Neuroscience says there is no Free Will? – That is a Misinterpretation!

Revised April 22, 2016

1. In 1983, Benjamin Libet conducted an experiment that apparently showed that our brain makes decisions before we become aware of it. When a person moves a finger, the brain activity appears to start before the person actually makes that decision. 

  • There have been numerous experiments conducted since then, and all experiments seem to confirm this observation, even though the time delays vary.
  • People are quite puzzled and some are very worried that we are just zombies run by a program in our brain.

2. Here is a video clip that illustrates the basic experiment:

Here is a recent youtube video on the same subject:

3. Scientists and philosophers have been debating whether these experiments show that man has no free will:

4. The second recent experiment is a bit more refined. Let us summarize that experiment:

  • The person randomly decides (no pre-planning) press a button at some time (let us take this time to be TM -M for the mind- making the decision)
  • He presses the button, the time of which is recorded electronically: TF (F for using the finger to press the button).
  • At the same time that he decides to press the button, he is watching the clock and makes a mental note of the “time” and after hitting the button, records that time too: TE (E for using the eye to see the time on the clock. It is important to note that TE is the time that the MIND says it saw the clock).
  • Finally, his brain activity is recorded by the sensors attached to his head, and let us take the recorded start of brain activity to be TB.

Here is a summary from the researchers (you can click on the figure to expand and then hit the back button on the browser to get back):

So, the researchers conclude that since brain activity started at TB before, either (i) him pressing the button (at time TF) , or (ii) him recording the “clock” at the time TE when he made the decision, the brain activity started before he made the decision.

  • The problem is that they ASSUME that the time, TE, that one gets off the clock is the same as the time, TM, that the mind makes the decision to press the button.

5. In Buddha Dhamma, mind is the precursor to every action that we do with the body, and gets the brain to it. The brain is the control center for the mechanical body to carry out both these tasks ASSIGNED BY THE MIND. The brain gets the finger to push the button and the physical eye to look at the watch.

  • Now the mind is in the manomaya kaya and is lined up with the heart of the physical body; the mind and the brain are connected by signal system that is analogous to how television or radio signals are transmitted (possibly electromagnetic; that is very fast). The brain communicates with the five senses via the nervous system, and those communications are slower.
  • Thus the brain gets the message from the mind to “press the button” and to “watch the clock”. Thus TB is ALWAYS later than TM.
  • Modern science has shown that, “It normally takes 0.4 – 0.6 seconds for the nervous system to activate available muscle motor units to contract,……”. (see, at the very end of the article: The finger movement involves muscles in the arm, and the eye movement involves muscles in the head and the eye).
  • Both actions of “watch the clock” and “press the button” are initiated by the brain per mind’s instructions via the central nervous system: The eye function circuitry can be logically thought to be a bit faster than the mechanical finger moving. Thus “watching clock” gets done first with the eye, and a little time later the finger has pushed the button. So, here is the time sequence per Buddha Dhamma (you can click on the figure to expand and then hit the back button on the browser to get back):

6. Any function of the body is controlled by the mind; here it is the mind that starts off the brain activity, i.e., TB is later than TM (the brain activity starts after the mind decides to take action because the brain needs to get the signal from the mind – located close to the heart- via the central nervous system).

  • Now the brain needs to carry out those two functions of pressing the button and look at the clock: since the vision circuitry is faster it gets done first; the mechanical movement of the fingers is slower and that gets done a bit later.

7. Now, let us go back to the first experiment. The only difference there is that the person is not recording the time. He just presses the left or right button. So, there are just two events recorded now instead of three events. All we have to do is to remove TE from the above two graphs.

  • It is simpler: His mind decides to push the button; the mind directs the brain to push either the left or right finger; and it takes some time for the brain to mobilize the muscles to move the finger. So, the time sequence is the same as in the same figure: mind decides (TM), brain starts working on it (TB) and the sensors attached to his head record that brain activity (wiggly line), and finally the finger pushes the button (TF).
  • As in the other experiment, the mistake is to assume that finger pushing happens SIMULTANEOUS with the mind’s decision. But the mind only gets the brain (the computer) to initiate the complex sequence of events to work the muscles in the arm and hand to move the finger, and that is the lag time.

8. The body is like a mechanical instrument, say, a sophisticated tank that is used to fire at the distant object. The operator is like the mind. He aims the gun barrel using sophisticated circuitry, and then fires the gun. He can drive the tank where ever he wants. But things do not, and cannot, happen simultaneous with the operators decision; the gun needs to be moved into position before firing.

  • The mind is controlling the body just like that. The finger (and the eye) in the above case(s) are just two instruments helping with the two  tasks of pressing the button (and reading the clock), and the brain is the “control center” that oversees both those activities on the command of the mind.
  • The connection between the body and the mind is explained in the post, “Brain – Interface between Mind and Body” and other posts on the gandhabba.

9. The mind is in the manomaya kaya (also called gandhabba); the brain is “computer-like” and controls the physical body on the instructions given by the mind. At death, the manomaya kaya with the mind leaves the body and both the body and the brain become lifeless; see, “Ghost in the Machine – Synonym for the Manomaya Kaya?“, “Manomaya Kaya and the Physical Body“, and “Manomaya Kaya and Out-of-Body (OBE) Experience“.

  • Therefore, it is clear that we are not robots controlled by a program running in our brain. The brain is just a sophisticated mechanical instrument that helps the mind with coordinating the tasks (like the computer in the tank in the above example that is helping the tank operator). But there are certain functions like breathing that the brain carries out without an input from the mind. We will discuss those in an upcoming post soon.
  • Any person has the POTENTIAL to do things in a scale that is unimaginable to us. We just do not realize the power of our minds; see, “Power of the Human Mind – Introduction“, and the follow-up posts.
