title: Methods to locate and track ion channels and receptors expressed in live neurons.
abstract: Brain cells use electrical and chemical signaling to communicate with each other and to send and receive information from the body. These neurons also encode information such as memories and are constantly adapting to changes as a result of positive alterations, such as learning, or negative events, such as neurological insults or neurodegeneration. In the last two decades, it has become clear that the placement of minute branches of neurons and, more importantly for the topic of this review, the placement of individual protein molecules, are the key events that enable neuronal network building and pruning. Advances in both electrophysiology and light-based imaging have allowed neuroscientists to answer fundamental questions about the key proteins involved in memory formation, maintenance, and loss. These findings have been enabled often through the clever use of chemical biology, biotechnology, and genetic engineering. In this review, we highlight numerous examples where chemical biology was used to provide new tools to answer difficult and near impossible questions in neurobiology.
