Wavelet Time-Frequency Analysis

Hi,
I am doing LFP analysis using complex wavelets as being taught in the course using the same code but when I compare my result with other papers, it’s not quite well.
This is my result:

And this is a sample paper which they also used wavelet but their result are much better than mine:
Impaired In Vivo Gamma Oscillations in the Medial Entorhinal Cortex of Knock-in Alzheimer Model
(sorry I wasn’t able to put more than two pictures in my post)

My question is that is there any way to get a better result?

Hi Morteza. It looks like you have some nice oscillations at around 30 Hz. You could try increasing the number of cycles of the wavelet, and also changing the color scaling to actually see the activity.
