| Physiological condition | Cell pool position in region | Hemisphere | Qualitative density of NT in PS | Relative to basal | Annotation | Reference | Collator | | Chemical treatment: | anterior | left hemisphere | not present | not measured | No labeled cells have been observed in the anterior part of the parastrial nucleus, which corresponds to the “round nucleus” of Raisman and Field (’73). | Ju G., Swanson L.W. & Simerly R.B, 1989 |
| Chemical treatment: | posterior | left hemisphere | light | not measured | A few labeled cells are, however, found in its posterior extension. | Ju G., Swanson L.W. & Simerly R.B, 1989 |
