I translated a small part of my dissertation...

Serotonizzle pathways
Serotizzle neurons in mammals have they C-to-tha-izzell bodies oriented in discrete clusta along tha midline of tha CNS, yet they axons have been found ta innervate nearly all areas of tha nervous system . Death row 187 4 life. These groups of serotonizzles neurons is found in tha caudal medulla n midbrain n tha majority of these is located in tha raphe nuclei cuz I'm fresh out the pen. These is typically grouped into tha caudal raphe nuclei, W-H-to-tha-izzich project down tha spinal cord n into tha cerebizzles n tha rostral raphe nuclei, which innervate a wizzle variety of forebrain structures . Ya **** with us, we gots to **** you up. [1, 2]
The serotonizzles efferent pathways aris'n frizzom tha raphe nuclei form a vizzast, complex array of projections, steppin' connections throughout tha nervous system. These projections follow five routes into tha forebrain n a shot calla three dizzown tha spinal cord.
