Researchers report increased activity in the medial prefrontal cortex is linked to decreased activity in the amygdala.
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.
Researchers discover specific neurons in the brains of rhesus macaque monkeys respond to images of snakes.
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 reduce fear by exposing people to the memory over and over while they slept. The finding could provide a new treatment option for those who suffer from phobias.
Researchers use bio-inspired robots to elicit fear response in zebrafish. They also discover the reaction can be modulated by alcohol.
A new study shows a missing brain protein could lead to abnormal levels of fear.
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.
