    Great review by & Hiesinger on how to encode a wiring diagram using simple stochastic rules that fit into a genome!

    Cosyne = COmputational + SYstems NEuroscience Its scope is the union of systems & computational neuroscience If you are mainly interested in applying insights from neuroscience to AI/computation, then NAISys would be a good meeting to consider

    the purpose of estimating the KC between two brains isnt to say one is *more* complex, but to say how different they are. The small KC (~1 MB?) suggests it takes just a few lines (genetic) code to go from mouse to human: make bigger brain tweak for human cognition

    i dont understand this distinction. Hopi's expts show that genes determine whether the burrow is short or long. One mech to encode this in the genome involves a reward function on the length of the burrow (and a bit more). probably need more than "stop now" for birds

    absolutely! in fact, i argue that the fact that the human genome *could* have been much larger but isnt suggests that the rules for wiring up a brain are relatively simple (ie compressible)

    I'll see your great grand-uncle's goat glands, and raise you an "Effect of Mescaline on Phatom Limb Syndrome". This was a paper by Julius Zador, my grandfather's brother, in the Journal of European Neurology.

    i think he just liked the sound of it. Apparently, the Joyce reference was post hoc justification for the spelling.

    I thought they were arguing not simply that different forms of restriction lead to different levels of motivation, but rather that motivation is complex, not a unitary variable (which i agree with).

    Yes, I think Tanzi was the first to propose the synapse as the locus of plasticity. Combine that with William James' 1890 "Laws of Association," wait a half century, and you get a Hebbian synapse (in 1949).

    Two years before Sherrington coined the term "synapse," Freud postulated in his 1895 "PROJECT FOR A SCIENTIFIC PSYCHOLOGY" that "neuronal contact barriers" may change their state and thus "afford a possibility of representing memory” Foreshadowing Hebb.

    Tomasello wrote: "It is inconceivable that you would ever see 2 chimps carrying a log together". Yet de Waal reports examples of basically just that--eg animals cooperating to prop a heavy pole against a wall to escape.

    Brilliant book by Frans de Waal, "Are We Smart Enough to Know How Smart Animals Are?" This passage calls out the search for what makes human cognition unique as "neo-Creationism"--the idea that "evolution stopped at the human head".

    Overparameterization could contribute to better learning. But it can't explain why mice that build long tunnels build them even when fostered by short-tunnel parents. (Work of Hopi Hoekstra). A lot of what a lot of animals do is built into the wiring like this.

    I'm not sure what would be "big" or "small" synaptic changes. But in this experiment we monitor cortico-striatal synaptic efficacy in vivo in an auditory decision task while rats learn to associate a sound with an action. (From: Xiong, Znamenskiy, Zador, Nature, 2015).

    We pretty much know the parts list for how the brain works. If only we could figure out how to put those parts together

    I agree there is a tradeoff. But what would constitute evidence? How would you quantify "number of innate priors"? BTW I think even in primates most everything is innate. Maybe 99% in goats and 98% in primate--x2 higher, but still low. (Arbitrary units).

    Connectivity of 50K single cortical neurons from a single brain obtained by MAPseq. Part 2 -- some long-range projections of two of these neurons (it's hard to show all 50K at once). (Longwen Huang)
