The trouble with phrases like 'neural structures' and 'language parsing' is that these descriptions still play into the "AI" narrative that's been used to oversell large language models.
Fundamentally, these are statistical weights randomly wired up to other statistical weights, tested and pruned against a huge database. That isn't language parsing, it's still just brute-force calculation. The understanding comes from us, from people assigning linguistic meaning to patterns in binary.
