Note

Examining different aspects of learning and memory, Claridge-Chang et al. (2009) and Krashes et al. (2009) converge on the same set of neurons in the protocerebral posterior lateral 1 (PPL1) cluster in Drosophila melanogaster. The different roles attributed to PPL1 neurons demonstrate heterogeneity of function in small neuronal subsets of the Drosophila brain.
