How the stress of fight or flight turns hair white 2020-01-21T05:00:00Z Researchers then measured levels of two hormones found in the rats' fecal samples after driving: corticosterone, which is a marker of stress, and dehydroepiandrosterone, which counteracts stress. Lab rats felt relaxed after driving tiny cars, but not when they were passengers 2019-10-24T04:00:00Z Here’s how The New Scientist describes it: The researchers assessed this by measuring levels of two hormones: corticosterone, a marker of stress, and dehydroepiandrosterone, which counteracts stress. Driving tiny electric cars helped these lab rats feel more relaxed, and we should all learn from them 2019-10-24T04:00:00Z After the trials, researchers collected the rats' faeces to test for the stress hormone corticosterone, as well as for dehydroepiandrosterone, an anti-stress hormone. Rats feel less stressed when driving little cars 2019-10-24T04:00:00Z The researchers found elevated levels of corticosterone, a stress hormone, and higher levels of DNA methylation, a molecular process that indicates changes in which genes are activated. Bird Embryos Vibrate to Warn One Another of Danger before They Hatch 2019-07-22T04:00:00Z This second generation also had lower levels of corticosterone, the mouse equivalent of cortisol, after a stressful spell inside a tight tube. Parents’ emotional trauma may change their children’s biology. Studies in mice show how 2019-07-18T04:00:00Z The ratio of dehydroepiandrosterone to corticosterone increased after they learned how to drive. Lab rats felt relaxed after driving tiny cars, but not when they were passengers 2019-10-24T04:00:00Z The ratio of dehydroepiandrosterone to corticosterone in the rats’ feces increased over the course of their driving training. Driving tiny electric cars helped these lab rats feel more relaxed, and we should all learn from them 2019-10-24T04:00:00Z For the experiment, some mice became stressed when repeatedly restrained, others became so after they were administered the stress hormone corticosterone. Behind the Buzz: How Ketamine Changes the Depressed Patient's Brain 2019-04-12T04:00:00Z Before releasing them back into the wild, Douglas measured the birds' fitness through a stress response hormone called corticosterone—the bird equivalent of cortisol. These Birds Make Their Own Citrus-Scented Cologne 2018-05-25T04:00:00Z Blood tests revealed that levels of corticosterone in birds closest to the gas compressors were far, far lower than normal. Some birds are so stressed by noise pollution it looks like they have PTSD 2018-01-09T05:00:00Z Blood tests revealed that levels of corticosterone in birds closest to the gas compressors were far, far lower than normal. Some birds are so stressed by noise pollution it looks like they have PTSD 2018-01-12T05:00:00Z Specific stress hormones — cortisol in primates, corticosterone in most rodents — are released, some of which surge across the blood–brain barrier. Neurobiology: Rise of resilience : Nature : Nature Publishing Group 2016-03-01T05:00:00Z Daskalakis's group further tested this hypothesis by injecting rats with corticosterone — a naturally occurring glucocorticoid hormone that is released following stress — one hour after trauma exposure. Spread of genes implicated in post-traumatic stress disorder 2014-08-10T04:00:00Z The researchers think that the association between the fear response and the peppermint occurs through elevated blood corticosterone, a hormone that’s equivalent to human cortisol. Fears can be inherited through smell 2014-07-28T04:00:00Z Further experiments, which measured levels of corticosterone, a stress hormone, in the animals’ blood, showed that they were indeed stressed by the mere smell of a man. Pain perception: Sex, writhes and videotape 2014-05-01T15:00:11Z Instead, the stressed-out animals had elevated blood levels of the stress hormone corticosterone. Male Researchers Stress Out Rodents 2014-04-28T19:55:00Z They also looked at corticosterone, a hormone very much involved in the stress response, but couldn’t find any differences. To Calm a Rat with Tickling 2013-04-22T16:15:13.727Z They also have low levels of corticosterone, a stress hormone, in their urine. Stress: The roots of resilience 2012-10-10T17:21:26.287Z The males separated from their mates had much higher levels of corticosterone, a stress chemical, in their blood than did any of the other groups, including voles separated from their brothers. Love Hurts: Brain Chemistry Explains the Pangs of Separation [Excerpt] 2012-09-14T14:45:00.227Z Antidepressants were able to repair the state produced by corticosterone alone. Stress and antidepressants: by their powers combined 2012-05-28T23:15:00.230Z High-fat diet mice showed slightly higher corticosterone, but much higher levels after stress, suggesting that they may be more sensitive to stress than normal mice. High fat diets and depression: a look in mice 2012-05-02T14:45:03.073Z It’s too bad that they didn’t get any differences in plasma corticosterone. To Calm a Rat with Tickling 2013-04-22T16:15:13.727Z Levels of corticosterone, a stress hormone, were markedly lower in the bacteria-fed mice than they were in the control group when both groups were exposed to stressful situations. Bacteria and behaviour: Gut instinct 2011-08-31T17:32:42Z After the forced swim, bacteria-fed mice had about half as much corticosterone, a stress hormone, in their blood as control mice. Friendly Bacteria Cheer Up Anxious Mice 2011-08-30T19:45:00.557Z These effects appear to be independent of the hippocampus, but do depend on the present of corticosterone and fluoxetine. Stress and antidepressants: by their powers combined 2012-05-28T23:15:00.230Z The researchers observed the same effect after they blocked corticosterone receptors in the rats’ brain. Splintered by Stress 2011-08-25T12:45:02.287Z The intervention doesn’t appear to be big, as there aren’t changes in corticosterone, but it’s enough to produce a behavioral effect. To Calm a Rat with Tickling 2013-04-22T16:15:13.727Z A third group of rats received direct injections of corticosterone, which consistently kept the animals’ stress hormones elevated during the experiment. Neurostress: How Stress May Fuel Neurodegenerative Diseases 2011-02-01T12:15:00.243Z The hypothalamus is one of key players in the hypothalamic-pituitary axis, which controls the stress reponse and the secretion of corticosterone. Stress and antidepressants: by their powers combined 2012-05-28T23:15:00.230Z So it looks like the fluoxetine is most effective when combined with corticosterone, or exposure to stress. Stress and antidepressants: by their powers combined 2012-05-28T23:15:00.230Z |
