Abstract EN
Juvenile barn owls readily adapt to prismatic spectacles, whereas adult owls living under standard aviary conditions do not.
We previously demonstrated that phosphorylation of the cyclic-AMP response element-binding protein (CREB) provides a readout of the instructive signals that guide plasticity in juveniles.
Here we investigated phosphorylation of calcium/calmodulin-dependent protein kinase II (pCaMKII) in both juveniles and adults.
In contrast to CREB, we found no differences in pCaMKII expression between prism-wearing and control juveniles within the external nucleus of the inferior colliculus (ICX), the major site of plasticity.
For prism-wearing adults that hunted live mice and are capable of adaptation, expression of pCaMKII was increased relative to prism-wearing adults that fed passively on dead mice and are not capable of adaptation.
This effect did not bear the hallmarks of instructive information: it was not localized to rostral ICX and did not exhibit a patchy distribution reflecting discrete bimodal stimuli.
These data are consistent with a role for CaMKII as a permissive rather than an instructive factor.
In addition, the paucity of pCaMKII expression in passively fed adults suggests that the permissive default setting is “off” in adults.
