Corticosterone is a 21 carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands.
Study reveals that gut microbiota from individuals with social anxiety disorder (SAD) can induce social fear behaviors in mice, suggesting a causal role of gut microbes in modulating behaviors relevant to SAD.
A study by researchers at EPFL shows why only a subset of individuals exposed to trauma develop posttraumatic stress disorder (PTSD).
Bristol University scientists reveal that night shift work disrupts the body's circadian rhythm, altering appetite-regulating hormones and leading to weight gain. The study, providing insights into metabolic health, may aid in developing treatments for eating disorders and obesity.
Childhood neglect and/or abuse can induce extreme stress that significantly changes neural networks and functions during growth. This can lead to mental illnesses, including depression and schizophrenia, but the exact mechanism and means to control it were yet to be discovered.
Regular physical exercise, such as resistance training, can prevent Alzheimer's disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer's patients.
The World Health Organization recently indicated that aspartame will likely be declared a “possible carcinogen to humans.”
Study uncovered mechanisms by which psychological stress affects bowel inflammation.
Mice with a defected human gene responsible for a rare genetic disease, called congenital adrenal hyperplasia, have been developed for the first time.
Can an individual's social status have an impact on their level of stress? Researchers at Tulane University put that question to the test and believe that social rank, particularly in females, does indeed affect the stress response.
A new study published in the journal Frontiers in Medicine reviewed recent literature on the link between gut microbiota, the brain, and neurological disorders.
Reproductive health experts consider hormonal contraceptives good choices for adolescents because they're safe and highly effective at preventing pregnancy, but one aspect of their effect on the teenage body remains a mystery – whether and how they modify the developing brain.
The evidence for the interconnection between emotional states and intestinal conditions has grown recently. These findings have led researchers to speculate about the association between the brain and the gut – the "gut-brain axis."
A new research paper was published in Aging ("Aging (Albany NY)" by Medline/PubMed, "Aging-US" by Web of Science) Volume 14, Issue 13, entitled, "Age-related neuroendocrine, cognitive, and behavioral co-morbidities are promoted by HIV-1 Tat expression in male mice."
A new study explores how acute stressors affected mice in terms of their immune responses in specific regions of the brain.
Fire can put a tropical songbird's sex life on ice. Following habitat-destroying wildfires in Australia, researchers found that many male red-backed fairywrens failed to molt into their red-and-black ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers.
Birds play an underrecognized role in spreading tickborne disease due to their capacity for long-distance travel and tendency to split their time in different parts of the world - patterns that are shifting due to climate change.
Female rats that inhaled vaporized cannabis daily for a month developed a blunted physiological response to stress, according to a new study by Washington State University researchers.
This work has investigated the long-term consequences of stress experienced at this critical period of life in rodents, in collaboration with the Behavioural Genetics laboratory at the Brain and Mind Institute of the Federal Polytechnic School of Lausanne (Switzerland), led by the Spanish researcher Carmen Sandi.
New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function.
A new study has shown that the compound resveratrol found in red wine demonstrates stress relieving effects in anxiety and depression. This could be due to resveratrol’s ability to control an enzyme in the brain that is liked to stress say the researchers from the University at Buffalo in collaboration with Xuzhou Medical University in China.
