That gave encouragement to others that rigorous experimental work addressing brain-behavior relations was possible in infants.

It also fundamentally altered the scientific understanding of PFC early in development; clearly it was not silent as accepted wisdom had held. Even though PFC is very immature early in life and takes a very long time to develop, it can already subserve elementary versions of the highest cognitive functions during the first year of life.

Diamond went on to facilitate many of the earliest collaborations between developmental and cognitive scientists, on the one hand, and neuroscientists on the other. She provided the first demonstration of a visual deficit in treated PKU children which changed international guidelines for the age of treatment onset.

No one had ever done anything like that.

Again, the answer lay in integrating two fields. Neuropharmacologists studying the mesocortical dopamine system in rats had shown that if there is only a modest reduction in the dopamine precursor, tyrosine, PFC is selectively affected. To test that hypothesis, Diamond again turned to work in both humans and animals.

They were thereby able to demonstrate the mechanism causing the deficits that had so confounded those working in inborn errors of metabolism, and to demonstrate that the deficits could be prevented by stricter dietary restrictons.

Midway through, Diamond learned that the dopamine system in the retina shares the same unusual properties as those that cause PFC to be sensitive to reductions in available tyrosine too small to affect other brain regions. To be consistent, she had to predict that retinal function would also be adversely impacted in children treated for PKU, so she ventured into vision science to investigate that together with pediatric optometrist, Dr.

Two superficially unrelated behavioral effects a selective cognitive deficit and a selective visual deficit were found to have same underlying cause. An animal model of early-treated PKU.

One discrepancy troubled Diamond, however. The visual deficits were not. By the time her team studied contrast sensitivity, they knew what range of Phe levels produced a deficit and so only sampled from within that range.

Having a truncated range of current Phe levels could easily have accounted for the failure to find a relation between contrast sensitivity and current Phe levels.

However, a child born with PKU is usually not started on treatment for the disorder until about 10 days of age. The visual system is maturing very rapidly during the days and weeks right after birth.

Perhaps the excessively high levels of Phe reaching the brain during those first days after birth impairs the visual system.

To test that hypothesis Diamond brought in pairs of siblings, both of whom had PKU, as well as children from the general population.

The importance of the sibling pairs was that while PKU in the first child born with the disorder is not detected until the heel prick test after birth, amniocentesis is performed for all later-born children and so it is known if any of those children have PKU before birth.

The first-born children started dietary treatment on average at 11 days of age, while the later-born children started the diet on average at 3 days of age.

They found consistently that the first PKU sibling in a family had poorer contrast sensitivity at low levels of contrast than his or her younger PKU sibling and than children from the general population.

The children whose brains were exposed to massive levels of Phe for the first 10 days of life showed no deficits in visual acuity or in determining form from texture, but they were impaired in contrast sensitivity at very low levels of contrast and in determining form from motion. These deficits were evident over 10 years later when we tested the children.Deborah Lee “Debbie” Blakeman, 68, dually residing in Sturgis, SD, and Apache Junction, AZ, journeyed to be with the Lord, her brothers, and her parents on Wednesday, November 7, , at Rapid City Regional Hospital with her immediate family and siblings by her side.

Few institutions approach the richness of The Museum of Modern Art’s holdings in painting, sculpture, drawing, prints. Here is the Internet's finest collection of historic museums and other public spaces, all of whom would welcome your visit.

The Frick Collection in New York is home to some of the world-renowned paintings by the equally outstanding European artists. The museum also have an extensive collection of sculptures, th century French furniture and other artifacts from the same era .

We are also looking for volunteers to help with the website. We currently have a huge backlog of submissions which need to be edited for display online, if you have a good standard of written English, an interest in the two World Wars and a little time to spare online we would appreciate your help.
