Rather, they appear to repair
entire brain circuits that had been faulty.
Optogenetics works at micro scale, and fMRI covers wide regions of the brain — together this means that scientists have a way to intervene and experiment with
entire brain circuits, to finally see how a certain type of brain cell affects the wider global activity of the entire brain.
Most recently, a technology called optogenetics has allowed experimenters to toggle
entire brain circuits «on» or «off» by shining laser light on genetically modified synapses.

If a traditional microchip is comparable to an electric
circuit (remove one piece and the
entire system collapses), this newtechnology is more similar to a human
brain.
Ultimately, the accumulation of multiple electrical signals throughout the
entire circuit of neurons produces
brain waves.
