Table showing the number of neurons and mean values for AIS length and AIS distance to soma in AT8-immunopositive or AT8-immunonegative in the different cortical layers in each case.

	AD cases	Control cases
AT8 + neurons in Layer II (n/AIS length/AIS distance to soma)	28/27.4/5.9	12/25.8/2.4
AT8 + neurons in Layer III (n/AIS length/AIS distance to soma)	22/27.6/5.4	23/27.9/2.5
AT8 + neurons in Layer IV (n/AIS length/AIS distance to soma)	9/27.7/6.1	7/27.5/7
AT8 + neurons in Layer V (n/AIS length/AIS distance to soma)	16/22/4.1	47/27/5.2
Total number of AT8 + / AT8- neurons	75/120	89/70
Total number of neurons examined	195	159
AIS mean length in AT8 + neurons	26.3	27.13
AIS mean length in AT8- neurons	23.8	26.73
AIS mean distance to soma in AT8 +	5.4	4.2
AIS mean distance to soma in AT8-	6.9	6.1

Length and distance are expressed in µm. Mean values are calculated considering all individual neurons.
