An amputee moves her artificial limb using her brain. A Parkinson’s patient opts for deep brain stimulation (DBS) to reduce symptoms. A college student uses close-looped DBS to keep severe depression at bay. Through neuroscience research and neural engineering, the brain can now accomplish things once considered impossible. But with these advances come ethical questions about altering brain function.
In neuroscience and neural engineering, "we want to think carefully about what the consequences might be, especially because our brains are so intimately related to who we are," says Sara Goering.
“When we implant electrodes into brains for therapeutic reasons, all of a sudden you may be stimulating regions of...
