I take issue with the "dendrites know more than neurons" bit. The fact that they respond to almost all inputs suggests they are performing a different function that a somatic spike. My preferred explanation for that is that any type of input can be predictive of a somatic spike and that has to be transduced somewhere. Specific patterns of concurrent input on a dendrite drive sub-threshold depolarization which is theorized to be key for sequence prediction.
