By tagging neurons with molecular "barcodes," researchers mapped connections among thousands of neurons in the mouse brain with unprecedented speed ...

Expansion microscopy enabled researchers to count the number of connections between neurons (green points on purple neuron). Neurons exposed to amyloid-beta formed more connections (SSBs = single ...
