Actually over the last month, dozens of high impact papers in Science
and Nature have reported work that has shed light on this very question.
Until very recently, we thought the brain was constructed of two basic
cell types: neurons which processed information and glial cells which
provided structural support to hold the brain together. After a huge
collaborative effort called The Neuroscience Multi-omic Archive (NeMo)
to analyze which genes were active in which cells in which regions of
the brain to construct a catalog of brain cells, it turns out that we
were highly mistaken. There are over 3000 types of brain cells all which
have specialized functions.
Here are 23 papers in a special October issue of Science alone:
The largest atlas of the human brain ever produced:
Here is the NeMo archive if you want to browse the actual data:
I used to think it was mostly the connections between neurons that made
the brain so complex. But there are huge amounts of data rolling in that
is demonstrating that biological brains are even more complex than I
thought they were. And this complexity, of how many and where each of
the 3000 cell types of the brain are, could readily explain big
differences in intelligence between two brains of the same mass
belonging to the same species as well as intelligence differences
between species. This new data has implications for both AI and
uploading. We might not be as close to obsolescence as transformer LLMs
have had us thinking we were.
