Short answer: No. The blockchain essentially is a ledger, an accounting system. In order for that to work in a decentralised manner it's vital that each node have a complete copy of the data store and its history. The brain on the other hand isn't an accounting system. It's decentralised, too but its nodes - the neurons - serve a very different purpose than Blockchain nodes. They only need to 'know' about their immediate environment, i.e. the neurons around them. Therefore not only doesn't each neuron need to have a complete copy of the data available but it would rather be tremendously inefficient to do so.

I think the blockchain helps the transactions overcome trust issues due to fraudulent nodes on the decentralized network and thus there is a requirement of a complete copy of all the transactions to be present on each of the nodes. In a brain however, we may consider the neurons to be ideal nodes which will never act fraudulently. So if some data is stored on a neuron, all other neurons can completely trust that the data will not be tampered (due to lack of any motivation for a neuron to act fraudulently). That means we could skip the blockchain database part completely because 'trust' is naturally present in the network. Also now I'm not sure if there remains any further scope for us to apply the idea of decentralized operations to the functioning of the brain's neural network. Do point out if any ideas pop into your mind.

  Well, trustless trust is exactly the point of blockchain technology. If you can trust your participants anyway you don't need a blockchain. On the other hand, neurons aren't ideal nodes that never act fraudulently. There's plenty of false information or misfiring neurons in the brain. The brain is very good at error correction and heuristics, however. So, 'fraudulent' nodes aren't necessarily a problem.

Blockchains can contain arbitrary data not just transaction messages . . .
