scientists at the brown hall for institute for molecular biology in applied to college in peace and are using the insects in their research they're feeding the beatles the pesticide paraquat which attacks their nervous system and alters their behavior. and i was on the commission because feed them substances that trigger symptoms similar to parkinson's disease then we mix different plant extracts into their food to see if any of them can alleviate the symptoms these are some that the researchers then cut test strips for the insects to climb up this is what the beatles do naturally as they explore their environment the induced parkinson's symptoms slow their movements and make them unsteady. the scientists are looking to see which group of beetles climbs the highest in one minute. the theory goes that the strongest climbers have ingested a substance that best mitigates the parkinson's symptoms. the differences are clear to see some peoples are vigorous climbers while others move hardly at all the best response comes from beetles that ingested drugs that are already used to treat parkinso
