Fear memories permanently stored in the prefrontal cortex

The amygdala is one of the oldest organs in the animal kingdom and it has a lot to do with analyzing and processing fear stimulants. But our memories of those stimulants and episodes do not permanently reside in the amygdala or hippocampus. Now, a recent study out of UC Riverside suggests that fear memories are. permanently stored in connections between neurons in the prefrontal cortex or PFC.
