Deep sleep restores the medial prefrontal cortex mechanisms that restore emotion. This lowers emotional and physiological reactivity, preventing the escalation of stress and anxiety.
Chronic stress during pregnancy increases neuroinflammation. The immune changes may create circumstances in the brain, which increase susceptibility to postnatal depression.
Researchers report immune cells in the spleen can contribute to chronic anxiety following psychological stress.
Chronic stress alters gene activity in immune cells before they reach the bloodstream. The change leads to an overabundance of inflammation, which is linked to many negative health effects, a new study reports.
Chronic stress which involves the HPA axis may contribute to the development of Alzheimer's disease, researchers report.
Using chemogenetic technology to deactivate a small group of neurons in the claustrum made mice more resilient against chronic stress and reduced anxiety behaviors.
MRI scans show hippocampal shrinkage during periods of chronic stress in rats, a new study reports.
According to new research, stress induced depression may be overcome by inducing neurons which were activated during previous positive experiences.
Researchers discover miR19b modulates behavioral response to chronic stress in mice.
Early life stress alone impairs hippocampal development. Stress, in addition to maternal mistreatment within the first few weeks of life, also hinders amygdala development.
A new study reports that after chronic stress, primed immune cells cause an excessive reaction to a later event.
Findings about how early life social stress affect brain connections in mice may have implications for treating human psychiatric illnesses.
