Real life dream catcher ! Scientists have designed the worlds first inception-style dream reader that can decode your dreams with reasonable accuracy.In the Leonardo DiCaprio starrer Inception,people manipulate others dreams and steal their sleeping thoughts.
In a new study,neuroscientist Yukiyasu Kamitani and colleagues at the Advanced Telecommunications Research Institute International in Kyoto,Japan monitored three young men as they tried to get some sleep inside an fMRI scanner while the machine monitored their brain activity.
Researchers also monitored each volunteers brain activity with EEG electrodes,and when they saw an EEG signature indicative of dreaming,they woke him up to ask what hed been dreaming about.
Researchers call it hypnagogic imagery, the dream-like state that occurs as people fall asleep.They woke up each subject at least 200 times over the course of several days to build up a database of dream reports,website wired.com reported.
Kamitani and colleagues then developed a visual imagery decoder based on machine learning algorithms.They trained the decoder to classify patterns of brain activity recorded from the same three men while they were awake and watching a video montage of hundreds of images selected from several on-line databases.After the decoder for each person had been trained,the researchers could input a pattern of brain activity and have the decoder predict which image was most likely to have produced that pattern of brain activity.
Kamitanis team went beyond previous work in feeding the decoder patterns of brain activity collected while the subjects were dreaming.This enabled them to correctly identify objects the men had seen in their dreams,they report in journal Science.They could identify the type of object a subject had seen,it could predict that a man had dreamt about a car,not that hed been cruising around in a Maserati.
