Comparison of the number of VGAT-immunoreactive perisomatic boutons per 100 μm of the perimeter (mean ± SD) of PHF-tau-negative neurons, and of type I and II PHF-tau-ir neurons, in CA1 field and parahippocampal gyrus (PHG; that includes the entorhinal and the perirhinal cortex) of patient P7.

Region		PHF-tau-negative	Pattern I PHF-tau-ir	Pattern II PHF-tau-ir
CA1	N° terminals	8.92 ± 4.51	6.76 ± 2.50	6.97 ± 2.90
	Total perimeter length	1,459 μm	1,503 μm	1,473 μm
PHG	N° terminals	13.07 ± 4.00	11.49 ± 4.20	12.70 ± 4.29
	Total perimeter length	1,366 μm	1,320 μm	1,471 μm
