Hippocampal levels of ChAT, PKA, phospho-PKA and phospho-CaMKIIα but not CaMKIIα positively correlate with spatial learning skills in rats

- Rate of spatial learning positively correlate with hippocampal levels of PKA and ChAT but not CaMKIIα.
- Spatial learning skills positively correlate with activation of hippocampal PKA and CaMKIIα.
- Activation of hippocampal kinases is more reliable learning index than their constitutive expression.
