Experts use super-resolution microscopy to observe individual synapse proteins

In the synapses of nerve cells (neurons), there are hundreds of specialized proteins that are important for the functioning of the nervous system. If something goes wrong here, neurological or psychiatric diseases can be the result - Alzheimer's and Parkinson's, depression, and schizophrenia are just a few of them.
