Unfortunately this is wrong. There are not predictive cells, there are predictive dendrites. The “predictive state” of cells in TM leaves the cell as inactive. It is only AFTER the present input is matched that the cells in a “predictive state” become active. I was also confused by this, but if you don’t see this please read BAMI and take a look at [Issues in BAMI](https://discourse.numenta.org/t/issues-in-bami/8463)
