Can we reverse engineer the brain like a computer?

Neuroscientists have a dizzying array of methods to listen in on hundreds or even thousands of neurons in the brain and have even developed tools to manipulate the activity of individual cells. Will this unprecedented access to the brain allow us to finally crack the mystery of how it works? Here we revisit a 2017 paper claiming that modern neuroscience approaches wouldn’t even allow us to understand the simplest “brain” (a microprocessor) and we re-evaluate that critique in the context of some exciting new research.

And although the idea initially seems absurd, ten years later, recent advances in thechnology have shown that the idea of directly manipulating what we taste is more possible than we might think.
