Does Free Consciousness exist ？
I see a study: Discovery of quantum vibrations in ‘microtubules’ inside brain neurons supports controversial theory of consciousness shared on social media. Some one comments that this study indicates that human have free consciouness and the freedom comes from quantum process. I disagree with this comments. To oppose this comment clearly, I will raise and answer two questions. First, what does ‘microtubules’ do inside neurons ? Second what is free consciousness ? What does ‘microtubules’ do inside neurons ? The above picture is from Wikipedia. It shows the structure of a neuron and what ‘microtubules’ is in neuron. The way how neuron works is: A neuron collect chemical signals from many other neurons and generate a signal in the left side of the above picture and send the signal to the right side the above picture through the ‘microtubules’ and finally convert that signal to chemical material and emit them. So ‘microtubules’ is more ...
