Super-resolution STED microscopy for the first time enables the long-term observation of synapses in the healthy and diseased brain
Nerve cells in the brain possess small protrusions, so called dendritic spines, to communicate with other nerve cells by forming a synapse. These contact sites can be both, short- or long-lived thereby existing for even up to an entire lifetime. Short-lived contact sites reflect an ever- adapting brain, which is necessary to process novel experiences. Long-lived, stable contact sites, on the other hand, form the basis of our memory. But even…
