Some scientists believe that quantum physics may be involved in the generation of human consciousness! It is postulated by Sir Roger Penrose that quantum processes take place in the microtubules of brain cells. This could explain the apparent time dilation effects that occur just before a car accident for example. how are quantum physics and neuropsychological processes related? How would quantum mechanics produce cognitive processes and consciousness? How could this explain out of body experiences and the perception of time moving fast or slow?
