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