What is the exact rule for cell activation in a column?

Let us say there exist learned sequences ‘ABC’ and ‘FBD’. When A columns fire, specific cells in B columns become active.

No, specific cells in B columns become predictive.

@Timo_1028

My question is, under which exact circumstances and how does a cell get activated?

1. If there are no predictive cells within an active column, all cells in the column become active (this is called bursting)
2. Any cells in a predictive state that fall within a currently active column become active
