- A ScienceDaily article (https://www.sciencedaily.com/releases/2021/07/210722113052.htm) was shared reporting that researchers have successfully reversed age-related memory loss in mice.  
- The experimental protocol required direct intracranial injection of a viral vector at six separate sites in each mouse brain, highlighting the invasive nature of current gene-therapy approaches for cognitive rejuvenation.  
- Discussion participants expressed concern over the invasiveness of the six-site stereotactic injection procedure, noting it as a significant barrier to translation in larger mammals or humans.
