[Neuroscience] Neuronal activity in the brain

[Fijoy George]

Hi all,

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
Fijoy
