Neurons definitely compute. The dendrites that aggregate signals to initiate an action potential are not just simple summations but complex arrangements of signal promoters and inhibitors. The complexity of a pyramidal neuron is equivalent to a 5-8 layer artificial NN. https://www.quantamagazine.org/how-computationally-complex-is-a-single-neuron-20210902/ https://www.quantamagazine.org/how-computationally-complex-i... https://www.sciencedirect.com/science/article/pii/S0896627321005018 https://www.sciencedirect.com/science/article/pii/S089662732...

And that result is just from a computer simulation of a neuron that focuses on the dendrites and doesn't appear to extensively model the nucleus. "Unfortunately, it’s currently impossible for neuroscientists to record the full input-output function of a real neuron, so there’s likely more going on that the model of a biological neuron isn’t capturing. In other words, real neurons might be even more complex."
