Do you think this is possible in the absence of functional annotations?

I think so. But it is hard.

We tried. Tough to infer connections, and to infer *changes* in connections is way harder. Must measure many synapses at 2 times.

Would be very curious to see his ideas.

I may come across as molecular annotation extremist, but I bet with enough static molecular detail one could get something indicating dS/dt where S is synaptic strength.

Some mol info like
#receptors or docked vesicles indicate ~strength, but other molecules probably serve to add or remove those — these latter \propto dS/dt. Maybe.1 reply 0 retweets 0 likes -

Example of this kind — and there is an antibody for it! http://science.sciencemag.org/content/363/6422/eaav1483 … Now just add DNA tag :-)

Really it would be a “force” F indicated by these molecules where F drives the first or second temporal derivative or strength, or some more complex model.

Do you lose dS/dt with *very transient* anasthesia such that you’d need to know some fast dynamics or membrane voltage to know dS/dt in the ~seconds around fast tissue fixation/perfusion/freezing?

Or is it encoded in the molecules that will be orchestrating to implement it? Just as *presence* of a repressor on DNA will impact transcription *rate* say?
