- Discussion of non-invasive ways to observe tongue motion during speech production, including real-time MRI (cited YouTube video “Echtzeit-MRT-Film: Sprechen”) and the idea of imaging-friendly “tongue condoms” or barium mouthwash to avoid physical interference.  
- Debate on the feasibility of reading global muscle activation patterns: proposal to measure “total body-language” EM-field signatures as a universal animal communication interface, contrasted with the suggestion to tap directly into motor nerves instead.  
- Reference to fMRI’s temporal limits for tracking rapid muscular events; participants linked a Biology Stack Exchange thread on fMRI time-resolution and noted its reliance on blood-oxygen-level changes rather than direct electrical activity.  
- Sharing of extreme neuroplasticity cases: a 44-year-old man with ~90 % loss of cortical tissue and an IQ of 75, and a high-functioning mathematics graduate with “virtually no brain,” illustrating massive redundancy in human neural architecture.  
- Citation of retracted Frontiers paper on hydrocephalus and discussion of related conditions (Dandy–Walker syndrome, hydranencephaly) to question conventional views on minimal brain mass required for normal cognition.  
- Link to Lancet case report “Brain of a white-collar worker” and NCBI figure showing near-total ventricular expansion, highlighting reproducibility and image-provenance issues in such studies.  
- Exchange of transhumanism-themed web comics: SMBC strip “Ethics has been solved in summer 2013” (id=3717) and Dresden Codak’s “Caveman Science Fiction,” used to satirize progress narratives and bioethics debates.
