Dopamine nanosensors measure signaling between nerve cells

Göttingen researchers succeeded in measuring the release of the neurotransmitter dopamine from nerve cells with unprecedented accuracy. This enables scientists to study the mechanisms that control dopamine signaling in more detail and to better elucidate the development of related diseases.
