When the best microscopes could barely resolve nerve fibres, this was not a problem: but the devil lies in the detail, and with electron micrographs taking us down to the macromolecular level of cytology, and with biochemistry finally beginning to explain how everything works, the brain was revealed for what it is--a mass of fleshy endocrine cells squirting their neurotransmitter messages at one another in promiscuous abandon.
Close up, the machinery looked almost organic -- it had that evolved complexity, unplanned and serendipitous, that you can see in electron micrographs of cells and in flowcharts of mitochondria.
