Hunting Increases Phosphorylation of Calcium/Calmodulin-Dependent Protein Kinase Type II in Adult Barn Owls

Figure 5

pCaMKII regulation is uniform across the ICX. (a) Representative section after high magnification imaging. Photobleaching of the 63x confocal image fields confirms their location within ICX. Fields 1–5 are located in rostral ICX, which represents frontal auditory space and is subject to optical displacement. Fields 6–8 are located in caudal ICX, which represents peripheral auditory space and is not subject to optical displacement. Rostrocaudal location was assessed according to the criterion in Nichols and DeBello, 2008. (b) Mean pCaMKII intensities for R (rostral) and C (caudal) image fields in all four experimental groups. The differences are small, inconsistent across groups, and not significant (minimum value, Ctrl R versus C, ). (c) Field deviation is the percentage change in mean signal intensity from one image field to its nearest neighbor. Neither comparison was significant: Ctrl versus prism, ; passive versus active, .
