Researchers report increased activity in the medial prefrontal cortex is linked to decreased activity in the amygdala.
Using neuroimaging technology to measure the size and connectivity of the amygdala allows researchers to predict the degree of anxiety a young child experiences in daily life, a new study reports.
Using mouse models, researchers report that exposure therapy remodels an inhibitory junction in the amygdala. The findings could improve understanding of how exposure therapy could suppress fear responses and help develop new treatment methods for those with anxiety disorders.
The “hunger hormone” ghrelin, when released during chronic stress, makes the brain more vulnerable to traumatic events. Researchers suggest this could predispose people to PTSD.
Researchers discover a gene essential for memory extinction. The finding could lead to new treatments for PTSD.
Researchers erase drug associated memories in mice and rats without affecting other memories.
Researchers have discovered a communication pathway between the amygdala and ventral hippocampus which appears to control anxiety. The findings could help pinpoint better targets for anti-anxiety treatments.
New research into the brain cells of roundworms may help scientists better understand how some humans are better able to cope with stress.
Researchers discover a low dose of psilocybin erased conditioned fear responses in mice. They suggest the agent could be a potential treatment for PTSD and related conditions.
Researchers have discovered how fear can increase or decrease the ability to discriminate among sounds, depending upon context. The study provides insight into distorted sound perception with victims of PTSD.
