Connectomics of the octopus 'fan-out fan-in’ learning network reveals that the intermediate layer uses approximately 22×10⁶ excitatory interneurons, each can store a single sensory input, while approximately 400×10³ integrating inhibitory interneurons adjust the network output level.

Neurogenic progenitor cells surrounding the eye placode generate neurons that migrate over long distances to the developing octopus brain.

Single-cell transcriptomics correlated with in situ gene expression analysis provide an overview of the diversity and molecular features of cell types in the squid Loligo vulgaris.

Hypothetical battles between animals can be used to interest the general public in biology.
