Ascending Tracts | Spinothalamic Tract

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds!
In this lecture Professor Zach Murphy will continue our ascending tracts video series. During this lecture we will be discussing the spinothalamic tract, also known as the ventrolateral system. We go into detail on how we distinguish sensations from our skin including the receptors, to then transmit signals of pain and temperature to the thalamus. We hope you enjoy this lecture and be sure to support us below!

[@kennethgarcia25]

This guy writes/acts/produces the best neuroanatomy/neurology lectures on the planet! Even in Medical School there was nothing but reading Kandel to provide such a high level of integration of the science! Any lecturer on youtube that is not of this caliber should be erased or there should be a clear grading system that allows such quality to rise to the top with any search! Phenomenal work Ninja Nerds!

[@maximusaeon1846]

To be frank I’m speechless, I’ve been excessively going back and forth the videos you guys upload. The content is so well structured sophisticated enough to give an into depth and amazing approach, whilst significantly simplified and not overwhelming for the viewer. It’s been almost a year for me using your videos, a life changer. I strongly believe that modern science needs tutors like you, and astonishing supporters like your team. You all stars. Cheerz

[@umemaalam1653]

Thank you, Zach, a decade later when I am no longer a struggling med student and have morphed into this full-blown skilled surgeon, Imma remember your name and how you helped me, and I hope to return the favour that you so graciously bestowed.
