Microanatomical density of contacts. A, Number of contacts per dendritic branch versus location for normal juveniles (left) (n = 5479 branches; r = 0.029; p = 0.0315) and prism-adapted owls (right) (n = 3197; r = 0.055; p = 0.0019). The lines are linear regression. B, Mean values for each zone. Significant differences were determined by unpaired Student's t test (Table 1). C, Number of contacts per amount of CaMKII+ dendritic neuropil versus location for normal juveniles (left) (n = 134 image quadrants; r = −0.086; p = 0.3225) and prism-adapted owls (right) (n = 163 image quadrants; r = 0.022; p = 0.7768). The lines are linear regression. D, Mean values for each zone. Significant differences were determined by unpaired Student's t test (Table 1). Error bars indicate SEM.
