Porthole and Stormcloud: Tools for Visualisation of Spatiotemporal M/EEG Statistics

Abstract

Electro- and magneto-encephalography are functional neuroimaging modalities characterised by their ability to quantify dynamic spatiotemporal activity within the brain. However, the visualisation techniques used to illustrate these effects are currently limited to single- or multi-channel time series plots, topographic scalp maps and orthographic cross-sections of the spatiotemporal data structure. Whilst these methods each have their own strength and weaknesses, they are only able to show a subset of the data and are suboptimal at articulating one or both of the space-time components. Here, we propose Porthole and Stormcloud, a set of data visualisation tools which can automatically generat..
