title: Functional spectroscopy to no-gradient fMRI.
abstract: The article embraces two periods in the history of fMRI starting with our early work on functional spectroscopy leading to the detection of the ominous initial dip and our recent development of gradient-less imaging based on the principles of MR-encephalography (MREG). In addition to presenting examples from these two periods the article tries to convey the spirit and inspiration behind these developments.
