Due to an editorial error, a function appeared incorrectly. The corrected function and surrounding paragraph appear below.

Fig. 2 B presents the same experimental Ca2+ spark ΔF/F time course as in Fig. 2 A, but now fit by the function

over the same interval as used in Fig. 1 A. The values of the parameters A, k1, d1, k2, d2, and C were adjusted to give a best least-squares fit of Fn. 2 to the experimental record. The resulting fit of Fn. 2, which has discontinuous derivatives at both its start and peak, closely follows all aspects of the experimental record in Fig. 2 and provides a better reproduction of the sharp peak in the experimental record in Fig. 2 than could be achieved using the function in Fn. 1.
