Researchers have identified a new neural mechanism that contributes to long term stress and PTSD. The study reports the mechanism is mediated by brain fluid in areas associated with stress response.
Researchers pin memory loss to neuroinflammation and the immune system following sustained stress.
New research into the brain cells of roundworms may help scientists better understand how some humans are better able to cope with stress.
Gene expression is influence by gamers' degree of social connectedness to others, researchers report. For those with online gaming addiction, the gene expression can lead to chronic stress.
A new study reports that serotonin promotes the consolidation of traumatic memories following stress events. Additionally, SSRI medications which are commonly prescribed for PTSD may make the condition worse by enhancing the effects of serotonin.
A new study reveals a link between a vulnerability to depression and noradrenergic neurons.
In mice, social stress can increase risk factors for cardiovascular disease and shorten life span, researchers report.
Researchers discover miR19b modulates behavioral response to chronic stress in mice.
Findings about how early life social stress affect brain connections in mice may have implications for treating human psychiatric illnesses.
A new study identifies a novel neural network regulating feeding and mood in response to chronic stress. Inhibiting the POMC to ventral tegmental area circuit increases body weight and food intake while reducing depressive symptoms in mouse models.
Findings may lead to better diagnosis and treatment for disorders related to chronic stress.
Rats susceptible to anhedonia have more serotonin neurons in the ventral dorsal raphe nucleus. However, activating neurons in the central amygdala reduced the serotonin signaling and lowered the effects of social stress.
