Hi all! I'm a neuroscience major and I'm planning my senior honors thesis right now. I'm interested in magnetoreception (ability to sense magnetic fields), and I'd like to do something involving the effect of a strong magnetic field on humans' or animals' navigational abilities and/or behavior. Basically, I'd love to use humans ... but I'm not sure if I can safely expose people to a >1 Tesla B field. I know that really strong magnetic fields can disrupt electrical firing in the brain ... or is that only magnetic pulses? Anyway, does anyone know how strong of a field I can use? Or if I need to already be an MD to do it? Also, if I can't use humans, what would be a good animal to test? I can't find a comprehensive list of which animals have already been shown to have magnetoreception and which animals are yet to be tested. I'm thinking lower mammals would be great. Anybody have any suggestions for me? Thanks!
