Abstract
The interest in BOLD contrast based phMRI is likely to increase in the coming years, but detecting a direct modulation of regional brain activity by drugs presents a challenging problem. Based on in-vivo MRI and simulations we highlight some of the issues in detecting especially small BOLD signals in rat phMRI experiments.
