John Trojanowski, of the University of Pennsylvania lead a research study that has isolated attest that seems to be 100% accurate in predicting who will develop Alzheimer’s. The results will be presented in Archives of Neurology.
The Inner Life of Your Brain
We now see that our personalities become fixed at a rather early age; some of us can, indeed, change our types (previous post), but itâ€™s somewhat hard.Â â€¦Â Most of us attributed these things to how Â neurotransmitters and hormones affect our brain centers.Â Yet, we also know that certain parts of the brain are associated with different behaviors.Â The medial orbitofrontal cortex is involved with rewards (as is the neurotransmitter dopamine); other regions are associated with threat response; still others with negative effects and punishment; lateral prefrontal cortex deals with planning and voluntary behavior; and, thereâ€™s a region associated with Â examining the mental states of others.
An upcoming publication in the Journal of Social, Psychological, and Personality Science (lead author Christopher Nave) indicates that our personality traits seem to be set at very early ages. This does not mean that people can’t change; it’s a more difficult process, but it can occur.
The ability to grow brain and spinal cord nerve cells is present at birth- and starts to disappear just like that as we age. So, when we incur an injury to the spine or the brain- the axons (as discussed earlier) can’t regenerate. It is thought that since these areas are replete with nerves and nerve fibers, they send signals to stop new connections from forming. By stopping new pathways from forming, our brain can’t be confused with by incorrect signals that could result from the new pathways.
Can we really read people’s dreams? Sorry, in spite of what Cobb says, we can’t do it- yet. (I am not telling you not to see Inception; I think the movie is among the most intelligent I have seen.) But, scientists are working on it. Here are some of the approaches being taken.
