Lesions of the dorsal thalamus affected both the visuomotor behavior toward salient prey-like stimuli and the responses of visual neurons to these stimuli in the midbrain tectum of a salamander. The visual ascending pathways in amphibians essentially contribute to visual spatial attention as in mammals. Our findings support the view that cognitive abilities develop gradually along evolutionary lines.
