Using biological neural network for machine learning

What’s the essential properties of the structure of biological neural network? Are they built for optimized learning? Then can we use their structure to train an effective Artificial neural network or Machine learning in general?

Rodriguez2019optimal proposes that biological neural networks may be organized around the Optimal modularity to allow flexibility between local computation and global communication.

Suárez2020learning presents some evidence that Connectome is optimized for Edge of chaos computation by using Echo state network. Goulas2021bio instantiated and Damicelli2021brain have similar approach, considering connectome as a network architecture for certain tasks.

Liang2021can uses fly brain to train Word embedding.
