We built a century of neuroscience, and then an entire AI industry, around the cells we could measure.
Neurons are large and electrically active. They respond beautifully to the tools we had. So we mapped every connection, built the connector, scaled the graph, and called it intelligence.
Three papers dropped in Science last May, three labs, three different species, and they all said the same thing. The cells we ignored, the astrocytes, are the ones actually running the gain control, the attention switch, the memory consolidation, and the state transitions we call mood, fear, and arousal.
Every ADHD drug, every antidepressant, every PTSD medication targets this axis. The pharmacology was always right. The cell type attribution was wrong.
And every neural network ever built is missing the third terminal. At
@metacognitionai we are extensively working on this third terminal, understanding the bridge between memories and emotions and long horizon understanding of events.
Wrote about what this actually means for AI architecture and why I think it matters for where we take DAHN next.
