Extended Data Fig. 4: Tomographic rendering of the PANTHOS neuron from a 5xFAD/TRGL mouse brain shown in Fig. 5a.

Serial z-stacked image (1 μm thick, number z1–z6) showing a flower shape structure of a PANTHOS neuron displaying the strongly fluorescent blebs with tapered necks arising from the perikaryal plasma membrane. The neuron is from the cerebral cortex layer V of 2.7-month-old male 5xFAD/TRGL mice. Scale bar 10 μm. Experiment was repeated 3 times independently with similar results.
