Fascinating study published in Science that used an experimental paradigm and fMRI to investigate the neural networks underlying the control and suppression of memory retrieval in survivors of the 2015 Paris terrorist attacks, some of whom developed PTSD and some who did not. The findings implicate certain brain regions (nice infographic available) and suggest that intrusions are related to maladaptive control of the memory. The authors discuss the implications for development of PTSD and potential avenues for treatment. Well worth listening to the podcast (in right column of webpage) which starts at 12.27 minutes.
