except that small thing about inherent learning.... I know it is difficult to differentiate between big structures  which are strongly protein related (genes if you will) and then the connectivity which is basically celular communciation (no genes involved)..

but if you do separate both (and I agree at first order they can be separated as far as we know)..then you have to separate it completely... neuronal connections- both stablishing hte conenctions and sending signals through it- are neurons talking to each other... so inherent learning will be basically externally generated input where biochemichals act as carriers of external information... in that approxiamtion hormones and GABA and AMPA and NMDA and the chemotaxis biochemicals are there just to trasnmit enviromental signals so that neurons can talk to each other and decide how to connect or how strongly or in which clusters or..., not to generate the general brain structure, not to specify the connectivity.

I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
