Part Four: EEG ERP plot and hacking EEGLAB plots

In the last few posts we covered specific topics related to making figures. In the first, I referenced a nice paper that provides 10 rules for making nice figures and I spent some time outlining a few that I think are particularly valuable to consider. In the second, I showed several approaches to plot the time series data. In the third, I used time-frequency analysis of EEG data (event related synchronization/desynchronization–ERD/S) as a way to highlight the impact of color and scaling on the representation of the data. In this post I am going to get a bit more specific to EEG analysis/plotting in that we will be using a function from the EEGLAB toolbox to plot event related data on a projection of the scalp. However, one of the main take-aways is that we can start with pre-built funtions and then make improvements once we decipher out the figure output.
