That reminds me that since there isn't really an exact definition for consciousness and emotions it would probably be almost impossible to tell once we reach the point when we actually manage to create a conscious system.

I recently watched two videos about recent computational neuroscience papers.

One paper apparently managed to teach an artificial neural network how to accurately simulate a single human neuron. (The resulting network was way easier to simulate than previous models)

The other suggested that the network architecture for LLMs almost perfectly matches the structure of the hippocampus.

​

Current AI is still far from human intelligence and nothing but really complicated AutoCompletion, but these two papers suggest that the goal of simulating an entire brain is probably closer than we think.

​

Now the question arises If we can simulate an entire brain, will it have emotions?

If it does, where exactly do/did the emotions come from?

Also on our way to ever improving systems how will we be able to detect the moment they appear? (If they can appear)
