Brown Sequard Syndrome | Animation | Explained Conceptually

An animated analogy to explain how all the clinical features of Brown Sequard Syndrome occur, including contralateral corticospinal and ipsilateral spinothalamic pathway involvement

I hope you found this analogy helpful :)
If you have any ideas for neurology concepts you would like an animated analogy for, let me know below and I'll add them to my list!

Thank you so much. I've been pulling my hair to understand this syndrome. You saved me from getting bald :)

[@nishtharana9158]

Wow, what an in-depth explanation of Brown-Sequard Syndrome, absolutely mind-blown!
This is so clinically relevant, thank you!

[@NeurologyAnalogy]

Hi Nishtha, happy you've found it useful!

[@isabellaiu6310]

thank you! finally found a video that could explain the anatomy clearly!! the diagram is rlly useful! keep up with it!!

[@NeurologyAnalogy]

Thanks Isabella for your kind words :)

[@nanszy]

Good stuff!

[@NeurologyAnalogy]

Glad you liked it :)

[@amrhamza6716]

Thanks for such amazing concept. I have a question please..
Are all superficial reflexes' afferent pathways passing through Spino-thalamic tract ?
Then why spinothalamic tract is Not a part of the reflex arc ???

[@NeurologyAnalogy]

Thank you for the kind words and question. You're correct that the nociceptive pathway (involved in superficial reflexes) does involve the spinothalamic pathway - by its name, it ascends up the cord (spino-) and goes to the thalamus in the brain (-thalamic). The reflex arc i.e. when assessing muscle stretch reflex, does not go to the brain, as this would take too much time for the motor action to take place (i.e. removing weight-bearing foot off sharp object), and so and instead synapses in the cord. This involves nociceptive fibres, but as well as ascending up the cord, they synapse directly on the motor neuron in the reflex arc. This is simplified but hopefully explains the point.

Hi ! Just found your Channel today and i really find you vidéos very much helpfu so Thank you for not going up on your thought so start This Channel.
I'd like To ses more vidéos about all kind of syndroms learned in neurology and one comparaison btween pyramidal and extrapyramodal syndroms please !

[@NeurologyAnalogy]

Sure thing, I have a whole list of topics I'm planning to animate into analogies (including what you've mentioned) that I am slowing working through :)
