... in signalers (stimulus animals) impacts catecholamine concentrations in the forebrain (where olfactory and visual information are integrated and processed) of untreated lizard responders. We also tested whether AVT influences the relationship between forebrain catecholamine concentrations and communication...

... in parallel within each of the major tetrapod lineages and would have led to increased sensitivity to a broader frequency range and to modification of the preexisting circuitry for sound source localization.

... of lizards to elucidate the evolutionary origins of ZII stripes in Sauropsida. We focused on the central netted dragon (Ctenophorus nuchalis) but also examined cerebellar ZII expression in 5 other dragon species ( Ctenophorus spp.). In contrast to what has been observed in snakes and turtles, we found...

... terrestrial vertebrates, birds [Hall and Ross, 2007; Ross et al., 2007] and lizards [Hall, 2008], both show a robust correlation between eye shape and activity pattern. Nocturnal birds and lizards have larger corneal diameters relative to the axial lengths of the eye, probably to allow more light to enter...

...A. Gonzalez; F.T. Russchen; A.H.M. Lohman The afferent connections of the striatum and the nucleus accumbens of the lizard Gekko gecko were studied with retrograde tracing by means of horseradish peroxidase and Fluoro-Gold and with anterograde tracing by means of Phaseolus vulgaris leukoagglutinin...

...Malcolm R. Miller The papillae basilares of species ofeight families of lizards have been studied by scanning electron microscopy. Two basic types of simpler papillae basilares are found in species of three families, namely the Iguanidae, Agamidae and Anguidae. The papillae in all these families...

...Richard A. Sugerman; Leo S. Demski Western collared lizards, Crotaphytus collaris, were tested in three experiments using electrical stimulation of the brain. In experiment 1, agonistic behavior (defensive, aggressive and escape) responses were elicited in free-moving unanesthetized lizards...

...Fernando Martínez-García; Francisco E. Olucha; Vicent Teruel; Maria J. Lorente The amygdaloid formation of the lizard Podarcis hispanica can be divided into three main groups of nuclei on the basis of their input from the main and accessory olfactory bulbs: the vomeronasal amygdala, the olfactory...

... chemosensation. This paper describes units of exploratory behavior, including use of the tongue, in a microsmatic lizard, the green anole, Anolis carolinensis. This species employs its tongue in a manner suggestive of chemosensory exploration, but it possesses modest peripheral chemosensory organs and reduced...

... specificity. The present study was designed to examine the distribution patterns of dopamine, noradrenaline and serotonin in a telencephalic structure, the anterior dorsal ventricular ridge, of the sand lizard Psammodromus algirus (Lacertidae) using specific antibodies against each monoamine. The anterior...

... about how such ecological needs affect non-mammalian, non-avian species. In lizards, the putative hippocampal homologues are the dorsal cortex (DC) and medial cortex (MC). We examined the relationship between foraging ecology and the size of the DC and MC in congeneric male lizards. We predicted based...

...Piet V. Hoogland; Fernando Martinez-Garcia; Finn Geneser; Eefke Vermeulen-VanderZee The small-celled part of the medial cortex (Cxms) in lizards is comparable to the hippocampal area dentata in mammals. As in mammals, most of the afferents to this cortical area are arranged in sharply delimited...
