Intelle Brain The above mentioned time related scientific explanations are somewhat contradicted when we analyse the time related relationship between Brain and I, or more precisely the Brain-Time.
External and internal time measurement in relative to our brain is not the same time. The brain's external time is equivalent to the standard time as mentioned above and it is the same to all. However, the internal time measurement is much more complex, especially because it's individual.
When we sleep and dream, our individual internal perception of time is not correlated to the external time. We all experienced dreams that may be perceived as hours and more while in reality or externally it took minutes or less.
Sleep is essential for our brain. We spend about thirty percent of our life in sleep. Our survival and quality of life depends on adequate and qualitative sleep. Our daily responses and concentration during our diverse activities are dependent on our sleep. When we analyse patients with sleep disorders in sleep-labs, we observe the REM (Rapid Eye Movement) which correspond to brain activities during deep sleep and related to dreams. In general REM sleep starts after about an hour and half after falling asleep. Most of our dreams occur during this phase of sleep. We all dream and it takes actually about two hours per night. For us individually the time may take much more than that. The most vivid and real dreams we experience during the REM sleep.
During our lifetime the brain may be exposed to many diseases. It has been known for years that Alzheimer's starts in a brain region known as the lateral entorhinal cortex (LEC). This region of the brain is considered to be a major factor responsible of our long-term memory. Alzheimer may spread from the LEC to other areas of the cerebral cortex, a brain region involved in spatial orientation and navigation.
We humans have not only consciousness, we also have self-awareness. The major difference is that consciousness is awareness of our body and our environment, while self-awareness is the recognition of that consciousness. In other words, not only we understand that we exist, but we comprehend that we are aware of our existence. To be conscious is to think; to be self-aware is to realize that we are thinking. Self-awareness is awareness of me-the "I", my thoughts and feelings.
Now imagine that the brain is not an organ. Imagine that we are two beings one is our original brain and the other is "us" with our self-awareness ability and we are communicating with each other.
I'll switch the previous scientific language into our human common and easy to understand language using metaphors to clarify the issues discussed.
