[Neuroscience] Neuronal activity in the brain

Would someone be able to help me with the following question?
When we look at the neuronal activation areas in Functional Magnetic
Resonance Images obtained from various experiments, we see that in each
area, the activity is most intense at the center and slowly declines towards
the boundary. Now, suppose we were to actually measure the neuronal currents
in the activation areas. Will the current amplitudes follow the same
pattern? That is, will the current amplitudes be highest near the center of
the area, and smoothly decline toward the boundary?
Thank you very much
