New paper presenting rather compelling evidence that the stem-vertebrate Haikouichthys had paired lateral and supranumerary medial eyes (!!!), and proposing that the medial eyes may have deep homology with the pineal and parapineal organs.

Postnatal plasticity in the olfactory system of the juvenile swine brain - Brain Structure and Function Swine have an excellent sense of smell and highly complex olfactory brain structures, which play a crucial role in their complex social interactions. In other mammals the olfactory system is known to exhibit significant plasticity, even during adulthood. The aim of this study was to investigate postnatal plasticity in olfactory areas of juvenile swine brains by studying immature cells immunoreactive for the microtubule-associated protein doublecortin (DCX). Using immunofluorescence, we studied DCX coexpression with the cell proliferation marker Ki-67, and different neuronal markers. Our results show the existence of numerous DCX + cells throughout the olfactory pallial areas. In some of them, we found DCX+/Ki-67 + coexpressing cells, suggesting that they were proliferating. Some of these proliferating cells were grouped in tangentially-oriented migratory-like chains, forming the rostral migratory stream to anterior olfactory area and olfactory bulb. Moreover, chains of DCX + cells were found in the external capsule and white matter adjacent to the temporal horn of the ventricle. Chains of DCX + cells were observed crossing the internal layers of the piriform and entorhinal cortices. In layer II of these cortices, DCX + cells of varying maturity degrees and neuronal phenotypes (including NeuN expression) were present. This suggests the existence of multiple migratory streams along the anteroposterior axis. Most DCX + immature cells in the migratory chains and in the anterior olfactory area, piriform and entorhinal cortices expressed the transcription factor Brn2 (Pou3f2), suggesting the incorporation of new glutamatergic neurons in these areas. Together, these results highlight the interest of swine to study the role of postnatal brain plasticity and their potential for regeneration in large, gyrencephalic brains.

Happy to share our new article with Júlia Freixes, Fatma Abdel-Rahman, Roberto Nebbia and @edesfilis.bsky.social on postnatal plasticity in olfactory areas of the juvenile swine, published in Brain, Structure and Function link.springer.com/article/10.1...

Remarkable. Uncontrollable laughing or crying can happen *without* emotion ("pseudobulbar affect"). Here's a video of one individual whose crying is triggered by real or imagined rubbing of his finger & thumb. Intense response but not sadness. /1

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

They exhibit fear responses hours after the source of their anxiety is removed. These responses can be reduced with an anxiolytic, such as alprazolam. They have also demonstrated high-level learning.
