Current research shows that mental events cause physical events, and scientists believe that examining individual nerves is the key to understanding how the brain works as a complete unit. Understanding the brain at the nerve cell level will allow scientists to understand how human consciousness works (Blakeslee, 1992). Furthermore, the thalamus of the brain is identified as the possible sensory connector because it emits 40 impulses per second that pass through the entire brain (Blakeslee, 1995a). These findings represent a serious implication for dualism because it states that the mind is not physical. If the mind is not physical, it cannot influence the physical body, then the dualist theory of bilateral interactions between body and mind is false. The above mentioned argument is supported by many other scientific facts and objections against dualism. For example, phantom pain is a well-known phenomenon in medicine. When people lose a limb, they often feel painful spasms in parts that no longer exist. Although neuroscience is still developing, scientists believe that sensory conflict is responsible for this phenomenon (Blakeslee, 1995b). The brain remembers the nerves that go to the missing limb and their previous function, so it can give commands through those nerves. However, the nerves do not receive feedback from the muscles of the non-existent limb, so the brain forcibly stops the movement (Blakeslee, 1995b). Over time, the brain creates new nerve pathways and adapts to the new geography of the body (Blakeslee, 1995b), so the person's perception changes and the phantom pain no longer persists. Phantom pain is just one example of how brain is wired to brain. consciousness. Every perception in the environment and every physical action causes changes in the...... middle of paper ......p paralysis prevents the body from moving while the mind dreams. In conclusion, the mind is non-physical, but there must be a common link between the body and the mind because several examples show their interaction. Perhaps the image of the body and mind as entities responsible for our ability to act in the external and internal world (Ryle, 1949) is correct, but the brain as a link is missing. The brain is obviously the meeting point that perceives sensations from both the external and internal worlds. The mind functions in the internal world and supplies thoughts to the brain. The body functions in the external world and provides sensory input to the brain. The brain combines both inputs and distributes them between the body and mind. This is how the body and mind are able to interact even though the mind is immaterial and the body is material.
