# Key Points from IRC Log

* Xentrac shared a Hacker News discussion about constraint programming, highlighting its importance in computational problem-solving: https://news.ycombinator.com/item?id=10793459

* Kanzure noted that visual cortex and auditory cortex simulations have shown success in predicting actual observed behavior of those brain regions, suggesting some visual phenotype data may be useful for brain emulation.

* A discussion about brain emulation clarified that what matters is not the visual appearance of brain matter but the neuron connection graph, weights, latencies, and other functional properties beyond simple connectivity.

* Maaku expressed interest in a roadmap for creating artificial neurons and neuron replacement, suggesting there could be preparatory work done now despite overlap with whole brain emulation efforts.

* Kanzure shared a link to "Status of tor hidden services proposals" documenting developments in Tor network privacy technology: https://lists.torproject.org/pipermail/tor-dev/2015-October/009762.html

* A brief discussion touched on computational requirements for brain simulation, with xentrac suggesting reading Kurzweil's books on projected computational power needed for different brain simulation approaches.
