Brain Computer Interface(BCI) with the P300
The P300 Event Related Potential or ERP is an EEG feature commonly used in BCI applications. It has some advantages but also some significant practical…
Applications of Wavelets in EEG
In the previous blogpost, we discussed how wavelets allow us to perform time-frequency characterization of non-stationary signals such as EEG. Here we discuss some applications…
Pitfalls of Filtering the EEG Signal
Filtering of the EEG signal to remove artifacts is a common pre-processing step but introduces temporal distortions in the signal. How do you chose a…
