ADVICE

Data-Driven Brain Study

Begin with psychological or behavioral data when studying the brain.
This data-driven approach is crucial because behavior drives brain evolution.

INSIGHT

ART's Unexpected Origin

Adaptive Resonance Theory (ART) emerged from studying learning, not consciousness.
ART addresses the stability-plasticity dilemma: learning quickly without forgetting.

INSIGHT

Consciousness and Resonance

Conscious states arise from resonance with critical features representing qualia.
Not all resonant states are conscious; some support unconscious brain functions.

Steve and I discuss his book Conscious Mind, Resonant Brain: How Each Brain Makes a Mind. The book is a huge collection of his models and their predictions and explanations for a wide array of cognitive brain functions. Many of the models spring from his Adaptive Resonance Theory (ART) framework, which explains how networks of neurons deal with changing environments while maintaining self-organization and retaining learned knowledge. ART led Steve to the hypothesis that all conscious states are resonant states, which we discuss. There are also guest questions from György Buzsáki, Jay McClelland, and John Krakauer.
