Secrets of the autistic brain-brain scans Reveal there is more to Autism Than Meets The Eye

It is evident that the autistic population is increasing exponentially in various forms ranging from Asperger syndrome through the profound classical Autism. What isn't clear is why. Recent studies on the function of the brain of autistic people have new clues and insight this diagnostic notable and people who endure.

RESEARCH ABOUT THE AUTISTIC BRAIN:

Science is beginning to find variations of specific genes, which seem to be related to--if not responsible for the incidence of autism, or risk of manifest in anyone (this is not new and there is much research on this topic)

Brain scans reveal that children with the variant "gene" seem to have more connections of nerve cells in frontal lobe, but less in this area and the rest of the brain, according to science translational medicine

Likewise, studies at the University of California LA used functional magnetic resonance imaging to establish that children carrying the variant "gene" had differences inside connections in the frontal lobe of the brain, as well as the differences between this area and the rest of the brain.

Scientists at the University of California in LA are starting to believe that the autistic brain is actually wired differently (Autism brain secrets revealed by verification; BBC News health. November 3, 2010):
According to Dr Ashley Scott-Van Zeeland, who led the research project, "the front of the brain seems to speak mainly to themselves-it doesn't communicate both with other parts of the brain and long-distance connections does not have the back of the brain," "in children with the version of the gene is not linked to risk of autism, the paths were linked more strongly to the left side of the brain. Those with the variant "risk", the paths were different, linking the lobe strongly to both sides of the brain ".

WHAT IS THE AREA OF THE FRONTAL LOBE?

It's beginning to seem clear that there is a significant difference in frontal lobe activity for autistic person (or those carrying "variant of gene") if diagnosed as autistic or not. So, what is this area of the brain and what role it plays in our lives?

Many say that the frontal lobe is what makes us human. It is part of the brain that is more highly developed in humans than the rest of the animal life on our planet.

Here is a brief list of responsibilities, thought to be associated with this specific part of the brain
Focus attention on a single taskConcentrationIntention behaviorDecision makingProblem solvingAbstract purposeful–distraction reasoningElaboration of behaviorConsciousnessWorking memoryJudgmentLogicOrganizationSocializationSympathy and thoughtControl of empathyHigher cognitive functionsThought to play a role in our spatial orientation

Emotions are generated inside the brain, but the frontal lobes "Manage" emotions and help us to streamline and make conscious choices, intentional about our behavior. The research also indicates that there is increased activity in the frontal lobe during meditation (studies on Tibetan monks). Many believe that this part of the brain seems to be the headquarters of our essence and nature

SOME SYMPTOMS OF DAMAGE TO THE FRONTAL LOBE:

To further illustrate the connection between the autism spectrum and frontal lobe area, the following is a list of some of the symptoms of damage to that part of the brain:
Perseverance (obsessive or repetitive behaviour) less sympatheticUnable social empatheticLess social cuesInappropriate read judgments and responsesUnable to detect when the other is trying to cheat themLittle spontaneous deadpan face of aggressions spontaneityDifficulty behavioral flexibility in the interpretation of the comments of environmentImpaired associated with learning (using external signals to help guide behavior) lack of inhibition (misconduct)

This is not a comprehensive list of symptoms. In fact, deep damage to this area of the brain can lead to significant personality changes in the subject.

Despite everything, the link between the activity of the frontal lobe and the autistic brain is becoming quite obvious to the reader informed.

WHAT IS ALL THIS?

It would be irresponsible of the author to declare any interpretation of the data as fact. Currently only can speculate. The only obvious is that more research is needed.

It seems logical to assume that more connections in the region of the frontal lobe mean greater activity and therefore increased the capacity in these areas to which this part of the brain is responsible.

In fact, it is good to remember that many of the strengths of the autism spectrum profile seem to be areas of frontal lobe function. Focus and concentration, logical reasoning, problem solving, abstract reasoning, working memory-very high functioning Autism spectrum people possess these skills in various forms in a greater degree. Note that these functions tend to be built-in functions that require internal communication only.

On the other hand, the autistic aspects that most would call weaknesses or "dysfunctional" are these capacities for communication with and comments from the external environment are crucial. This is where the wiring between the frontal lobes and the rest of the brain may be affecting performance negatively as communication is breaking within the brain.

Recognize that the autistic brain can be connected differently the neurotypical brain could be the beginning of a significant improvement in our understanding of this diagnosis. It could also be the beginning of an understanding that people may have superior abilities ASD in some areas and, therefore, can offer new ideas and contributions to the life on our planet.
