[Principles of functional magnetic resonance tomography].
The basic principles of brain activation studies by MRI and functional spectroscopy are presented. The paper introduces the underlying mechanisms, followed by a discussion of the possibilities and limitations of current and new measuring techniques. Functional MRI has already proven to be a useful tool in neurocognitive research. Initial clinical applications have especially been demonstrated in neurosurgical operation planning.
