EEG spectral analysis for sleep-wake cycle

Hi everyone,

I am new to MATlab and not sure how to use it. I have EEG data sampled at 512Hz and stored in text format. Also, I have the same set of data scored for sleep, NREM, and REM and this is stored in excel format.

I am having trouble loading the EEG data into matlab. I am also unsure of how to do FFT spectral analysis for the separate sleep-wake states.

Thank you very much for your help!

Hi jackie I am working on analysis of sleep disorders.I couldnt able to find sleep eeg data and its corresponding sleep score.As you mentioned you have data sllep score in excel format, so please if possible send me that data to me.It would be a great help for my analysis

Hi Jackie, I have some spectral analysis code for loading/analyzing sleep data that we are planning to make available. You can sen me an email to discuss. Best, Dennis

I have received several questions about the spectral analysis source code that I described above.

The spectral analysis code is in the final stages of testing and evaluation by our team. I am in the process of uploading the code to my GITHUB account. More information with examples can be found here: https://github.com/DennisDean/SpectralTrainFig/blob/master/README.md.

The current code is designed to analyze batches of sleep studies.

There are many ways to store data in text and Excel files. We cannot guess, how your files look like, and therefore we cannot suggest a specific solution. The general methods are:

help xlsread
help textscan
help fileread
help importdata

The method to recognize specific patterns of the signals is not a matching topic for this forum, because it has no relation to Matlab. So better ask your professor or instructor and read the corresponding literature.
