WebExposure to even mild, uncontrollable stress causes a rapid loss of PFC function. Feedforward Ca2+-PKC and cAMP-PKA signaling rapidly opens K+ channels to disconnect dlPFC networks and reduce neuronal firing, i.e. Going To Hell In A Handbasket. However, there are mechanisms that inhibit these stress reactions and restore PFC top-down control. WebSep 25, 2015 · This study and ref. 19 above were the first to show that stress exposure impairs PFC function in animals and that it is caused by high levels of stress-induced catecholamine release in the PFC.
