They talk about dendrite performing XOR, but computation here is grey-scale, not binary. Isn’t it more like computing absolute difference, perhaps between outputs of dendritic segments, which sum over active synapses?
It was mentioned in the Economist, out of all places, so I found open access link: http://www.mashqliu.com/Uploads/file/20201021/2020102120200969969.pdf
This XOR could be a huge deal, but I don’t understand the mechanism behind it.
What? Where (specifically)?
Science section, neuron modeling, page 71. It mentions Numenta too, as avoiding catastrophic forgetting.

Going from spiking to bursting, this just popped up on my Twitter feed:
