Researchers find protein that makes long-term memory possible
...remember things for more than a day--sometimes for many
years. Scientists have suspected that BDNF played a role in memory, but had not known whether it exerted its effect directly, or in combination with other substances. The first clue came in 1996. Then, Dr. Lu and his colleagues reported in N...

of the genes as he can. "It's very difficult work, expensive and time-consuming," he said. "We will be focusing on several chromosomal regions, several specific genes, and continue to collaborate with people doing animal research."...
