M: I'm calling to find out more information about your program. For example, what kind of courses do you offer？
W: Well, first of all, the purpose of our program is to provide language learning opportunities for this area's community, whether a student's goal is to master basic functional language skies, let's say, for his or her job, or to study intensively to enter a US college or university.
M: Okay. I'm calling for a friend who is interested in attending a US university.
W: And that's the kind of, uh, instruction that we provide, from basic communication courses to content-based classes such as computer literacy, intercultural communication, and business English.
M: Great. What are your application deadlines for the next semester？
W: Well, we ask applicants to apply no later than two months before the semester begins. This gives us time to process the application and issue student's I-20.
M: An 1-207
W: Oh, an 1-20 is a form. that indicates that we are giving permission for the student to study in our program, and then the student takes this form. to the US embassy in his or her home country to apply for the F-1 student visa.
M: All right. What is the tuition for a full-time student？
W: It's two thousand thirty dollars.
M: How does one apply？
W: We can send you an application and you can mail it back to us, or you can fill out our application on our website.

The imaging techniques — positron emission tomography scanning and magnetic resonance imaging, known as PET and functional M. R. I. scans — are used prominently in studies of brain activity. The most active brain areas appear to light up on the scans as specific tasks are performed. The two techniques do not measure nerve-cell activity directly; they measure the extra flow of blood that surges to the most active brain areas.
Researchers at the Weizmann Institute of Science in Rehovot, Israel, have monitored these changes in blood flow in anesthetized cats by removing parts of the skull and observing how the nerve cells in activated regions fuel their activities by rapidly removing oxygen from nearby red blood cells.
This rapid uptake of oxygen, made evident by visible changes in the color of the red cells, proves that early oxygen transfer gives these neurons the energy to do their work, the researchers said.
They also found that subtle changes in blood flow began significantly earlier than was detected by PET and functional M. R. I. scans, which lack sufficient resolution and do not form. their images quickly enough to follow such rapid changes. Dr. Amiram Grinvald published the findings in the Journal Science.
"The initial event is very localized and will be missed if you don't look for it soon enough and use the highest possible resolution," Dr. Grinvald said. "Now people are beginning to use our results with other imaging methods."
Working on the exposed brain lets researchers follow electrical activity and the accompanying blood flow in greater detail than is possible by using indirect imaging methods that track neural activity through the skull. However, opportunities for open-skull studies of humans are limited to some kinds of neurosurgery, and researchers must mostly rely on PET and functional M. R. I. images for studies linking behavior. with specific brain activity.
By directly observing exposed cat brains and in similar work with a few human cases, Dr. Grinvald and his associates have been able to observe the first evidence of electrical activity and other changes in brain cells after a light has been seen or a limb moved.
The newest research showed that it took three seconds or more after an event for the flow of blood to increase to an area of the brain dealing with a stimulus. That is the blood-flow increase usually pictured in brain-function studies with PET or functional M. R. I techniques, the Israeli researchers said. However, the initial reaction observed in the Weizmann research by directly imaging the exposed brain — the direct transfer of oxygen from blood cells to neurons — occurred in the first-tenth of a second and was lost to conventional imaging, they said.
The later increase in blood flow to the area, Dr. Grinvald said, was obviously an attempt by the body to supply more oxygen for brain activity. But the increase in blood was so abundant that it covered an area much larger than the region directly involved in the activity being studied, masking some of the subtle changes, he said.
The body's reaction, the researchers said in the paper, was like "watering the entire garden for the sake of one thirsty flower."
Dr. Kamil Ugurbil, said that the Israeli research provided clues that allowed the use of functional M. R. I. scans to picture earlier events in the activity of brain cells.
"Dr. Grinvald's observations are very important, and they have significant implications for functional imaging with high resolution," Dr. Ugurbil said in an interview. "We have actual
A．those changes are subtle and masked by some reactions
B．subtle changes in blood flow began earlier
C．the imaging techniques are out of place
D．the flow of blood to increase to an area of the brain is slow
