Neural connectivity in brain tissue is imaged by labeling the extracellular space.
Since the early days of neuroanatomy, researchers had a choice between two opposed labeling strategies to image neurons and their circuits: label all or label few. In a study in Nature Biotechnology1, Michalska et al. advance a third strategy, achieving a comprehensive view of the nervous system — down to the level of synapses — by labeling the extracellular space in fixed tissue. This makes a new avenue of dense reconstructions of neurons in the brain available to many labs that use an ever growing set of enhanced and super-resolution microscopy techniques.
