_______________________
Venous via ThalamoStiate vein draining into internal cerberal vein

19
Q

Thalamic pain or “ Central pain syndrome “
decribe

A

Due to damage to spinal tracts carrying pain and temp from the periphery to thalamus

20
Q

Thalamic syndrome ?

A

Vascular lesion due to stroke in thalamogeniculat artery !
this casues decreased threshold to pain casuing over reaction to painful stimuli
