🧠 Human Brain is Two Separate Organs
Krista Conger at Stanford Medicine:
The new research finding shows that the human brain consists of two ancient nervous systems cleverly packaged together — a more primitive part that regulates our hearts’ beating, our breathing and other functions, and another that makes us distinctly human, capable of poetry, mathematics and wondering about our own origins.
The discovery could help explain why scientists have struggled for decades to grow certain types of brain cells in the laboratory — and it opens new avenues for studying devastating diseases that affect the brain stem, such as spinal muscular atrophy (also known as SMA) and amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig’s disease).
Fascinating.
This kind of discovery always serves to remind me about how much we don't know, and how much is still left to discover about the universe and ourselves.
