Answer 13

raphe nucleus
ventral tegmental
locus correoleus
basal forebrain- nucleus of myhert

Question 14

what neurotransmitter is from the raphe nucleus

Answer 14

sertonin

Question 15

what are the seretonergic connections from the raphe nuclues

Answer 15

pontomedullary neurones project to the spinal cord for the modualtion of slow pain
rostral pons projects to thalamus, limbic system and cerebral cortex
