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

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?
