This discovery is to molecular neurobiology what PCR and sequencing was for molecular biology, a simple, but smart and huge step that brings the opportunity to the research community to finally undergo real good quality research on brain’s function on animal models.
In vivo functional imaging is still needed, as this images are on postmortem brains, but anyway, this technique is going to lead to a huge amount of knowledge discovery and thousands of publications in the following years.
Moreover, potentially, this technique can be applied to any kind of tissue, thus, allowing the allocation of different receptors or molecules not in single cell or in tissue slide, but in a full interconnected an complex organ.
