    The names of the pathways also tell you a bit about what the pathways do. Ex. Cortico-spinal can be translated to cortex to spine which means it's going from the head to body. You can then deduce this is motor related. Ex. Spinothalamic can be translated to from spine to cortex. You can then assume that this is sensory. If you're short on time, this can at least help you eliminate some choices even if you don't know exactly what it is.

    These pathways are so forgettable that I have to re-learn it every now and then. These mnemonics make it easier. Btw, my teacher taught me a mnemomic for Brown-Sequard syndrome which makes it very easy that I remember it upto this point. I want to share it. DISC LION DISC is for SENSORY loss (below the lesion) DI = Dorsal column (Ipsilateral), SC = Spinothalamic tract (contralateral) For those wondering what about "At the level of the lesion", it's obvious. You can deduce that there'll be hyperesthesia on the same side, and nothing will happen on the opposite side. LION is for MOTOR loss. LI = Lesion (ipsilateral), ON = Normal (opposite) So, at the level of the lesion, you'll have LMNL and below the level of the lesion, UMNL. Even though motor is said to be "normal" for opposite site of the lesion, there will be some deficit in axial and proximal muscles because of ACST damage.

  • @AsadR43

    LST crosses instantly at spinal level, which is why in BSS you'll see contralateral effects for it. The other two tracts cross in Medulla. Their normal functions are contralateral, but BSS will show ipsilateral effects since it is dealing with a spinal (not cortical) injury. Hope that made sense!

    when you say that the effect for first two tracts(corticospinal tract and posterior colum) is ipsilateral you say that because of the variation of the decussation of the tract compared to the Spinothalamic tract( as in the decussation for the first two happens in the medulla and the decussation for the lateral spinothalamic tract happens in the spinal cord level). please correct me if im wrong.

    Why are there no pain and temp sensation loss at the level of Brown squard lesion? If the signal comes to dorsal nucleus then it need to cross to the opposite side via the lissauer tract which is destroyed…😅 Also I don’t remember adding 2-3 levels when localizing the level of lesion of spinal cord injury using either motor or sensory deficit like in ASIA classification.

    Because the first two pathways decussate at the brain stem level (not the spinal cord level) and we're dealing with SPINAL CORD injuries here and so the only pathway among the three that decussate at the SC level is the Spinothalamic (hence its effect is gonna be Contralateral). Hope it helped :)

    3 жыл бұрын

    This is a common feature for any spinal cord lesion, as the UMNs generally act to modulate mainly via inhibition the LMNs. With spinal cord injury, the damaged UMN and LMN at the level cause a LMNL picture at the lesion level, but below this, the LMNs are released from inhibition from the descending UMNs, causing UMNL features below the lesion level. If it helps, I have 2 animated videos on my channel; one on spinal cord injury that helps visualise the UMNL and LMNL issue, and a Brown-Sequard video also
