Are there any limitations to using fMRI in toxicology?
While fMRI is a powerful tool, it does have limitations. It primarily measures indirect indicators of neural activity, such as blood flow, rather than direct neuronal firing. This can sometimes make it challenging to interpret the results conclusively. Furthermore, fMRI cannot be used in individuals with certain medical implants, like pacemakers, due to the strong magnetic fields involved. Lastly, the high cost and complexity of fMRI studies can limit their use in toxicology research.
