# Key Points from IRC Discussions on Transhumanist Technologies

• Participants analyzed sensory nerve pathways, identifying three distinct groupings (pain, non-pain, and motor) with dedicated pathways from mechanoreceptors to the spine, which has implications for designing more sophisticated touch sensors in robotics.

• A technical debate emerged about CAD file formats, with users criticizing the significant information loss (described as "90%") when converting from parametric formats to mesh-based formats like STL, particularly relevant for open hardware projects like Contraptor.org.

• Users evaluated alternative approaches to parametric CAD modeling, comparing OpenSCAD with Python-based solutions using pythonOCC, focusing on which tools better preserve engineering information for collaborative hardware development.

• The Blue Brain Project was discussed as a significant neuroscience initiative, with references to Noah Hutton's documentary about the project and potential collaboration opportunities with project leader Henry Markram.

• Advanced visualization tools were shared, including GLC-Player for viewing 3D models across multiple formats and FreeREP (an open-source CAD/CAM math library), demonstrating the community's focus on open tools for technical development.

• Participants shared neuroscience research including papers on memory formation and willful modulation of brain activity in consciousness disorders, reflecting the channel's interest in cognitive enhancement and brain-computer interfaces.

• A novel gaze-tracking technology using voice coils and mirrors was referenced with a link to the "eyeseecam" project, showing practical applications of tracking technologies relevant to human augmentation.
