Topographical maps

Mike sir,
I am new to EEG signals and I am learning.
I bought your book ANTSD and reading. It’s a very good book.
I am unable to analyse topographical graphs. Would you please guide me on how to understand more about topographical maps?

I’m not sure what kind of answer you are looking for. Most people use topographical maps for data visualization and qualitative inspection.

Thank you for the early response.

How can I begin with understanding of topographical maps for EEG signal analysis?

You can read papers that do similar analyses or on a similar topic to yours.
