FFN = fluor false NT's = neurotransmitters</p>

<p>

To advance understanding of the brain, the ability to measure both nerve cell electrical spiking and &nbsp;chemical neurotransmission with high spatial resolution is &nbsp;required.</p>

<p>

&nbsp;In comparison to the development of voltage sensors &nbsp;and Ca2+ indicator dyes over the past several decades, high &nbsp;resolution imaging of neurotransmitter (NT) release at single synapses has not been possible.&nbsp;</p>

<p>

In this Viewpoint, we discuss &nbsp;two recent developments toward this goal, namely, the design &nbsp;of fluorescent false neurotransmitters (FFNs) and optical &nbsp;neurotransmitter sensors.</p>
