What is the default network neuro?

Could you elaborate on the concept of "default network neuro" in the context of cryptocurrency and finance? Is it a specific term related to neural networks applied to blockchain or cryptocurrency systems? If so, how does it contribute to the development or functionality of these systems? Alternatively, is this a reference to a broader concept in neuroscience that might have indirect implications for our field? I'm intrigued by the phrase and eager to understand its significance within the realm of cryptocurrency and finance.
