I was surprised by Senator O'Toole's contribution and thought he was somewhat emotive on this issue. Most of his contribution was devoted to the question of the possible good effects that might arise. The report of a select committee of the House of Lords clearly cautioned against raising people's hopes in that regard. The main research done on Parkinson's disease, both embryonic stem cell research and adult stem cell research, has shown that the most positive results have come from adult stem cell research. People may disagree with that, but this is the information I have. If this is the case, we should not raise people's hopes, which would cloud the issue. The House of Lords select committee said there was no indication that this therapy would ensue.
