• A new PNAS study (http://www.pnas.org/content/early/2013/10/02/1312691110) overturns the long-standing assumption that cortical “barrel” columns are identical across the rodent somatosensory cortex, showing they are whisker-specific instead—raising doubts about the validity of simplified, stereotypic micro-circuit models used in large-scale brain simulations.

• Channel members debate the implications: some see the variability as a necessary correction that forces simulators to incorporate real neuroanatomy, while others warn it makes large-scale modeling far more complex; one participant argues the pragmatic solution is to “just digitize actual mouse brains.”

• There is criticism that the computational-neuroscience community avoids confronting raw neuroanatomical data, with a suggestion that even linking neuron-type identifiers to empirical NCBI entries would improve current abstract models.

• Participants demonstrate routine circumvention of paywalls: paperbot automatically retrieves PNAS and IEEE Xplore papers via libgen/scimag, underscoring the channel’s reliance on open-access workarounds for scientific literature.

• A side discussion explores offline knowledge tools: interest in a clean, e-reader-friendly Wikipedia bundle for devices like the Nook, dissatisfaction with existing 2×AA-battery offline units, and plans to extract the proprietary Merck Index CD-ROM into open CSV tables using mdb-tools to create a wiki-style chemical database.

• An open-science collaboration model is proposed in which detailed online lab-note sharing enables distributed replication of experiments, potentially solving the reproducibility crisis even if it increases per-participant costs.

• Cost and access issues around high-priced events are highlighted: participants balk at the $10 k Singularity University FutureMED fee and consider “crashing” the event, with claims that SU rarely ejects unregistered attendees.

• A brief report notes that cutting-edge intelligence-community meetups are expressing unexpected interest in certain undisclosed services, suggesting a potential client pipeline despite current budget constraints.
