Neuronal membrane trafficking dynamically controls plasma membrane protein availability and significantly impacts neurotransmission. To date, it has been challenging to measure neuronal endocytic trafficking in adult neurons. Here, we describe a highly effective, quantitative method to measure rapid changes in surface protein expression ex vivo in acute brain slices.
