title: GABAergic neurons in the septum of the lizard, Podarcis hispanica.
abstract: With an antibody to gamma-aminobutyric acid (GABA), GABA-immunoreactive somata and boutons were identified in the septum of a lizard brain. GABA-positive somata occur at all rostrocaudal levels and in all septal nuclei. Parallel acetylcholinesterase (AChE) staining revealed a similar distribution of AChE-positive neurons. GABAergic boutons were seen throughout the septal nuclei, and were more densely concentrated in the outer zone of the dorsolateral septum. Axons of the anterior pallial commissure contained GABA- and AChE-reactivity.
