We can go for months and months and not have any new studies or information come out and all of a sudden there's lots.

I've been trying to understand this one. It's very interesting to me but I'm having trouble understanding the motor cortex just to begin with. It's a bit hard not having the full article, so maybe I should wait till I get to read that.

Postural control systems
"Corrective movements are needed to keep the centre of gravity within the base of support. To achieve this goal, co-ordination of the sensory, skeletal muscle and central nervous systems is needed."

So, what are we talking about here? The motor cortex? I see the term POS mentioned in gait control too, so I might be able to find out more in autism abstracts or other movement disorders articles.

So, I found a fair bit about it generally in a search engine and still don't know really what this all means. Anyone know more about this POS and Center of pressure (COP) displacements pertaining to movement or tics?
