Key points discussed:
The limitations of vision-centric approaches to consciousness studies.
Evidence from decorticated animals and hydranencephalic children supporting the brainstem's role in consciousness.
The relationship between homeostasis, the free energy principle, and consciousness.
Critiques of behaviorism and modern theories of consciousness.
The importance of subjective experience in understanding brain function.
The discussion also explored broader topics:
The potential impact of affect-based theories on AI development.
The role of the SEEKING system in exploration and learning.
Connections between neuroscience, psychoanalysis, and philosophy of mind.
Challenges in studying consciousness and the limitations of current theories.
