Check out this new fluorescent probe, 'FFN511', it has been used to
describe a new form of synaptic plasticity, where individual
dopaminergic synapses respond differently to stimulus frequency.
FFN511 allows characterizing neurotransmitter release at the level of
individual synapses, even on the same neuron. Check out this video
link and a recent =91science=92 paper, you can get hold of FFN511 from
