Upper and Lower Facial Innervation by Corticobulbar Pathways, ie, The Difference Between Bell's Palsy and Stroke


So I was trying to re-appreciate a tidbit of neurology, and I remembered that I had drawn a diagram last year... so I searched through my notes and found it. I know it's crude, but honestly, it is the clearest way I've ever seen this phenomenon represented in picture form. The Grey star represents a central lesion, the Brown star a peripheral lesion (where the tracts that innervate upper and lower face have temporarily joined together to form the Facial Nerve).

I've described this specifically, so maybe eventually this will show up a Google if someone searches for something like this, and it'll help them. I hope so.
