Cone Flash Response - Schnapf, Nunn, Meister and Baylor (1990) Equation 7

This is a description of an empirical equation used to describe the flash response of cone outer segments.

 
                 t   ^3
              (-----)
               tau_r               t   ^2       2 pi t
j(t) = jo ---------------exp( - (-----)  ) cos(--------  + phi)
                  t   ^3         tau_d           tau_p
           1 + (-----)
                tau_r
j(t) : the current as a function of time.
jo : a scaling parameter
t : time in milliseconds
tau_r : the rising phase
tau_d : the damping time
tau_p : period
phi : phase
