• SPEED PLAYS
• if both strength and pain/temperature are
  impaired in a single limb, the lesion is either
  in the periphery or the cortex. The ALS carries
  crossed info in the spinal cord while the LCST
  controls ipsi muscles via LMNs. The ALS and CST
  are physically separated as they go up the brain
  stem, so usually are not damaged together.
  However, they are pretty close in cortex (pre-
  versus postcentral gyrus) and could be damaged at
  the same time.
• if there is reduced pain/temperature in one limb
  and reduced vibration sense in a contralateral
  limb, the level of the lesion is somewhere in the
  spinal cord (on the side of the
  vibration/position loss)
• increased reflexes in a symptomatic limb (after
  spinal shock) suggests a central (CNS/spinal
  cord) lesion reduced reflexes in a symptomatic
  limb suggest a peripheral lesion
• facial weakness ipsilateral to body weakness
  implies a lesion rostral to motor VII (rostral
  pon and above)
• both a third nerve palsy and a Horners can
  result in ptosis and pupillary asymmetrybut with
  a third nerve palsy the ptosis is on the side of
  the large pupil with a Horners the ptosis is on
  the side of the small pupil
• 6. diplopia is always due to a lesion in the
  brain stem or periphery (nerve/NMJ/muscle) but
  not in the cortex (frontal eye fileds). A gaze
  palsy (impaired movement of both eyes in one
  direction, but both eyes move congruently and
  remain aligned in all postions of gaze) is due to
  a lesion in cortex or brain stem, but not in the
  periphery

I guess this is it!! Sorry to see it end!!
