... nuclei of the mammalian amygdala, little is known about the neuronal diversity in non-mammals, making reconstruction of its evolution particularly difficult. Here, we characterize glutamatergic neuron types in the amygdala of the urodele amphibian Pleurodeles waltl . Our single-cell RNA sequencing data...

... in mammals and birds. However, if one is interested in the principles that shape the evolution of vertebrate cognition, work in amphibians is essential. To address this gap, we have developed a research program contrasting cognitive abilities and hippocampal neurobiology in two species of frog with distinct...

.... The identification of the dopaminergic innervation of a telencephalic structure homologous to the mammalian striatum in amphibians reignited a debate about the evolution of the basal ganglia in vertebrates. Ever since Pedro Ramón y Cajal described the corpus striatum in the frog [reviewed in Triarhou and del Cerro...

López; Lorena Morales; Agustín González The present immunohistochemical study represents a detailed spatiotemporal analysis of the localization of orexin-immunoreactive (OX-ir) cells and fibers throughout development in the brain of the anuran amphibian Xenopus laevis, a model frequently...

...Alice Schade Powers Studies of the relationship between behavioral plasticity and new cells in the adult brain in amphibians and reptiles are sparse but demonstrate that environmental and hormonal variables do have an effect on the amount of cell proliferation and/or migration. The variables...

... that (1) AVT/AVP plays an important role in regulating sociosexual behavior and (2) AVT/AVP concentrations change seasonally, we asked whether melatonin alters the number and/or distribution of AVT-ir neurons in the brain of a seasonally breeding amphibian, which would be a potential mechanism...

... proliferation can occur without gonadal hormone involvement in either male or female adult anuran amphibians, and confirms that it is independent of a behavioral response in males. Gonadectomized and implanted H. cinerea were exposed to either a recording of a natural chorus (‘Chorus’) or random pure...

... rabbit serum instead of the primary antibody. AVP antisera have been used by others in the past to identify AVT neurons in the amphibian brain [Boyd et al., 1992; Boyd, 1994] and the guinea pig anti-AVP antisera used in this study has been previously used to label AVT in Bufo brain [McLeod and Donald...
