Are the roots of consciousness hidden in the ancient deep brain?
SMRTR summary
Most scientists have long believed consciousness lives in the brain's outer layer, the cortex — but a growing number of researchers think it may actually originate in the deeper, more ancient subcortex. Children born without a cortex still laugh, play, and respond emotionally, suggesting some level of awareness. A new ultrasound technique may soon help scientists test this theory, which could reshape how we define consciousness across the animal kingdom.
