A Model for a Correlated Random Walk Based on the Ordered Extension of Pseudopodia
Figure 4
The diagram shows the probabilities, angles and sizes of pairs of pseudopod extensions. Dictyostelium cells frequently extend alternating right/left splitting pseudopodia. Pseudopodia to the left are in red, to the right in blue, and the movement after two pseudopodia is in black. Indicated are the four possible movements with two splitting pseudopodia after the cell has made a right and left pseudopod. The probability for alternating right/left or left/right is (a), while the probability for consecutive right/right or left/left is (1-a), yielding the probabilities of the four pseudopod pairs. The angle between pseudopodia is φ.
