A new sequencing-based method uses molecular barcodes to trace synaptic connections among neurons. The approach enables large-scale brain circuit mapping and may help reveal how neural networks change ...
Alzheimer's is a devastating disease that results in memory loss and cognitive decline. It's caused by brain cells dying and the brain itself shrinking from a buildup of proteins. Millions of seniors ...
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 ...
