I don't profess to be a neuroscientist, or any other brain-studier, so what you read here may not be 100% accurate, but it's what I can pull together about how the difference in 'wiring' produces these different results.
The Frontal Lobe:
I understand that it controls/regulates things such as emotions, some motor skills, impulse control, long term memory, and decision making. Studies into children with AS have found that there is reduced activity in this area when making a decision. This is purely my speculation, but I'm thinking that the further along the spectrum, the less this area reacts. Think Rainman - Raymond was completely unable to determine right from wrong, or to decide his future.
Also, deficiencies (or deviations from the norm) in this area could mean a reduced emotional response or emotional competence. If the neurons aren't firing like those of NTs, then behaviour will be different. Interestingly, the frontal lobes are involved with the sense of humour, and I know that some Aspies are described as lacking in that department. Quite importantly, the area believed to be involved with detecting deception, irony, and sarcasm is in the frontal lobes.
If there is simply a difference in structure, and not a deficiency in brain chemicals, this may explain the single-mindedness - the ability to be completely absorbed , the stubbornness, even the genius. Research into adult Aspergians has found higher levels of protein in the frontal lobes (cerebral cortex). This same difference may also be linked with the difficulty in social interaction. The communication between parts of the brain may be hindered by the different layout or concentration of hormones.
More activity in this region could account for better non-task memory: fact recall.
The Amygdala:
This is supposedly where the emotions are decoded. If they are incorrectly decoded, or the message is misinterpreted at the other end, then I believe that would result in 'emotional incompetence'. As this is also the area that deals with threats and senses. This could explain why some people have sensory overloads: they perceive 'normal' things as threats or as bad things, and this part of the brain takes over, trying to get the body away and possibly warning others (wailing and jerking).
Possibly, the difference in the structure means that people with an ASD could be hyper-vigilant or unable to shut certain things out. The amygdala is in constant contact with the cerebral cortex, and if it thinks there is danger, it will be sending more messages to the frontal lobes, causing anxiety.
It has also been linked to social emotional processing (empathy).
If anyone with learning or knowledge in this area wishes to contradict me, please do, as this is all speculation based on perfunctory research.
