Passage: Researchers recently found that there is an area called thalamic pillow deep in the brain. It's like a receptionist for information. It is responsible for classifying and sorting out the information of external stimuli, and focuses people's attention on the most important information about behavior and survival. The researchers point out that the discovery is expected to lead to new treatments for disorders caused by lack of attention, such as attention deficit hyperactivity disorder, schizophrenia and so on.
Question: Which of the followings is assumed by the above argument?
A. A.Some schizophrenias are not caused by lack of attention.
B. B.Visual information is only transmitted through the neural network obtained from the visual cortex.
C. C.Researchers have developed a new technique that can directly track the communication between the nerve plexus in the visual cortex and the thalamic occipital area.
D. D.The brain cannot process too much information in detail at the same time, and only selectively focuses its attention on the things that are most relevant to behavior.
