Adult neurogenesis and "immature" neurons in mammals: an evolutionary trade-off in plasticity?
Brain Struct Funct. 2023 Oct 13. doi: 10.1007/s00429-023-02717-9. Online ahead of print.ABSTRACTNeuronal plasticity can vary remarkably in its form and degree across animal species. Adult neurogenesis, namely the capacity to produce new neurons from neural stem cells through adulthood, appears widespread in non-mammalian vertebrates, whereas it is reduced in mammals. A growing body of comparative studies also report variation in the occurrence and activity of neural stem cell niches between mammals, with a general trend of reduction from small-brained to large-brained species. Conversely, recent studies have shown that lar...

Neuroanatomical correlates of aggressiveness: a case-control voxel- and surface-based morphometric study
Brain Struct Funct. 2023 Oct 11. doi: 10.1007/s00429-023-02715-x. Online ahead of print.ABSTRACTAggression occurs across the population ranging on a symptom continuum. Most previous studies have used magnetic resonance imaging in clinical/forensic samples, which is associated with several confounding factors. The present study examined structural brain characteristics in two healthy samples differing only in their propensity for aggressive behavior. Voxel- and surface-based morphometry (SBM) analyses were performed on 29 male martial artists and 32 age-matched male controls. Martial artists had significantly increased mean...

Whole-brain gray matter maturation trajectories associated with autistic traits from adolescence to early adulthood
Brain Struct Funct. 2023 Oct 11. doi: 10.1007/s00429-023-02710-2. Online ahead of print.ABSTRACTA growing number of evidence supports a continued distribution of autistic traits in the general population. However, brain maturation trajectories of autistic traits as well as the influence of sex on these trajectories remain largely unknown. We investigated the association of autistic traits in the general population, with longitudinal gray matter (GM) maturation trajectories during the critical period of adolescence. We assessed 709 community-based adolescents (54.7% women) at age 14 and 22. After testing the effect of sex, ...

Manual segmentation of  the paraventricular nucleus of the hypothalamus and the dorsal and ventral bed nucleus of stria terminalis using multimodal 7 Tesla structural MRI: probabilistic atlases for a stress-control triad
Brain Struct Funct. 2023 Oct 9. doi: 10.1007/s00429-023-02713-z. Online ahead of print.ABSTRACTThe paraventricular nucleus of the hypothalamus (PVN) is uniquely capable of proximal control over autonomic and neuroendocrine stress responses, and the bed nucleus of the stria terminalis (BNST) directly modulates PVN function, as well as playing an important role in stress control itself. The dorsal BNST (dBNST) is predominantly preautonomic, while the ventral BNST (vBNST) is predominantly viscerosensory, receiving dense noradrenergic signaling. Distinguishing the dBNST and vBNST, along with the PVN, may facilitate our underst...

Improved Functionnectome by dissociating the contributions of white matter fiber classes to functional activation
Brain Struct Funct. 2023 Oct 7. doi: 10.1007/s00429-023-02714-y. Online ahead of print.ABSTRACTIntegrating the underlying brain circuit's structural and functional architecture is required to explore the functional organization of cognitive networks. In that regard, we recently introduced the Functionnectome. This structural-functional method combines an fMRI acquisition with tractography-derived white matter connectivity data to map cognitive processes onto the white matter. However, this multimodal integration faces three significant challenges: (1) the necessarily limited overlap between tractography streamlines and the...
