Researchers discover an enhanced expression of the CRF-1 gene the ovum of rats exposed to stress prior to conceiving. Additionally, enhanced expression of the gene was noted in newborn rats whose mothers were exposed to stress.
A new study finds exercise reorganized the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function.
According to new research, the 9/11 terror attacks may have caused 1 million former smokers to take up and maintain the habit once again.
Researchers have shown stress on preadolesecent and adult male mice induced an epigenetic mark in their sperm which reprogrammed their offspring's HPA axis, a region the the brain which governs stress response.
According to a new study, ovulating women may be more vulnerable to some psychological side effects associated with stressful experiences. The results suggest a monthly window of opportunity that could potentially be targeted in efforts to prevent common mental health problems developing in women.
A new study is to investigate whether music affects the health of cancer patients by soothing them and making them less anxious. Depending on the outcomes, future research could hone in on how much anxiety levels decreased after music therapy and how reduced anxiety affects a patient's recovery time, complications and willingness to comply with treatment.
By watching individual neurons at work, a group of psychologists at the University of Wisconsin-Madison has revealed just how stress can addle the mind, as well as how neurons in the brain's prefrontal cortex help remember information in the first place.
Researchers identified a potential medical treatment for cognitive effects of stress-related disorders, including post-traumatic stress disorder (PTSD). The study, conducted in a PTSD mouse model, shows that an experimental drug called S107, one of a new class of small-molecule compounds called Rycals, prevented learning and memory deficits associated with stress-related disorders.
Scientists have laid bare a novel molecular mechanism responsible for the major depression symptom, anhedonia, the loss of the ability to experience pleasure. The brain circuit involved in this newly elucidated pathway is largely identical between rodents and humans, upping the odds that the findings point toward new therapies for depression and other disorders. Additionally, opinion leaders hailed the study’s inventive methodology, saying it may offer a much sounder approach to testing new antidepressants.
