PLS description

[Paul Wicks]

Hi just browsing and saw the description for PLS. It's not true that the upper motor neurons aren't in the spinal cord. They originate in the primary motor cortex and descend down the spinal cord.

There they synapse with the lower motor neurones which go out to ennervate the muscle.

I contributed to a PLS info sheet for the MND Association which can be found here (http://www.mndassociation.org/document.rm?id=351)

I've removed the text you were kind enough to point out was incorrect, however, upon reading your document and reviewing the description it seemed to have been correct (to a laymen).
