"you may say [the brain is] not a machine, but you have to accept that it is also a system based on few simple rules"
Umm. Sorry, the 'rules' of neuron, astrocytes (glia), connectome, microglia, etc. are not 'simple' whatsoever. Please reread the Guardian article I linked above. I fully applaud and support efforts to expand neuroscience. But assuming we have the knowledge and expertise to now 'rewire' that conscious web, is hubris indeed. The brain is not wired and connected, it is evolving moment by moment. Glia potentiate and surround each synapse, adjusting the firing potentials in what is called neuroplasticity. Not by acting like little digital circuits, but invoking their synergistic ability to evolve towards more "wholeness" and heart-intelligence.
Pure intellect without heart and wisdom, is a time bomb that is already exploding in our faces. For the sake of the planet we must grow our abilities for empathy and care for all of life. Re-membering what indigenous peoples knew long ago.
