You were able by looking at the scan to be able to tell whether or not her memory was likely to be real.
The man she testified against was eventually found guilty of murder.
Marksevich based the test on research in which university students watched movies and were tested on their memories.
He found that when students record things in the film they actually saw, a specific part of the brain was activated.
But when they genuinely thought they recorded something but were wrong, a different part lit up.
It's pioneering work.
But it doesn't convince Geraint Rees, leading neuroimager at UCL.
Marksevich himself is well aware of the shortcomings of scanning, especially when used on a single individual.
So he uses it only amongst a battery of other techniques to assess memory.
Even he thinks it's simply not reliable enough to use on most witnesses, at least yet.
But the big step forward in the modern form of brain scanning, its ability to image brain processes in real time, leads him to make the bold claim that fMRI technology will be used in courts within the next decade.
If you really have individuals who want to deceive, they will deceive these technologists in the same way as they deceived old lie detection technologists.
Old lie detection technologists are almost never admissible in the courts.
Nick Rose is one of Britain's most cited sociologists, and he's an expert on how science impacts society.
He's not that worried about using brain scans in courts, because he thinks judges will just dismiss unreliable neuroscience techniques.
But Rose thinks the impact of brain science on criminal justice may lie elsewhere.
And at that point, the evidence, the arguments are not tested in the way in which they are tested in the courtroom.
For some neuroscientists, it's not so much the courts as wider society that should be taking notice of new insights.
Kent Keel of the University of New Mexico is an evangelist for brain science.
So committed is he to understanding the brains of murderers and other criminals that he drives his own mobile brain scanner into high-security prisons.
