"Synaptic mechanisms for associative learning in the cerebellar nuclei" by Broersen et al. 2023 https://www.nature.com/articles/s41467-023-43227-w
"optogenetic stimulation of mossy fiber afferents to the anterior interposed nucleus (AIP) can substitute for a conditioned stimulus and is sufficient to elicit conditioned responses (CRs) that are adaptively well-timed."
The role of the cerebellar nuclei (CN) during associative learning remains debated. Here, the authors show that well-timed conditioned responses can result from stimulating CN inputs, and that learning coincides with structural and synaptic activity changes in vivo.
No brainer? #jellyfish are able of associative learning. They learn to avoid obstacles based on visual stimuli, even though they have only rudimentary nervous systems and no central brain.

A trio of biologists, two with the University of Fribourg, in Switzerland, the third with Universitat de Barcelona, in Spain, has found that a type of Cnidaria is capable of associative learning. Gaelle Botton-Amiot, Simon Sprecher and Pedro Martinez published their study in the Proceedings of the National Academy of Sciences.
