Developmental Neurobiology, Volume 86, Issue 3, July 2026.ABSTRACT Although much is known about the encoding of experience, how the brain organizes neural circuits capable of learning and memory formation is largely unstudied. Canonical critical periods emerge from a convergence of maturation‐ and experience‐dependent processes.

NONLINEAR DYNAMICS AND THE SYNTHESIS OF ZEBRA FINCH SONG
International Journal of Bifurcation and Chaos, 2012 Behavior emerges as the interaction between a nervous system, a peripheral biomechanical device and the environment. In birdsong production, this observation is particularly important: songbirds are an adequate animal model to unveil how brain structures reconfigure themselves during learning of a complex behavior as song. Therefore, it is important to

Evolution of the avian digital pattern
Scientific Reports, 2019 Variation in digit number has occurred multiple times in the history of archosaur evolution. The five digits of dinosaur limbs were reduced to three in bird forelimbs, and were further reduced in the vestigial forelimbs of the emu.

Behavioral Relevance of Species-Specific Vasotocin Anatomy in Gregarious Finches
Frontiers in Neuroscience, 2013 Despite substantial species differences in the vasotocin/vasopressin (VT/VP) circuitry of the medial bed nucleus of the stria terminalis (BSTm) and lateral septum (LS; a primary projection target of BSTm VT/VP cells), functional consequences of this ...

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.Intranasal midazolam–butorphanol premedication in traumatised buzzards (Buteo spp.) aims to provide safer sedation by minimising mask induction stress. This method significantly reduces sevoflurane requirements while maintaining stable cardiopulmonary parameters. It is a safe and practical alternative that enhances patient welfare and induction quality.

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

eLife, 2015 Innate pluripotency of mouse embryos transits from naive to primed state as the inner cell mass differentiates into epiblast. In vitro, their counterparts are embryonic (ESCs) and epiblast stem cells (EpiSCs), respectively.

Functional Ecology, Volume 40, Issue 7, Page 1960-1978, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Heatwaves are becoming increasingly frequent across the Mediterranean and pose critical challenges for small passerines, yet the physiological and morphological limits to their resilience remain poorly understood.

Social organization and habitat use shape the gut microbiome of a marine fish
Journal of Animal Ecology, Volume 95, Issue 7, Page 1091-1107, July 2026.This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Sexual Dimorphism in the Early Embryogenesis in Zebra Finches
PLoS ONE, 2014 Sex-specific gene expression before the onset of gonadogensis has been documented in embryos of mammals and chickens. In several mammalian species, differences in gene expression are accompanied by faster growth of pre-implantation male embryos. Here we asked whether avian embryos before gonadal differentiation are also sex-dimorphic in size and what ...
