I have recently processed a whole bunch of ASSR data. Once I have the spectrograms how do I compare groups statistically because it is 2D data? In particular I am interested to know if there 20Hz and 40Hz ASSR differ between two treatment groups.
Hi Brandon, I am expecting differences in phase locking factor and induced power. I would like to compare between groups the 20Hz and 40Hz results. I have calculated all the values, but I am unsure which values I compare such as do I average time epoch power for 20Hz and 40Hz and compare these values. or do something else entirely. Thanks for your help.
I have found out how to do the analysis. I will need to average across an epoch with a specific frequency band to get the average power. From this number I can perform standard statistics. For example I can average the power from 19-21Hz over 100-200ms to get a measure of induced spectral perturbation.
