“…Antisera against GABA itself or the enzyme responsible for its synthesis, glutamic acid decarboxylase (GAD), have been used to identify GABAergic neuronal populations and define GABAergic circuits of the brain in diverse vertebrate groups (Mugnaini and Oertel, 1985;Wu et al, 1986;Domenici et al, 1988;Schwerdtfeger and Lorente, 1988;Granda and Crossland, 1989;Schiffmann and Vanderhaeghen, 1990;Teruel et al, 1990;Albus et al, 1991;Bennis et al, 1991;Csillag, 1991;Reiner, 1991;Villeta et al, 1991;Watson et al, 1991). Two forms of GAD have been identified in mammals, GAD65 and GAD67 (Bu et al, 1992;Erlander et al, 1991).…”

“…As we have seen, CR and the majority of PV neurons are nonoverlapping populations of GABA-ir cells. It should be noticed, however, that they cannot account for the entire population of GABA-ir cells in the ADVR (this study, results not shown; Villeta et al, 1991), because GABA-ir cells are present throughout the mediolateral axis of the ADVR and in its three layers. Thus, the possibility remains that further subpopulations of GABAergic cells are present in the ADVR of reptiles, which could be characterized by the expression of other neuronal markers such as neuropeptides (cholecystokinin or somatostatin, Reiner and Beinfeld, 1985;Reiner and Oliver, 1987;neuropeptide Y, Medina et al, 1992).…”

“…In Psammodromus and in other lacertilian lizards (see Villeta et al, 1991;Andreu et al, 1994), three different cytoarchitectonic areas can be easily recognized (from medial to lateral) in the anterior aspect of the DVR (ADVR), which display a differential laminar organization (Fig. 1).…”

Calcium-binding proteins in the dorsal ventricular ridge of the lizardPsammodromus algirus

The aim of the present work was to study further the intrinsic organization of the dorsal ventricular ridge of lizards. For that purpose, the morphology and distribution of cells and fibers containing the calcium‐binding proteins calbindin‐D28k, parvalbumin, and calretinin were investigated by using immunohistochemical methods. Colocalization of calcium‐binding proteins with the neurotransmitter γ‐aminobutyric acid (GABA) was also studied because they are shown to coexist in many areas of the telencephalon where they define distinct subpopulations of GABAergic local circuit neurons. Neurons containing calcium‐binding proteins are limited to the anterior part of the dorsal ventricular ridge (ADVR), whereas the posterior or caudal portion of the ridge is devoid of immunoreactive cells. This result gives further evidence for defining both regions of the dorsal ventricular ridge. Calcium‐binding proteins mark three distinct populations of neurons within the ADVR. Two of them, parvalbumin‐ and calretinin‐expressing cells, are GABAergic. On the other hand, calbindin‐containing neurons do not express GABA, and the possibility is discussed that these cells are projection neurons. The distribution and overall density of fibers immunoreactive to calcium‐binding proteins suggests that most fibers are of extrinsic origin, the thalamic nuclei projecting to the ADVR and the lateral amygdala being good candidates for their origin. The comparison of data on the populations of calcium‐binding protein‐containing neurons in the reptilian ADVR with those of mammals illustrate the difficulty in finding a mammalian homologue for this controversial region of the reptilian telencephalon.

Immunohistochemical techniques were used to study the distributions of glutamic acid decarboxylase (GAD) and gamma-aminobutyric acid (GABA) in pigeon forebrain and midbrain to determine the organization of GABAergic systems in these brain areas in birds. In the basal ganglia, numerous medium-sized neurons throughout the striatum were labeled for GABA, while pallidal neurons, as well as a small population of large, aspiny striatal neurons, labeled for GAD and GABA. GAD+ and GABA+ fibers and terminals were abundant throughout the basal ganglia, and GABAergic fibers were found in all extratelencephalic targets of the basal ganglia. Most of these targets also contained numerous GABAergic neurons. In pallial regions, approximately 10-12% of the neurons were GABAergic. The outer rind of the pallium was more intensely labeled for GABAergic fibers than the core. The olfactory tubercle region, the ventral pallidum, and the hypothalamus were extremely densely labeled for GABAergic fibers, while GABAergic neurons were unevenly distributed in the hypothalamus. GABAergic neurons and fibers were abundant in the dorsalmost part of thalamus and the dorsal geniculate region, while GABAergic neurons and fibers were sparse (or lightly labeled) in the thalamic nuclei rotundus, triangularis, and ovoidalis. Further, GABAergic neurons were abundant in the superficial tectal layers, the magnocellular isthmic nucleus, the inferior colliculus, the intercollicular region, the central gray, and the reticular formation. GABAergic fibers were particularly abundant in the superficial tectal layers, the parvocellular isthmic nucleus, the inferior colliculus, the intercollicular region, the central gray, and the interpeduncular nucleus. These results suggest that GABA plays a role as a neurotransmitter in nearly all fore- and midbrain regions of birds, and in many instances the observed distributions of GABAergic neurons and fibers closely resemble the patterns seen in mammals, as well as in other vertebrates.
