Stimulation of which brain area can modulate the sensation of pain?
Endogenous analgesic system
 
periaqueductal gray (PAG)-projects to nucleus raphé magnus and rostral ventromedial medulla
 
project to the dorsal horn of the spinal cord- release serotonin and norepinephrine
 
Locus coerulus-Nor epinephrine
 
Stress induced analgesia:
 
release of endogenous cannabinoids such as 2-arachidonoylglycerol (2AG) and anandamide acts on CB1(Euphoria) and CB 2 (Pain)receptors
Superior olivary complex
Locus ceruleus
Periaquaductal gray
Amygdala
