Periaquedactal grey circuits are involved in defence behaviour and fear memory was published yesterday which I predicted six months ago in my blog about amygdala and its distributed circuits in fear memory formation

My Comment

It was my prediction in my blog last year" How do prediction error signals fit together with fear conditioning /extinction? It had been shown that the neurons which are involved in fear acquisition in CeL can send projections directly to the periaqueductal gray (PAG). Does PAG acts as a prediction error center? PAG is involved in transmission in cerebellar and spinal- motor reflex pathways coordinating sensory input and motor output.It might be possible that PAG prepare the animals to react to aversive stimuli and might encode error prediction signal thereby thwarting the need to be alert", . It's a good feeling when your prediction turns correct when it is proved experimentally and published.
