If exactly one neuron magically disappeared from my brain, would my thoughts be significantly different?

One can ask an analogous question about a single neuron (and/or its synapses) being magically displaced.

I would like to know how "sensitive to initial conditions" or, rather, to fine details of structure is the activity of human brain.

This could lead to a philosophy of mind version of the old ship of Theseus philosophical thought experiment.

Also:

Has this version of the ship of theseus already appeared in the philosophy of mind literature?

    $\begingroup$ Your brain has neurons that are dying every minute. Ask yourself if your thoughts are significantly different in the time it took to read my sentence. $\endgroup$ – Bryan Chang Nov 20 '20 at 16:31
  • $\begingroup$ @Bryan Chang: but my thoughts are the thoughts of a brain in which certain neurons die every minute. How can I know that significant physiological changes wouldn't happen in the (counterfactual) situation in which those neurons did not die? :) $\endgroup$ – Qfwfq Nov 22 '20 at 0:24
