Well that's kind of a non-starter attitude isn't it? We don't know how neurons work so we shouldn't try to figure it out by emulating their behaviour with electronics? Analog neuromorphic approaches to not attempt to simulate neurons, they emulate them in silicon. Partly because of a belief that research in this area is required to produce ultra low power computational devices and partly to explore the real time dynamics of spiking neural networks. There are very few research groups working on this, but you can look up Kwabena Boahen's group at Stanford. They do large scale real time emulation and are currently building a sub threshold neuron accelerator for the neuro engineering framework from Chris Eliasmith at Waterloo which is famously used to create SPAUN. There is also the Karlheinz Meier group at Heidelberg university which does wafer-scale networks of neurons in accelerated time. Giacomo Indiveri at ETH Zurich has silicon neurons with on-chip learning circuits that the others are missing.
