The GABAergic system of the dorsal cortex of lizards: a combined HRP-GABA immunohistochemistry study.
1990
Abstract γ-Aminobutyric acid (GABA)-like immunoreactive (GABA-LI) neurons were found throughout the mediolateral and rostrocaudal axis of the dorsal cortex. They were horizontal, vertical and multipolar cells, mainly distributed in layers 1 and 3. GABA-LI boutons were diffusely distributed in layers 1 and 3, as well as forming basket-like images around layer 2 pyramidal perikarya. Double labelling experiments indicate that GABA-LI cells are an origin of and a target for rostrocaudal intrinsic projections within the dorsal cortex.
Striato-amygdaloid transition area lesions reduce the duration of tonic immobility in the lizard Podarcis hispanica.
2002
Neuroanatomical data suggest that the lizard striato-amygdaloid transition area is homologous with the mammalian central amygdala. In order to investigate possible functional similarities, tonic immobility was induced in adult lizards and its duration recorded. Each lizard was then randomly assigned to one of three treatments: (1) bilateral striato-amygdaloid transition area lesions, (2) bilateral dorsal cortex lesions or (3) untreated controls. Three days after trial 1, each lizard was subjected to a second trial and the tonic immobility duration recorded. The mean tonic immobility duration in lizards with striato-amygdaloid transition area lesions was significantly shorter (80.5%; p < 0.0…
