Incorrect Equations

Abstract

Woller A and Gonze D (2013) The bird circadian clock: insights from a computational model. J Biol Rhythms 28(6):390-402. (Original DOI: 10.1177/0748730413512454)

In the above article, Equations 4, 8, 11, and 12 were shown incorrectly. The correct equations are shown here, and are the ones that were used to obtain the results shown in the published figures

Equations (4) and (8) should read:

$$\frac{d{W}_1}{{\sigma }_{1}dt}=K_7{Z}_1-{\upsilon }_8{W}_1$$

(4′)

$$\frac{d{W}_2}{{\sigma }_{2}dt}=K_7{Z}_2-{\upsilon }_8{W}_2$$

(8′)

Equations (11) and (12) should read:

$$F_{12}={\upsilon }_c\frac{W_2^m}{K_c^M+W_2^m}$$

(11′)

$$F_{21}={\upsilon }_c\frac{W_1^m}{K_c^M+W_1^m}$$

(12′)

In addition, the parameter values given in the legend of Figure 3 are correct, however the units of υ₈ should be h⁻¹ and not nM/h.
