Finding humor in life can help to improve happiness and reduce stress.
Researchers have traced neural pathways that connect the brain to the gut. The findings provide a biological mechanism that explains how stress can cause ulcers.
Using a small molecule drug that reduces activity of the brain's stress circuitry significantly reduces Alzheimer's neuropathology and prevents the onsite of cognitive impairment in mouse models of the disease, a new study reports.
Oral contraceptive use is associated with blunted stress response and brain activity differences during working memory tasks in women who started using birth control during puberty. Early adulthood exposure to oral contraceptives was linked to significant structural changes in brain areas associated with memory and emotional processing.
Researchers discover receptors for stress activated hormones are localized in oral taste cells responsible for detecting sweet, umami and bitter tastes.
Using three different training models, researchers report mental training, mindfulness and meditation can induce structural brain plasticity and reduce social stress.
Social isolation caused by housing animals alone increases stress and epilepsy in rodent models. The effects of social isolation may negatively impact the results of preclinical drug trials that use these animals.
Many people claim meditation helps to relieve their daily stresses. A new study provides objective evidence which supports the claims. Researchers found cortisol levels from hair samples decreased by 25% following a six-month meditation training program.
Researchers have identified a gene that appears to be implicated in depression in both animal and human models of the disorder. The gene, Slc6a15 can either amplify or reduce stress, depending on its level of activity.
Researchers say stress may directly impact female fertility and ovarian reserve. Exposing female rats to scream sounds, researchers noted a decrease in estrogen and Anti-Mullerian hormone levels. Stress also reduced the number and quality of eggs, resulting in smaller litters. The findings shed light on the role stress may play on female reproduction.
When under stress, adenine methylation increases up to four times, a new Emory study reports.
People who experience fewer stressors in daily life report better emotional stability, moods, and overall health. However, those who are less stressed score worse on cognitive tests than those who experience daily stressors. Those who are stress-free are also less likely to give emotional support or experience positive things happening throughout the day.
