functional mri (fmri)

How does fMRI work in toxicology?

fMRI operates by detecting changes in blood oxygen levels, known as the Blood Oxygen Level Dependent (BOLD) signal. This technique is particularly useful in toxicology for observing how neurotoxins alter brain activity. When a toxin affects brain function, it can lead to changes in the BOLD signal, which fMRI can capture, providing a visual representation of the brain's response to the toxic agent.
