1. Evolutionary Pathways in Brain Morphology, Development, and Behavior in the Primate Lineage.
PMID:日期:2026-09-21The article collection 'How Primates Became the Brainiest of All Mammals: A Closer Look at the Evolution of the Primate and Human Cortex' presents a wide-ranging analysis of encephalization across primates and humans. The papers in the collection tackle multiple classic themes in primatology, from brain ontogeny and relative brain size to cortical reorganization and metabolism. Taken together, the contributions reveal how the primate brain is more than a scaled-up version of the basic mammalian design. The primate brain uniquely evolved towards the cognitive scaffolding that ultimately brought about modern humans.

2. Investigating map-like navigation and hippocampus homologs in teleost fish: Comment on Givon et al., 2023 "Lateral and medial telencephalic pallium lesions impair spatial memory in goldfish".
PMID:日期:2026-09-16This commentary critically examines the article by Givon et al. (2023), which reports that lesions to the lateral or medial regions telencephalic pallium (Dl or Dm) both impair allocentric spatial navigation in goldfish and concludes that both regions are necessary for this function. This interpretation challenges the extensive body of evidence supporting the functional dissociation between Dl and Dm. In particular, Dl's ventral subdivision (Dlv) has been shown to be essential for map-like spatial memory. In contrast, Dm has been associated primarily with emotional and motivational processes rather than spatial cognition. This commentary focuses on the fact that Givon et al's behavioral tasks (a plus-maze and a breadboard maze) lacked essential controls, such as systematic maze rotations and probe trials, that are necessary to rule out non-allocentric behavioral strategies. Moreover, the lesions are poorly localized, including some that extend well beyond the pallium and affect subpallial telencephalic regions and even the mesencephalic optic tectum - structures whose damage produces widespread sensorimotor and regulatory disturbances. Furthermore, the relatively high post-surgical mortality indicates nonspecific surgical effects. Overall, we conclude that Givon et al. (2023) does not provide convincing evidence for a role of Dm in allocentric navigation and does not undermine previous findings of a functional dissociation between Dl and Dm. We briefly discuss how these findings impact the ongoing search for a hippocampus homolog in teleosts and the larger effort to elucidate the neural mechanisms underlying spatial navigation in teleosts.

3. Synaptic Proteome Divergence in the Prefrontal Cortex of Tame and Aggressive Red Foxes (Vulpes vulpes).
PMID:日期:2026-09-07The biological mechanisms behind aggressive and affiliative behaviors are difficult to pinpoint. In the Farm-Fox Experiment, conventional foxes were selectively bred since 1959 in two different directions, one for tame and another for aggressive response to humans. The distinct differences in social behavior of tame, aggressive, and conventional populations are genetically based and the three populations live in conditions that control for factors that could impact social reactions, such as environment and social experiences. Genomic and transcriptomic studies of genetic differences among the fox populations have highlighted genes involved in synaptic processes in the prefrontal cortex. To investigate how the synaptic mechanisms differ between the three fox populations, synaptosomes were isolated from prefrontal and premotor cortex extracts of sixteen female foxes. Tandem mass tags with liquid chromatography tandem mass spectrometry (LC-MS) were used to identify and quantify the relative abundance of the proteins. The results were sorted into protein groups and compared between populations using a limma analysis to determine proteins with differential expression (DE). In the tame versus aggressive comparison, 174 protein groups were found to be DE, while only five were found in the conventional versus aggressive comparison. Most DE protein groups had lower fold expression in the aggressive population compared to tame and aggressive populations. ADGRB2 was found to be the most DE protein group, with 11-fold higher expression in aggressive foxes than in tame foxes. ADGRB2 was previously shown to affect depression-like behavior in mice and is involved in the vascular endothelial growth factor signaling pathway, that is known to influence neurogenesis. Enrichment analyses on the DE protein groups found gene ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways that were enriched in the tame versus aggressive comparison, including multiple, highly enriched terms involving ribosome and translation. Local translation at synapses plays an important role in synaptic plasticity and, as a result, can profoundly influence behavior. This study highlighted potential mechanisms that could underly the behavioral differences between tame and aggressive foxes.

4. Endocranial integration and modularity in an adult human sample with known age and sex.
PMID:日期:2026-09-05Cranial endocasts represent a key proxy for reconstructing brain morphology in human evolution. Despite major advances in virtual anthropology and geometric morphometrics, patterns of endocranial integration and modularity as well as their variation with sex and age remain poorly explored. In this study, we apply 3D geometric morphometrics and multivariate analyses, including a surface-based mapping of local integration, to a sample of 115 modern human endocasts to detect patterns of morphological integration and variations linked to sex and age. Five bilateral endocranial modules, corresponding to major brain regions (frontal, parietal, temporal, occipital lobes, and cerebellum), were defined. Our results reveal a strong covariation across endocranial modules, with the highest covariation observed between the frontoparietal region and between the occipital and cerebellar region. Sexual dimorphism is mostly exhibited in endocranial volume, whereas age-relates variation is associated with significant regional changes, particularly in the frontal region, without clear evidence of volumetric reduction. These findings provide new insights into endocranial integration and modularity, highlighting the value of endocast for investigating brain morphology, variation, and ageing in humans and across their evolutionary history.

5. Quantification of Olfactory Glomeruli in a Shark: Correlation with Body Size and Receptor Genes across Vertebrates.
PMID:日期:2026-09-02The vertebrate olfactory system is characterized by the projection of receptor neurons toward the olfactory bulb (OB), where axons converge into synaptic structures known as glomeruli. This study histologically investigates the OB of the small-spotted catsharks (Scyliorhinus canicula), a species featuring a remarkably restricted repertoire of 49 identified receptor genes. Despite its limited genomic repertoire, adult S. canicula possesses about 400 glomeruli per OB, organized into distinct medial and lateral domains. These glomeruli exhibit significant size heterogeneity, with diameters ranging from 40 to 360 μm; the largest units represent some of the highest values recorded in vertebrates to date. To contextualize these findings, a comparative dataset of 16 vertebrate species was analyzed using phylogenetic generalized least squares models. The results demonstrate that glomerular abundance is strongly associated with both receptor gene number and body mass (R2 of ∼0.94), highlighting a dual influence of genomic and allometric factors. Interestingly, the glomeruli-to-genes ratio in S. canicula (∼8.5) aligns more closely with medium-sized mammals than with other nonmammalian taxa. This research provides the first quantification of the glomerular layer in a chondrichthyan, revealing an organizational principle that diverges from other nonmammalian vertebrates.

6. Parallel evolutionary expansion of prefrontal projecting cerebellar lobules in primates.
6. 灵长类动物前额叶投射小脑小叶的平行进化扩张PMID:日期:2026-07-30[中文摘要] 复杂认知能力在灵长类中曾多次独立演化，然而趋同行为是否反映了对共同神经系统的修饰仍不清楚。我们采用系统发育比较方法（pANCOVA、AICc模型比较）研究了51个灵长类物种（103份标本）的小脑小叶扩张，以检验关于后部小叶相对于前部小叶扩张的四个先验假设。结果强烈支持Crus I——一个投射至前额叶的小叶——在认知复杂的阔鼻猴类（Cebinae、Atelinae）中平行扩张，并在猕猴超科、猿类和人类中独立扩张。主要投射至（前）运动区的小叶HVI则表现出类人猿和猿类普遍性扩张，而未出现Cebinae/Atelinae与狭鼻猴类的趋同。这种小叶特异性提示，认知趋同依赖于靶向的前额叶-小脑环路扩张，而非未分化的小脑生长。关键的是，Crus I的相对大小解释了自我控制行为测量中82%的方差以及一般认知中50%的方差，证实了其与行为复杂性的关联。我们进一步证明，种内变异显著小于等级间差异，验证了物种水平的系统发育分析。我们认为，延长小脑发育的异时性位移，结合认知复杂谱系所特有的延长幼年期，使得扩张的前额叶-小脑环路能够经历依赖经验的精细化。
[英文摘要] Complex cognitive abilities have evolved several times independently in primates, yet whether convergent behavior reflects modifications to common neural systems remains unclear. We examined cerebellar lobular expansion across 51 primate species (103 specimens) using phylogenetic comparative methods (pANCOVA, AICc model comparison) to test four a priori hypotheses about posterior lobular expansion relative to the anterior lobe.Results demonstrate strong support for parallel expansion of Crus I, a prefrontal-projecting lobule, in cognitively complex platyrrhines (Cebinae, Atelinae) and independently in cercopithecoids, apes, and humans. Primarily (pre)motor-projecting lobule HVI shows generalized anthropoid and ape expansion without Cebinae/Atelinae-catarrhine convergence. This lobular specificity suggests that cognitive convergence depends on targeted prefronto-cerebellar circuit expansion, not undifferentiated cerebellar growth. Crucially, relative Crus I size explains 82% of variance in behavioral measures of self-control and 50% of variance in general cognition, confirming its association with behavioral complexity. We further demonstrate that within-species variation is substantially smaller than between-grade differences, validating phylogenetic analysis at the species level. We suggest that heterochronic shifts extending cerebellar development, coupled with prolonged juvenile periods characteristic of cognitively complex lineages, enable experience-dependent refinement of expanded prefrontal-cerebellar circuits.

7. Spatial Mapping of Rapid Cell Turnover in the Reptilian Brain.
7. 爬行动物大脑中快速细胞更新的空间映射PMID:日期:2026-07-23The brain is highly dynamic with many vertebrates displaying brain cell turnover beyond embryological stages. Seasonally breeding animals such as green anole lizards exhibit seasonal differences in brain morphologies, behaviors, and circulating sex steroid levels in adulthood. However, how these morphological changes occur remains unclear. This study aimed to understand how brain structures change seasonally by examining the presence of proliferating and dying cells in response to rapid change. Non-breeding males were transitioned overnight into breeding conditions, and their behaviors and brains were collected before and 2, 4 and 7 days after transition. Immunohistochemistry was performed to examine activated caspase 3 (AC3; cell death) and bromodeoxyuridine (BrdU; proliferating cells) in the brain. We found significantly more animals displaying BrdU-positive cells lining the third ventricles 7 days post-transition. Moreover, a novel reptilian spatial map of AC3-mediated cell death and proliferating cells during this transitioning period was generated. The current findings can be utilized to understand neural plasticity in a vertebrate group that is understudied compared to mammals and birds.

8. The Morphological Underpinnings of Stage-Wise Cognitive Development: Recognizing Piagetian Transitions in Structural Brain Maturation.
PMID:日期:2026-07-10Jean Piaget's theory of cognitive development posits that human intelligence progresses through four distinct, sequential stages. While modern neurobiology recognizes a general posterior-to-anterior gradient in brain maturation consistent with Piaget's proposal, the specific correspondence between structural cortical reorganization and these discrete psychological transitions remains a subject of investigation. Here we examine the temporal correspondence between cortical shape change and Piaget's cognitive stages by analyzing ontogenetic trajectories and introducing a novel approach to quantify developmental alignment, with applicability to fossil organisms. We examined a cross-sectional dataset of human endocasts derived from CT scans of individuals aged 0-18 years. To quantify the brain developmental dynamics, we devised a new method based on a phylogenetic comparative approach, treating chronological age stages as an evolutionary lineage. We applied phylogenetic ridge regression to compute rates of shape change and charted them on the endocast across age stages to visualize areas of rapid expansion and contraction directly onto the endocast. We found significant fluctuations in the rate of endocast shape ontogeny that align well with Piagetian transitions. We observed a rapid phase of growth in all lobes peaking at age 2 (transition to the preoperational stage), followed by a distinct reorganization at age 7 involving parietal and occipital expansion (at the onset of the concrete operational stage). A subsequent shift in frontal and parietal dynamics occurred at age 11, corresponding to the onset of the formal operational stage. The temporal lobe is the last to develop. Extensive endocast contraction occurs in frontal and parietal lobes around age 15, consistent with the operation of synaptic pruning. These findings provide quantitative evidence that the emergence of complex cognitive faculties is biologically paced by discrete waves of cortical restructuring. Furthermore, the efficacy of this morphometric approach on endocasts validates its potential for reconstructing the evolutionary ontogeny of intelligence in extinct Homo species, offering a bridge between developmental psychology and paleoanthropology.

9. "Mind Over Muscle": Neural and Biomechanical Signatures of Expertise in Early Stone Tool Use.
9. “心智胜于肌肉”：早期石器使用专业技能的神经与生物力学特征PMID:日期:2026-06-18Understanding the cognitive and biomechanical foundations of early hominin tool use represents a central focus in human evolutionary research. Although interdisciplinary work on early lithic technologies has explored each of these aspects separately, few experimental approaches have directly examined the interaction between neural and muscular systems during stone tool use. This study adopts a recently developed interdisciplinary approach to explore the impact of cumulative tool-related expertise (practical "know-how") on the dynamic brain-body interplay required for efficient early hominin stone tool use. Our experimental design compares Experts (with extensive practical knapping experience), Intermediates (with only theoretical knowledge), and Novices (with neither) performing two of the earliest known stone tool behaviors in the fossil record: hammerstone nut-cracking and Oldowan-style flake cutting. Using simultaneous electroencephalographic and electromyographic recordings, we analyzed neural activity in the left-frontal, premotor/motor, and left-parietal cortices alongside selective muscular activation in the hands and forearms. Our findings show that, during flake cutting, Experts display distinct beta-band neural activity in the left frontal and premotor/motor regions, and to a lesser extent in the left parietal region, accompanied by overall reduced muscular activation. In the nut-cracking task, Experts show reduced muscular effort and slightly elevated premotor/motor involvement, though to a much lesser degree. Importantly, Experts also present significant neural differences between the two tasks, suggesting task-specific cognitive strategies related to motor planning and coordination. In contrast, Novice participants demonstrate greater reliance on higher muscular effort and left-lateralized parietal regions, likely reflecting increased engagement of visuospatial processing and understanding tool function and mechanical knowledge. Altogether, these findings provide critical insights into the brain-hand interplay required for humanlike early stone tool use and highlight cumulative practical knowledge ("know-how") as a decisive factor of neuromechanical efficiency in early hominin technological behavior. They also encourage future experimental research on increased sample sizes to adopt integrated methods that jointly consider neural and muscular dynamics.

10. A step forward in encephalization: the virtual endocast of the Middle Pleistocene hominin from Ceprano, Italy.
10. 脑化进程向前迈进的一步：意大利切普拉诺中更新世古人类的虚拟颅内模PMID:日期:2026-06-01The Ceprano calvaria from central Italy (~400 ka) offers crucial insights into human evolution during the Middle Pleistocene. Despite its relatively late age, when derived Neanderthal-like specimens already existed in Europe, Ceprano retains a remarkably plesiomorphic morphology. This article focuses on the endocranial anatomy of Ceprano, aiming to clarify its place within the process of brain reorganisation in the genus Homo during the Middle Pleistocene. We conducted analyses on both the original and retrodeformed reconstructions of the specimen, considering that the shape of the Ceprano's endocast may be influenced by taphonomic distortion. This dual approach is particularly relevant in endocranial studies, as retrodeformation may be problematic in removing meaningful information, such as cerebral asymmetries. Additionally, a cladistic analysis employing 34 discrete endocranial characters was conducted. Our data confirmed that Ceprano exhibits an endocranial capacity of 1165 ml, placing it at the threshold between H. erectus sensu lato and more encephalized human taxa. Both geometric morphometrics and discrete trait analyses reveal an intermediate condition, blending a low, platycephalic morphology with volumetric expansion and signs of cortical reorganization. Consistently, the cladistic approach points out that Ceprano represents the sister taxon to all Middle and Late Pleistocene encephalized hominins. Therefore, we suggest that Ceprano should be considered a proxy for the ancestral morphology of Homo heidelbergensis, involving a two-phase model of brain evolution, in which an overall cerebral enlargement preceded lineage-specific cortical reorganizations. Thus, its mosaic morphology highlights the neuroanatomical foundations preceding subsequent divergences within later Homo species.
