I am analyzing the performance of the sLORETA under different scenarios.
It performed very well with one source even when increasing the Noise, However, With two different sources activate at the same time, (even with low noise) it is performing very poorly. Does anyone know what is the reason for that? Based on the other papers/journals that I have read, sLORETA should perform pretty good in estimating the sources (With only drawback of having the low resolution). Why is it missing a source in this case? is it a computational problem?
Current Density Map Can estimate properly but Sloreta CANT
Here is the specification of my experiment as well as attachments:
- I have used BESA SIMULATOR to simulate the data
- Both Sources are Exactly Same: This Means (SAME STARTING AND ENDING POINT, SAME SHAPE, SAME FREQUENCY, SAME AMPLITUDE, ) ONLY different locations
- Noise is 0.21 MicroVolt (Around 15-20dB SNR im guessing)
- No Pre-Processing , Only setting channel location + Average Referencing
