“Another shock for brain imaging research - the signal isn’t always linked to neuronal activity”(BPS Research Digest),
Yevgeniy Sirotin and Aniruddha Das have reported that blood flow changes in the brain - the signal measured by brain scanners - are not always linked to changes in neuronal activity. Experts have known for some time that the relationship between blood flow and neuronal activity might be rather complicated but this is the first time that such an extreme mismatch has been demonstrated.これは，興味深い…
