... which the signal is lost completely. Moreover, we measured the transcriptional response of the BMP target gene pannier in live embryos and found it to remain activated in dorsal-lateral cells, even after the BMP signal is lost. Our findings may suggest that the BMP pathway activates a memory...

... ( Chabaud et al., 2009 ). The authors report that after training in a group, flies showed stronger memory when also tested in groups than when tested individually. The presence of a trained group during test therefore appeared to improve individuals' memory recall. Interestingly, this facilitating effect...

... a potential role in settlement odour memory or imprinting, expression was evaluated in larvae that were exposed only on the first day post-hatching to Xanthostemon leaves, and not daily. At settlement, odour exposed larvae showed a significant increase in Ap-otx2 transcript abundance in the olfactory area...
