Not an expert, but one application of neural decoding you may be aware of is brain machine interfaces (eg Neuralink). By decoding motor intent we can create devices which offer movement to paraplegic individuals with external robotics. Decoding neuronal activity in other parts of the brain could allow us to directly interface with other neural functions. Imagine a machine that could interpret your perception of space or time (or even modify it).
Another application is in computing. Advances in the understanding of neuroscience have stimulated the creation of artificial neural networks (for example, the convolutional neural network was inspired by the cat visual cortex). Understanding how the human brain encodes concepts such as time or space might help us to design artificial systems.
Finally, the most important aspect of this work is (imo) advancing basic science. We don't understand how the brain works, and work such as this brings us closer to solving the grand mystery of neuroscience.
