Event-Related Functional MRI Study on Central Representation of Acute Muscle Pain Induced by Electrical Stimulation
2002
NeuroImage
Preserved Fulltext
We used eventrelated functional magnetic resonance imaging (MRI) and the high sensitivity of the 3-T MRI scanner to study the central processing of acute muscle pain induced by intramuscular electrostimulation ...
The aims of the study were to establish the pain matrix for muscle pain in the full head volume and, further, to explore the possibility of a functional segregation to nonpainful and painful stimuli within ...
