Figure 6: Comparison tectopulvinar synaptic terminals to the overall population of synaptic terminals in the Pl and Pcm.

Within animal comparison of projections from SC to PUL labeled with the SV-HRP virus with surrounding terminals in the PUL not labeled with the virus. (a,b,c) Quantitative analysis of the size of presynaptic terminal sizes, comparing unlabeled terminals with SC to PUL terminals (a), unlabeled terminals in the Pcm with contralateral SC to PUL terminals (b), and unlabeled terminals in the Pl with ipsilateral SC to PUL terminals (c). (d,e,f) Quantitative analysis of the size of postsynaptic dendrite sizes, comparing dendrites contacted by unlabeled terminals in PUL with dendrites contacted by SC to PUL terminals (d), dendrites contacted by unlabeled terminals in the Pcm with dendrites contacted by contralateral SC to PUL terminals (e), and dendrites contacted by unlabeled terminals in the Pl with dendrites contacted by ipsilateral SC to PUL terminals (f). A Mann-Whitney U test was utilized in for the comparison in panels (a,d), and a Kruskal-Wallis test was utilized for comparisons in panels (b,c,e,f). *** p< 0.0001. Black bars indicate mean and standard deviation.
