There is an IPSILATERAL Horner's
Syndrome (ptosis, miosis, dry face, etc.). The interruption
of the descending sympathetics (that no longer pass
to regions of the spinal cord below T1) means that there is
no sweating on the entire IPSI side of the body.
As
you can see from the figure to the left, there are several
spinal cord pathways that we have not discussed. These
pathways will be covered in the next few weeks. Right now,
realize that a lesion of the LCST, following a stroke, will
not disrupt all descending motor control. You
may have seen such patients and it is clear that there is
some motor control that is conveyed via several of the
pathways labeled below.
