It is a fundamental phenomenon in responding to new stimuli, which have rarely occurred in the same way in the past. Although it is a well documented phenomenon, its molecular and cellular basis are not clear. Previous studies in our laboratory showed that the genetic manipulation of the phosphodiesterase 4, Dunce, controls the level of generalization in contextual memory and olfactory conditioning. These data suggested that PKA signaling might be involved in learning generalization. Although the role of PKA in learning and memory has been determined, its role in generalization is unclear.

\nIn order to determine the role of PKA in generalization we suppress PKA activity by a PKAC1 RNAi in neurons in Drosophila and examine memory and generalization. To assess memory, we used the contextual learning paradigm, where memory is tested in three different contexts, the original context, a similar or a different one.
\nPreliminary results suggested that the suppression of PKA impaired memory retrieval induced by the original context, without affecting the memory retrieved by a similar context. These results suggest that PKA function is not necessary for the generalization process and other molecular mechanisms might be involved.<\/p>\n","protected":false},"excerpt":{"rendered":"
