The nerve cells “have a way of knowing where Brain Hemispheres: A separation of powers a Specific sites in each hemisphere of the brain rol of the opposite side of the they're heading and where to stop to make connections,” said Dr. Roger Morrell, a neurologist at the Neuro- science Research Foundation in Southfield, Mich.

Experiments in rats have shown that the infusion of new brain cells can restore normal levels of a brain chemical called acetylcholine, the supply of which is dras- tically reduced in Alzheim- er’s victims, Morrell said. “I think the experiment, in many people's minds, is cry- ing to be done,” Morrell said in an interview.

For one thing, the most promising source of the brain cells to be transplanted would be the brains of human fetuses, which retain the capacity to divide and grow, unlike mature brain cells.

OFFICE 266-5210 SINGLE PARENTING It's a tough haul By PAUL WOODS When he separated from his wife three years ago, the sudden responsibilities of child care hit Dave Gamache hard. “It was just a zoo!” he recails. “I was trying to get two little guys organized . . . and I had to push and push.” Today, he sits‘in his clean, comfortable living room in Calgary, surrounded by plants and pictures of sons Shaun, nine, and Mark, seven, and there's obvious pride in his voice. It has been a tough haul, as it is for most single parents, but it has been worth it. “There was absolutely never any thought in my mind that I'd give my kids up,” he says. “Never, ever, ever.” Gamache, a former sidewalk installer who has returned to university, is among the steadily growing number of single parents. In 1981, the last year for which statistics are available, there were 714,000 single-parent families in Canada, up 50 per cent from 10 years earlier. Single-parent families represent about 11 per cent of all families in Canada. The -main reason for the incfease?. \“ o Thé'large number of ‘divorces. ¢ OFFERS HELP Fourteen years ago, the One-Parent Families Associa- tion of Canada was established to help such families “take their rightful place in a society based on a traditional two-parent home.” Says Jane Rowan, the association's national treasurer: “You eome out of a marriage: where do you go from here? You can get through the trauma of the breakup, re-establish your life and make new friends.” In 1981, female single parents had average incomes of only $14,000, less than two-thirds of what male lone parents For single mothers under age 35, the average income was only $7,600. Renee Dandurand, a researcher who studied 30 single mothers in Quebec between the ages of 25 and 44, says the economic problems most of them faced were staggering. Many of the fathers didn’t pay child support and the women often had few job skills after being out of the work force for several years. Benjamin Schlesinger, a professor of social work at University of Toronto, says financial problems often force the children of single parents to become more responsible than their peers who have two parents at home. They have to pitch in more around the house or take jobs to help make ends meet. For lone fathers, who represent about one-sixth of all single-parent families, the financial problems usually aren't * as great because they kept working during the marriage. Gamache, whose wife sees their children regularly, says he plays both parental roles with the boys. “I feel I'm the mother and the father,” he says. “I feel I have a lot of the qualities that the mother would have — the softness, the gentleness. “I'm not the stern father type, I never really was. If I didn’t have those other qualities it would have been very difficult to develop them.” Some single parents try to find a surrogate — a relative or friend — to fill the role of the missing parent. As well, there's an increase in joint custody, in which both parents remain active in raising the children. That adjustment is as easier for the children. A common problem for new single parents is separation from friends who are still married. “Friends I had before, when I became single, it wasn't easy for them to invite me over with the kids,” said Gamache. “It was OK when it was the man and wife and the kids, byt, a single and the kids, it just didn't 0 vr ane ppg A Bisse “The -feedback-I1 get from--some one-parent families is that we still live in Canada in a couple-oriented society. I call it the Noah's Ark syndrome.” About one-third of single parents are widowed, while almost 60 per cent are divorced or separated and fewer than 10 per cent never married. Many single parents long for a partner to share the burdens and joys of parenthood. Gamache, who has had a couple of short-lived relationships since his marriage broke up, says the biggest problem he has faced is loneliness. “It’s tough sleeping alone,” he says. “I know I'm a lot happier when I have a woman with me. “I guess. that’s one of my priorities in life, to have a complete family that works.” New Scout program TORONTO (CP) — Scouts Canada has started a new natjonal program to help young children handle the world around them.
