I wonder if this is also the case for neurons in other animals. Probably it is, but it would be a stunning revelation if it is not the case.

- buboard 7y agonotably this kind of dendritic spikes has not been found in other animals which have been investigated for dendritic spikes extensively (mice, rats, monkeys)
- chmod775 7y agoFrom the top reddit comment: > This paper is amazing. What is missing from the description above is that this is the first example of how human neurons are qualitatively different than rodent neurons (not only more computation power, but categorically different computation). > ELI5: the way the biological human neuron implements XOR is by a formerly unknown type of local response to inputs, which is low below the threshold, maximal at the threshold and decreases as the input intensifies above the threshold. We never saw anything like that in any other animal. (link to the relevant figure from the paper) Rodents being presumably the go-to non-human object of study.
- dr_dshiv 7y agoOther differences of human neurons. I saw a presentation recently that said that populations of human neurons can synchronize to far higher frequencies than mouse neurons.
