# Summary of #hplusroadmap IRC Log (Jan 13, 2017)

* Discussion about affordable home EEG technology, with user nsh asking about biofeedback devices for stress management and brain region activity monitoring, with chris_99 suggesting OpenBCI (openbci.com) as a potential solution using the ADS1299 chip.

* Kanzure shared information about CAV-2 (canine adenovirus type 2), describing it as "a neurobiologist's best friend" for gene therapy applications, which was subsequently added to the DIY biohacking wiki.

* Superkuh presented a controversial theory about neuronal action potentials, suggesting they involve electrical manipulation of reversible phase changes in the lipid bilayer rather than just the conventional electrical model, and shared a book on thermal biophysics of membranes.

* Discussion of ultrasound for brain stimulation, with debate about safety concerns including potential membrane disruption, blood-brain barrier rupture, and hemorrhage risks, though kanzure argued it's "the only thing that has a chance of working" for targeted brain stimulation.

* Kanzure announced an upcoming presentation at BEACON Center about directed evolution, sharing draft slides covering topics like mutagenesis and DNA synthesis, with yashgaroth suggesting improvements including references to degenerate synthesis and miniaturization of directed evolution apparatus.

* The Internet Archive's Wayback Machine Chrome extension was mentioned, highlighting that 49% of URLs referenced in U.S. Supreme Court decisions are now dead, emphasizing the importance of web archiving.
