In a recent Nature article, Dr. Nicolas Tritsch highlights how limited our understanding of brain neurochemistry still is.

For all these kinds of questions, for the vast majority of molecules — we’re talking about dopamine, serotonin, acetylcholine and many others — we know virtually nothing

– Nicolas Tritsch

For him, the arrival of a new generation of genetically encoded sensors finally opens access to a previously invisible field: precisely measuring how much neurochemical is released during a nerve impulse, how many signals are required to trigger this release, and how long these molecules persist in the brain. A technological revolution that, according to Tritsch, is transforming the way researchers can probe and understand neuronal communication.
