Ultrastructural analysis of mutant synapses. (A) Representative electron micrographs of synapses in cultured cortical neurons from littermate α-synuclein KO (α-/-β+/+) and α/β-synuclein double-KO (α-/-β-/-) mice. (Calibration bar, 100 nm.) (B) Frequency distribution of the density of synaptic vesicles in synapses from α-synuclein KO (α-/-β+/+) and α/β-synuclein double-KO (α-/-β-/-) neurons. Synaptic vesicle densities were determined from randomized electron micrographs (see Supporting Materials and Methods).
