Relative strength of anterogradely BDA-labeled projections of mouse visual cortex to 31 subcortical targets. Nomenclature is after that in Dong (2008) and Franklin and Paxinos (2008). A–E, Average ± SEM optical density of projections from V1 and the ventral stream areas LM, LI, P, and POR in percentage of the summed density of all subcortical projections labeled from each area. F–J, Projections from the dorsal stream areas AL, RL, AM, PM, and A. Colors indicate functionally broadly similar groups of subcortical targets (Jones, 2007). B–E, insets, Relative strength of anterogradely BDA-labeled projections from ventral stream areas LM, LI, P, and POR to LA, BLA, BMA, CeL, and CeM. Percentage (mean ± SEM) of total optical density of labeled terminal axonal branches (black bars). Values are background-subtracted percentage (mean ± SEM) of optical density relative to the injection site (gray bars). K, Comparison of projection strengths from different visual areas to LA. Two-sample t test: *p <0.001; **p < 0.0001. (–), undetectable; CeL, centrolateral amygdala; CeM, centromedial amygdala).
