Especially it is described about meso-cortical-limbic pathway, one of the dopamine routes. Meso-cortical-limbic pathway is known to work during exercise which works to relieve chronic pain.

The arrows indicate the crucial nucleus or component of these chemical transmitters. Which combination is correct ?

a.　Fig. 1 --------Nucleus accumbens

b.　Fig. 2 --------Ventral tegmental area

c.　Fig. 3 --------Locus coeruleus

d.　Fig. 4 --------Raphe nucleus

e.　Fig. 5 --------Habenula

1. a, b, c　　2. b，c，d　　3．c, d，e　　4.all
