ALK and neurofibromatosis: Adult‐onset Alk inhibition in neurons enhances associative memory in both wild‐type and neurofibromatosis type 1 (NF1) disease model Drosophila (Gouzi, Bouraimi, Roussou, Moressis, & Skoulakis, 2018; Gouzi et al., 2011), and Alk knockout in mice increases adult hippocampal neurogenesis and enhances performance in novel object recognition tasks (Bilsland et al., 2008).
