fifty-sentence test set 97% of the time, given 40 minutes of training data per participant. Future research Experts are unsure of how far thought identification can expand, but Marcel Just believed in 2014 that in 3–5 years there will be a machine that is able to read complex thoughts such as 'I hate so-and-so'. Donald Marks, founder and chief science officer of MMT, is working on playing back thoughts individuals have after they have already been recorded. Researchers at the University of California Berkeley have already been successful in forming, erasing, and reactivating memories in rats. Marks says they are working on applying the same techniques to humans. This discovery could be monumental for war veterans who suffer from PTSD. Further research is also being done in analyzing brain activity during video games to detect criminals, neuromarketing, and using brain scans in government security checks. In popular culture Episode Black Hole of American medical drama House, which aired on March 15, 2010, featured an experimental "cognitive imaging" device that supposedly allowed seeing into a patient's subconscious mind. The patient was first put in a preparation phase of six hours while watching video clips, attached to a neuroimaging device looking like electroencephalography or Functional near-infrared spectroscopy, to train the neuroimaging classifier. Then the patient was put under twilight anesthesia, and the same device was used to try to infer what was going through the patient's mind. The fictional episode somewhat anticipated the study by Nishimoto et al. published the following year, in which fMRI was used instead. In the movie Dumb and Dumber To, one scene shows a brain reader. In the Henry Danger episode, "Dream Busters," a machine showed Henry's dream.
