- Functional MRI and PET were discussed as high-resolution tools for detecting brain activity patterns linked to disorders like OCD or hormonal imbalances, while EEG and functional near-infrared sensors were highlighted as lower-cost, non-invasive but coarser alternatives.  
- The safety trade-off between MRI (no ionizing radiation) and CT/X-ray (mutagenic risk) was clarified, along with the distinction between post-mortem brain slice tomography and in-vivo functional imaging.  
- Participants speculated on “rebooting” malfunctioning brain regions through targeted cell replacement or nanobridge repair to reset pathological circuits without erasing memory or identity.  
- Neural pacemakers for epilepsy were cited as an existing example of implanted electrical modulation to suppress pathological activity, driven in part by a participant’s family history of the condition.  
- 23andMe’s personal genomics database was discussed as a potential acquisition target for Google, Carlyle, or defense contractors interested in large-scale data mining.  
- The channel’s paperbot automatically retrieved open-access PubMed articles (PMID 16625590 and 23241129) via LibGen and diyhpl.us mirrors, illustrating the community’s automated literature-sharing infrastructure.
