EEG data from Emotiv

Hey ! I have a data table of 14 channels as columns from the 14 channel Emotiv EEG acquisition system. Sampling frequency 128 hz. How do I analyse this data after importing it into the Matlab editor?

I am unsure which parameters or what kind of features I can study from this data. Please do explain the steps.

The table looks like this with 3200 rows in total. How do I plot Voltage vs Time plot ?

Answer 1

First you need to construct a vector representing the time values associated with your data:

t = (1:3200)/128;

Then you can plot the voltages against the time:

figure;

plot(t, data)
