That has left psychologists pondering the methods that these people use to rationalize the conflict. A study published in the Journal of Applied Social Psychology takes a look at one of these methods, which the authors term "scientific impotence"the decision that science can't actually address the issue at hand properly. It finds evidence that not only supports the scientific impotence model, but suggests that it could be contagious. Once a subject has decided that a given topic is off limits to science, they tend to start applying the same logic to other issues. The paper is worth reading for the introduction alone, which sets up the problem of science acceptance within the context of persuasive arguments and belief systems. There's a significant amount of literature that considers how people resist persuasion, and at least seven different strategies have been identified. But the author, Towson University's Geoffrey Munro, attempts to carve out an exceptional place for scientific information. "Belief-contradicting scientific information may elicit different resistance processes than belief-contradicting information of a nonscientific nature," he argues.

New Therapies for Impotent Men Possible: Experiments on Mice Show
He says they now understand that the nerve impulses that originate from the brain and from physical stimulation are sustained by a cascade of chemicals that are generated during the erection following the initial release of nitric oxide. The basic biology of erections at the rodent level is the same as in humans, he says. The key finding is that after the initial release of nitric oxide, a biochemical process called phosphorylation takes place to continue its release and sustain the erection. In a landmark study published in the journal Science in 1992, http://www.mhcaustralia.com.au/treatment-programs/ Burnett and his Johns Hopkins co-author, Solomon S. Snyder, M.D., professor of neuroscience (who is also an author on the current study), showed for the first time that nitric oxide is produced in penile tissue. Their study demonstrated the key role of nitric oxide as a neurotransmitter responsible for triggering erections. Now, 20 years later, we know that nitric oxide is not just a blip here or there, but instead it initiates a cyclic system that continues to produce waves of the neurotransmitter from the penile nerves, says Burnett.

The Future of Scientific Discovery: 75th Anniversary Closing Panel Discussion
Peter McPherson, neuroscientist, Montreal Neurological Institute and Hospital The Montreal Neurological Institute and Hospital is a world-renowned integrated facility of excellence in research and patient care, with eight floors consolidating both. Among its 11 research units that are closely integrated with clinical activities, the Neuro has internationally recognized strengths in epilepsy, brain imaging, cognitive neuroscience, neuroimmunology, complex neural systems and neuromuscular disease. A new expansion is being added to the North Wing to enhance the capacity of the McConnell Brain Imaging Centre, the Experimental Therapeutics Program and outpatient facilities. The Neuro was the first research facility in Canada to own magnetic resonance imaging (MRI) and computerized tomography scanners. Now, it has positron emission tomography, functional MRI, and magnetoencephalography machines that will help determine the physiologic events within the brain that affect behaviour, thought and emotion. The McConnell Brain Imaging Centre, founded in 1984 by Dr. William Feindel, houses this state-of-the-art equipment and ranks among the top two or three in the world. Supporting over 125 professors, researchers and biomedical engineers, the Centre serves the McGill community of hospitals with links to other institutions across North America. In addition to an innovative Post-Polio Clinic, the Multiple Sclerosis (MS) Clinic is one of the largest MS research clinics in the country with high-impact neurologists on staff. A separate entity on the same floor, the Polyclinic offers treatments for different conditions each day, ranging from Parkinsons disease to epilepsy, pain, and amyotrophic lateral sclerosis.
