How the fuck do they know what's happening inside of living things? Particularly with neurochemistry. You've got, let's say, a working brain. It's full of juices. You've got a science lab. How do you go about separating which juices are which and determining how they behave in the living brain?

what about using nanomaterials in chemistry?

Graphene is very interesting nanomaterial for me. I heard that grapheneis widespread and used in electronic. It has next characteristics Carbon > 99, 6%, Thickness (nm): < 3.0 , MB surface area (m2/g): ~80, Density (kg/m3): 2,2, Bulk density (kg/m3): 120, Electrical resistivity (Q.cm-1): < 0.15. I think you need to find graphene in special laboratories like it http://mstnano.com/products/graphene/

It takes a really long time and a lot of work and most of the time you will be wrong or overly simplistic in your interpretation of what is going on. Serotonin for example was so named because they believed at first its primary function was modulating the consistency of blood serum.
For the specifics though, the way they tell which neurotransmitters affect what is by looking for ligand receptors at the synapse. The neurotransmitter works by being a 'key' for a specific molecular lock on the receiving cell, which initiates its action potential to propagate a shifting ion gradient through the dendrite. Then, they follow the trail of that neuron chain's axons until they get to something that's a muscle or sensory cluster (or backwards, to a specific region of the brain) and then end up saying something like 'these neurons are part of a pathway connecting this behavior/sensation to control from this brain region, modulated by this neurotransmitter.' If you noticed this is not much different than the room of blind men describing an elephant by grabbing different parts, grats, you've been paying attention.
