...The dependence of cell density b(x, t) on position and time is described by the differential equation abjat = -w (7) where the vector flux J would be given by J = - j.Nb +xbVc. (8) (See Keller & Segel, 1970.)...

...As in Keller & Segel (1970) one can adopt a phenomenological approach and proceed without waiting for the unfolding of microscopic detail, particularly as much of this detail does not affect the macroscopic phenomenon....
[...]
...On the basis of general macroscopic arguments, we have previously formulated an equation for the macroscopic flux of cellular slime mold amebae and have used it to describe the initiation of aggregation in that system (Keller & Segel, 1970)....

...Even though Keller’s and Segel’s stability analysis of the uniform state in [69] and the presented instability criterion is valid for a very general formulation of the system, the next “landmark” in the studies of the Keller-Segel model was the paper by V....

...It is possible that the reduction to two equations that was done in [69] was too restrictive to cover all observable generated patterns during the aggregation of mobile species....
