Medical schools around the world need to pull their socks up and provide benchmark lectures to their students such as this one.
This is pure genius! Why is this diagram missing in our books! Awesome doctor,. Awesome explanation!
It’s been so long since you uploaded. Thank you so much for all the hard work Paul. Forever grateful. :D
Paul bolin we missed you!
Glad to hear from you again!
I missed you so much! Thanks for sharing your knowledge once again!
Thank you for sharing all of your videos. They are great and I am deeply thankful for them and the work you've done to make them.
These lectures are a treasure trove of information which a family doctor should know.
Wish there was an easy way to send money to him.
Missed you man! Thanks so much for all the awesome content on your channel! It has been so helpful!!!!!
Paul bolin is back..... Thank you so muchhhhhhh
This comes exactly 1 week after my proffs. I looked for videos and couldn’t find it. I will make sure my
juniors benefit from it
These courses are good enough for any medical board exams through the world. So doctors please help your own countrymen and relatives because there are extreme shortage of doctors. Doctors are well paid and highly respected in the communities of your motherland.
Back after a long time...
Good to see you.
So will you upload regularly now?
So nice to hear from you. Thanking the Lord that He has kept you safe. Welcome back Dr. Bolin.

Thursday September 29, 2022. Neurology: Brain Stem Lesions (Midbrain [CN III, CN IV], Pons [CN V, CN VI, CN VII, CN VIII], and Medulla Oblongata [CN IX, CN X, CN XII]), Central Nervous System. Medial Cranial Nerve Anatomy follows: Oculomotor Nerve (CN III), Trochlear Nerve (CN IV), Abducent Nerve (CN VI), Hypoglossal Nerve (CN XII), while Lateral Nerves are Pathophysiology of Ischemia/Infarction and/or Compression: 1) Medial Medullary Syndrome (Anterior Spinal Artery [ASA]); 2) Lateral Medullary Syndrome (Wallenberg Syndrome) involves the Posterior Inferior Cerebellar Artery (PICA) and manifests as a 1) Loss of Gag Reflex (Mediated by Glossopharyngeal and Motor Vagus Nerve), 2) Vertigo, Vomiting Nystagmus (Vestibulocochlear Nerve), 3) Anesthesia due to CN V or Trigeminal Nerve, 4) and Chewing Difficulty (CN V2). Also, 5) Sympathetic Pathway is involved and manifests with Horner's Syndrome (Miosis, Ptosis, and Anhydrosis) along with 6) Contralateral Loss of Pain and Temperature Sensation (Spinothalamic Tract Involvement); 3) Lateral Pontine Syndrome implicates the Anterior Inferior Cerebellar Artery (AICA) and is Stereotyped by 1) Facial Drooping Symptoms and 2) Ataxia (Facial Nerve Origin), 3) CN VIII Symptoms: Vertigo, Vomiting and Nystagmus, 4) Facial Paralysis and Dysphagia (Cranial Nerve V, the Facial Nerve Involvement) ; 4) Medial Pontine Syndrome involves the Basilar Artery; 5) Weber Syndrome (Superior Alternating Hemiplegia) has the Paramedian Branches of the Posterior Cerebral Artery (PCA) will present with 1) Oculomotor Palsy (Down and Out Eye Morphology), 2) Upper Motor Neuron Paralysis (Contralateral Spastic Paralysis: Hypertonia, Positive Babinski Sign), 3) Contralateral Parkinsonism (Bradykinesia, Rigidity) due to Substantia Nigra (SN) Involvement; and the 6) Dorsal Midbrain Syndrome is Compression/Injury of the Rostral Interstitial Nucleus of Medial Longitudinal Fasciculus (riMLF), Structure Perfused by the Basilar Artery (Parinaud Syndrome) and Presenting with Upward Palsy or Best regarded as a Paresis; Aetiology is Compression; and 7) Cerebellopontine Angle Syndrome (CPAS) is Compression of the CN V (Ipsilateral Masseter/Temporalis, Medial Pterygoid and Lateral Pterygoid Muscle Weakness, Loss Of Corneal Reflex) and CN VIII (Acoustic Neuroma/Meningioma) showing 1) Tinnitus and 2) Hearing Loss; Ataxia (Cerebellum Involvement). A Non-Communicating Hydrocephalus is also Present in CPAS due to Fourth Ventricle Obstruction. In short, Cranial Nerve Involvement will hint as to Ischemia/Infarction/Compression Location while Motor and Sensory Deficits (Signs and Symptoms) will hint the Particular Involved Vessel. Goodness, Clinicopathological Correlation is indeed the Essence of Medicine. MD Paul W. Bolin, die Krankheit macht die Gesundheit aber ich manchmal dachte Gesundheit macht die Krankheit. Ich nur bin einer Mann. Prost!
nice to hear from you
This is a great video - thanks
Anterior spinal artery doesn't give off Pica branch it comes from vertebrae directly
Thank you 🙏🏻
Thank you soo much
Could it be? Dr. Bolin back at it again?
Thanks a lot Dr
THANK YOU
What an amazing video!
Amazing video
Welcommeeee backkkk
this is a really good mnemonic
Good to see you
Great video❤
this is gold
Great video, it helped me a lot but there is one thing that is not explained. What happens to the DCML for weber's syndrome because for medial medullary syndrome you mention loss of fine touch proprioception and vibration contralaterally but in Weber's syndrome you don't mention anything about DCML. Doesn't DCML run through there so it is affected or am I missing something. Other than that great video and you earned a new subscriber 👍.
7 years on this website wow
Excellent
Sir, I was looking for neurocutaneous diseases on hour channel? Please tell me which lecture would contain this.
amazing
My wife has brain lesions in her brain stem and cerebellum, 12 nuero docs and 2 yrs later noone has given her a concrete answer, any studies I can look at to help her understand them?
No estará en español 😣?
Dr.paul in previous lectures in ASA stroke you said that ASA supply STT and CST , so the dcml will not be affected in ASA stroke
here you say that in ASA stroke the DCMl and CST will be affected
You said that DCML supplied by PSA
Conceptual one ☝
Thank you very much sir. I am a 2nd semester student. I would like to pay once i reach the 5th semester. Thank you very very much
Hi, at 18:09 I think there's a small mistake. In lower motor neuron lesion, entire facial nucleus gone, so it should be entire ipsilateral face deficit, right? Please look into and confirm. Otherwise, this is amazing video, thank you!
I had the same concern, I think he mixed that up. if the facial NUCLEUS is knocked out it should only be the ipsilateral lower face that is not innervated, and the forehead will have innervation from the contralateral side. if the facial NERVE is knocked out it will be the entirety of the ipsilateral face that will not be innervated.
better than boards and beyond's rule of 4s video
6:55 I think you mean factors of 12. Yes, I'm knit-picking 😁
Missed you.
