[EX Q]: Article: Scientists think it will be possible to record people's dreams and then interpret them, according to a new report. They claim to have developed a system which allows them to record higher level brain activity. Dr Moran Cerf told the journal Nature: "We would like to read people's dreams." Previously the only way to access people's dreams is for psychologists to ask about them after the event and try to interpret them. Dr Cerf hopes to eventually compare people's memories of their dreams with an electronic visualization of their brain activity. He told the BBC: "There's no clear answer as to why humans dream. And one of the questions we would like to answer is when do we actually create this dream?" The scientist believes his latest research shows that certain neurons or individual brain cells are linked with specific objects or concepts. He found that a particular neuron lit up when a volunteer thought about Marilyn Monroe. If a database was built up identifying various neurons with concepts, objects and people it would allow them to "read the subject's minds", according to Dr Cerf. However, Dr Roderick Oner, a clinical psychologist and dream expert, said that this kind of visualisation would be of limited help when it came to interpreting the "complex dream narrative". In addition to get a detailed picture of individual neurons subjects had to have electrodes implanted deep in the brain using surgery. The Nature researchers used data from patients who had electrodes implanted to monitor and treat them for brain seizures . However, Dr Cerf said he hoped that it would be possible at a later stage to monitor people without invasive surgery. He said it would be "wonderful" to be able to read the minds of _ patients who are unable to communicate.
Answer: by linking certain neurons with specific objects or concept

[EX Q]: Article: A new research has uncovered that culture is a determining factor when people interpret facial emotions .The study reveals that in cultures where emotional control is the standard,such as Japan,the focus is placed on the eyes to interpret emotions. Whereas in cultures where emotion is openly expressed,such as the United States,the focus is on the mouth to interpret emotions. "These findings go against the popular theory that the facial expressions of basic emotions can be universally recognized," said University of Alberta researcher Dr.Takahiko Masuda." A person's culture plays a very strong role in determining how he will read emotions and needs to be considered when interpreting the facial expressions." These cultural differences are even noticeable in computer emoticons ,which are used to convey a writer's emotions by email and text message. The Japanese emotions for happiness and sadness vary in terms of how the eyes are drawn ,while the American emotions vary with the direction of the mouth. In the United States the emoticons:)and:) show a happy face,whereas the emoticons:(and:(show a sad face. However,the Japanese tend to use the symbol ('') to indicate a happy face,and (;;) to indicate a sad face. "We think it is quite interesting and appropriate that culture tends to mask its emotions. The Japanese would focus on a person's eyes when detecting his or her emotions,as eyes tend to be quite subtle ,"said Masuda. "In the United States,where an open emotion is quite common,it makes sense to focus on the mouth,which is the most expressive feature on a person's face."
Answer: culture is a key to interpreting facial emotions
