This yeаr scientists used оptоgenetics tо try аnd understаnd social hierarchy in mice. To determine social hierarchy, they trained mice to walk through a tube in one direction. Then they put two mice on either end of the tube; the mice tried to walk through the tube in opposite directions. When the mice met in the middle of the tube they pushed each other; both were trying to get through the tube and make it to the other side. Ultimately, one mouse abandoned its attempt, turned around and retreated out of the tube on the same side that it had entered. The mouse that retreated was the “loser”, and the mouse that successfully walked through the tube from one side to the other was the ”winner”. Control animals walked through the tube without encountering another mouse. Below you can see that winners had c-fos expression in the PAG region of the brain, while losers had c-fos expression in the aBLA region of the brain. Control animals didn’t have much c-fos expression in either brain area. Researchers activated or inhibited PAG or aBLA neurons using optogenetics in only one of the mice in the tube. To do this, they injected a virus carrying an opsin transgene downstream of a pan-neuronal promoter into the dmPFC region of the brain. dmPFC neurons are excitatory and project to both PAG and aBLA brain regions. Below you can see what happened to mouse retreats when scientists specifically controlled dmPFC neurons that excite PAG neurons by positioning the fiber optic canula so that that delivered light to the PAG region (A, C), AND when they positioned it to deliver light to the aBLA region (B,D). Based on what happened to retreats in A and B, can you predict what happened to retreats in C and D? (Note, this is actually what happened.) Which of the bar graphs below do you predict for panel C?
