"To avoid this, the Stanford team used a type of PHP virus developed at CalTech that can be injected in the blood. The virus then crosses the blood-brain barrier to deliver its payload, an opsin gene, to brain cells. In this case, even the delivery of the gene is noninvasive—no needle penetrates the brain."
- superkuh 6y agoOh. So I missed the entire point of the paper. Yikes. Thanks for the correction. But how is the transfection localized to the VTA if it's administered peripherally and not within the target tissue?
- OpticalWindows 6y agoAlarm bells should be ringing about this. If they can breach the blood brain barrier with viruses, imagine what they can do with contaminated food, gas, and drink.

- superkuh 6y agoI've spent more time actually reading the papers and extended data. This statement written above is factually untrue. This procedure does involve needles in the brain. It is invasive. It is surgery. The press writers you quote misunderstood.
