0:00 Human consciousness and quantum mechanics 

0:55 New study about tryptophan 

1:30 Penrose proposes consciousness is quantum 

3:30 But quantum states are difficult to produce 

4:25 Stuart Hameroff explains it with microtubules and anesthesia 

5:40 What is consciousness though? 

7:20 Anesthesiology research is exciting

8:05 Tryptophan connection 

9:25 Ok, microtubules - what are these? 

10:35 Microtubules could be the source? 

11:30 Disagreement with neuroscience 

12:10 New proposition by Penrose and Hameroff 

13:20 Basic explanation of everything 

14:10 First negative experiment 

15:25 Anesthesia experiment finds positive results 

16:40 Recent paper shows tryptophan can create quantum effects 

18:35 What this shows and why this is important 

19:25 Potential medical breakthroughs?
