Coupling training to reduce fear and transplanting embryonic interneurons into the amygdala of mice, researchers were able to reduce fear response, a new study reports.
Imbalanced communication between the hippocampus and amygdala may lead to the inability to distinguish between negative memories that have overlapping features. The findings could provide new treatment options for those with PTSD.
According to researchers, the choice of background music can affect a viewer's attitude towards sharks.
Study provides contrary evidence to existing theory, finding anxiety and fear reflect overlapping neural circuits.
Researchers report medications that boost the effect of naturally produced opioids may be better at reducing anxiety and fear than receptor binding opioids.
Fatty acid amide hydrolase (FAAH) inhibitors, a form of medication that boosts endocannabinoids, may be helpful in the treatment of PTSD. FAAH inhibition can improve the recall of fear extinction memories. The drugs could also help treat stress and other psychological disorders.
Researchers show freezing behavior associated with feat is associated with an internally generated brain state that manifests in sustained 4 Hz oscillatory dynamics in the dorsal medial prefrontal cortex-basolateral amygdala circuits.
