New Research Reveals How Fear Get Stuck in Brains

The study adds to our understanding of the processes behind anxiety-related disorders and reveals commonalities between anxiety and alcohol dependence.in Sweden that increases the strength with which fear memories are stored in the brain The research, conducted in rats, was published in the scientific journal. It provides new insights into the processes behind anxiety-related disorders and identified shared mechanisms of anxiety and alcohol dependence.

Some brain regions are especially important for processing fear-related memories. When threatened, the amygdala is activated and collaborates with parts of the frontal brain lobes, known as the “prefrontal cortex,” which are critical for emotion regulation. In order for new memories to last, they must be stabilized and preserved as long-term memories. This process is known as “consolidation”. The researchers in the current study have investigated the effects of reduced levels of PRDM2 on the way fear memories are processed.
