Expression of the Emx-1 and Dlx-1 homeobox genes define three molecularly distinct domains in the telencephalon of mouse, chick, turtle and frog embryos: implications for the evolution of
Homologies between vertebrate forebrain subdivisions are still uncertain. In particular the identification of homologs of the mammalian neocortex or the dorsal ventricular ridge (DVR) of birds and
Immunocytochemical localization of dopamine and its synthetic enzymes in the central nervous system of the lamprey Lampetra fluviatilis
TLDR
Investigation of the distribution of dopamine‐containing cell bodies, fibers, and terminals in the brain and spinal cord of Lampetra fluviatilis revealed the presence of 10 populations of dopaminergic neurons, and Chromatography indicated that dopamine exists in considerably higher concentrations than noradrenaline in the lamprey brain, whereas adrenaline is absent.
Telencephalic afferent projections from the diencephalon and brainstem in the pigeon. A retrograde multiple-label fluorescent study.
TLDR
The sites of origin of ascending projections to the telencephalon in the pigeon were studied by means of the retrograde fluorescence technique following the injection of various tracers concomitantly into different regions of topographically distinct areas of one hemisphere.
Organization of the serotoninergic system in the brain of two amphibian species, Ambystoma mexicanum (Urodela) and Typhlonectes compressicauda (Gymnophiona)
TLDR
An immunocytochemical investigation was made of the distribution of serotonin (5-HT) in the brain of larval and adult Ambystoma mexicanum and adult Typhlonectes compressicauda, and a new interpretation of the limited development of the serotoninergic system in amphibians is given.
Distribution of serotonin-immunoreactivity in the brain of the pigeon (Columba livia)
TLDR
Comparison of the results in birds with those obtained in other vertebrate species shows that the organization of the serotoninergic system in many regions of the avian brain is much like that found in reptiles and mammals.
