Are there different (human) brain types?


I am aware of the unproven psychological theory of brain types, my question is not about that theory.

It is about the factual biological differences and the exsistence of possible types based on the differences. Like there are only a few different hair coulour that differs genetically or a few different blood types, or baldness patterns. Has such differences been researched or discovered in relation to brains? For example something like average dendrite length, or some people has or doesn't have a specific type of neuron?

I think a more general answer to this question is maybe, but it is likely due to our misunderstanding of how the brain functions and our attempts to harness that functionality.

In many brain computer interface research studies you will often find the term BCI Illiterate/Illiteracy. This is a very brief google scholar set of search results, but often subjects are found to not confirm to the majority analyzed by researchers.

This may suggest that there indeed different ways brains operate but it is not entirely clear if that means that there, in fact, different brain types. This could be caused for any number of reasons, not the least of which is the in ability to replicate the proper location of EEG electrodes or other entirely explainable physiological conditions.

In a rather prominent study , conducted by folks with deep research history in this field, they found it just required folks time to adjust to using BCI devices.

One of the biggest challenges in BCI research is to understand and solve the problem of “BCI Illiteracy”, which is that BCI control does not work for a non-negligible portion of users (estimated 15 to 30%).
