The pharmacological effects on the brain will occur widely in whole brain. Therefore,
pharmacological functional MRI (fMRI) is a promising non-invasive tool to investigate
the whole brain activation following pharmacological stimulation. The multimodal fMRI
techniques, which reflect the vascular response (blood oxygenation level dependent fMRI),
neuron/astrocyte activity (diffusion fMRI) and Ca2+ influx in excitatory neurons (manganese
enhanced MRI), enable to observe the neuronal activation in rodent model. In the present
study, the multimodal pharmacological fMRI method in rodents will be introduced.
