Hey guys,
My neuro professor asked us an extra bonus question and I can't figure it out.
Where is one place anatomically where a single lesion above the foramen magnum can produce crossed extremity symptoms/signs (right arm and left leg)
??😕

Might as well state the obvious; best guess would be to figure out where along the medulla oblongata/cerebellar region this could happen.
