EEG signal processing I have an EEG data set downloaded from physionet. I want to play that data into a brain monitoring device like for example BIS monitor or Narcotrend or any other similar brain monitoring device.I use Matlab GUI to visualize the data. Can I send it from a Matlab GUI to any one of the brain monitoring devices with a suitable hardware  in between.Any ideas please I am new to EEG signals.
I'll assume that you want to do online monitoring.

You can always store the coming data from the GUI in a vector in MATLABA.
Then you can run simple code to plot them.

This also depends on the type of measurements you have. If the set is capable on detecting power ranges as well you should have the following readings:

High Alpha, Low Alpha, High Beta, Low Beta, High Gamma, Low Gamma, Delta, Theta, Attention, and Meditation.
