1.   A second development was the discovery that adult brains continue to produce new cells, overturning conventional wisdom that brain cells are not replenished.

2.   A quarter-century ago, Pasko Rakic, a leading neuroanatomist at Yale University, declared that no new neurons were formed in the adult brain.

3.   But Goldman is thought to be the first to generate neurons from adult human brains and grow them in a laboratory.

4.   But in recent years, scientists are also discovering that adult brains, as well, can undergo surprising changes in response to experience.

5.   Could an adult brain really come up with Spanking Head?

6.   If the adult brain is amenable to change, maladaptive circuits formed in infancy or childhood may be alterable by psychotherapy or other methods.

7.   It caps a series of findings that refute the longstanding view that no new cells are formed in the adult brain.

8.   Neural stem cells should not exist, because the adult brain was long thought not to renew itself.

9.   Others became incorporated into the cache of stem cells around the ventricles, ready for use in supplying and repairing the adult brain.

10.   Researchers in other states have found limited success using fetal cells to restore the adult brain cells that produce dopamine, a chemical that controls movement and coordi nation.
