Extended Fig. 9. Dynamics of spine geometries measured in vivo.

Extended Fig. 9

(a) Time courses of the spine length, measured from the border of the dendritic shaft to the center of the spine, for five example spines tracked over 8 imaging sessions (left). Distribution of spine lengths (right; N = 344 spine observations).

(b) Time courses of the spine radius, measured from the border to the center of the spine, for five example spines tracked over 8 imaging sessions (left). Distribution of spine radii (right; N = 344 spine observations).

(c) Time courses of the dendritic radius, measured from the border to the center of the dendrite, at the location of five example spines tracked over 8 imaging sessions (left). Distribution of all dendritic radii (right; N = 344 dendrite observations).

(d) Experimental spine length time-correlation function and its exponential fit (Supplementary Methods, §VII).
