixing process, or both. The main assumption of ICA is…

(1) where <.> indicates window averaging. The estimated MSC for a given frequency f ranges between 0 (no coupling) and 1 (maximum linear interdependence). 2.3 Phase Locking Value One of…

where a, b ∈ R, a ≠ 0 are the scale and translation parameters, respectively. As a increases the wavelet becomes more narrow and by varying b, the mother wavelet is displaced in time. Thus, the wavelet…

Fig. 1 Incidence of known types of dementias The AD is the most common type of dementia accounting for an estimated 60–80 % of all cases. In the AD, information transfer…

Fig. 1 Flowchart of the analysis pipeline The Influence of Parameters on Results Each part of the analysis pipeline (clustering, labelling, connectivity inference) corresponds to a distinct and autonomous module…

Fig. 1 Schematic illustration of the operational architectonics methodology including steps for EEG segmentation, extraction of segments’ features, and synchronization of segments. Further explanations are provided in the text. RTP—rapid…

Fig. 1 An intracranial multi-contact platinum iridium electrode (Dixi, Beçancon, France) Selecting the brain structures to be explored, and the arrangement and locations of the electrodes, requires a careful analysis…
