Percentages of basal dendritic spines in different morphological classes by genotype and spine lifetime classification^a

	Filopodia	Stubby	Thin	Mushroom
WT (all spines) undeprived	9	14	61	16
AP spines (day 1)	14	14	63	9
AP spines (day 14)	25	17	56	2
N spines (day 1)	26	35	31	8
NP spines (day 14)	28	13	54	5
αCaMKII-T286A (all spines) undeprived	2	4	87	7

^aAP, Always persistent spines, either viewed 1 or 14 d after CWD; N, new spines produced on the first day of deprivation (day 1) and day 14. αCaMKII-T286A mice in the last row and WTs in the first row were undeprived, and the general population were classified independent of spine lifetime.
