Neurons firing in real time

3D imaging of neurons from intact brain tissue. Green is to the amygdala, and purple is from the amygdala. This image is from a recent methods paper (https://www.nature.com/articles/s41467-019-09515-0#Sec15). Characterizing the precise three-dimensional morphology and anatomical context of neurons is crucial for neuronal cell type classification and circuitry mapping. Recent advances in tissue clearing techniques and […]
