Picture from the cerebellum

Cerebellum is one of the regions in the brain where neurons are beautifully organized. Here is a picture from the cerebellum of a transgenic mouse expressing ChR2 (ChannelRhodopsin-2) and eYFP (Yellow Fluorescent Protein) in the basket cells of the cerebellum. … Continue reading

Connected topoplot: Visualize networks in your EEG data

In my previous post, I wrote about the Phase Locking Value statistic that can be used to quantify neural synchrony between two electrodes and how it can be a proxy for connectivity. Once you have quantified changes in connectivity using … Continue reading

Phase Locking Value

Phase Locking Value (PLV) is a statistic that can be used to investigate task-induced changes in long range synchronization of neural activity from EEG data. This method is introduced in Lachaux et al., (1999). I have implemented the computation of … Continue reading
