Table 2 Mammalian brain regions associated with mating system and their putative homologs in teleost fishes (see [80] for a detailed discussion).

From: Integrating resource defence theory with a neural nonapeptide pathway to explain territory-based mating systems

Brain region Description
Bed Nucleus of the Stria Terminalis (BNST) Contains cell bodies of AVP- or AVT-producing neurons in tetrapods.
Medial amygdala Contains cell bodies of AVP- or AVT-producing neurons in tetrapods.
Supracommissural nucleus of the ventral telencephalon (Vs) Putative teleost homolog of the medial amygdala and BNST, but possesses no AVT-producing cell bodies.
Preoptic Area (POA) A neuroendocrine integration centre located at the interface of the hypothalamus and telencephalon. Contains groups of AVP- or AVT-producing neuron cell bodies that project axons throughout the brain.
Paraventricular nucleus (parvocellular subdivision in teleosts) Associated with stress and subordinate behaviour. In teleosts, part of the POA.
Supraoptic nucleus (magno-/gigantocellular subdivision in teleosts) Associated with aggression and reproductive behaviour. In teleosts, part of the POA.
Lateral septum (LS) In tetrapods, a collection of neurons in the medial forebrain lying generally anterior to the anterior commissure. Receives axons of AVP- or AVT-producing neurons. Associated with several types of social behaviour.
Ventral nucleus of the ventral telencephalon (Vv) Putative teleost homolog of the lateral septum.
Ventral pallidum (VP) A brain region immediately ventral to the lateral septum in tetrapods. Receives axons of AVP- or AVT-producing neurons. Implicated in social pair-bonding in rodents.
