Visual pattern discrimination through interactions of neural networks: A combined electrical brain stimulation, brain lesion, and extracellular recording study in Salamandra salamandra

In freely moving S. salamandra various brain sites were stimulated monopolarly via chronically implanted electrodes. Stimulation of the optic tectum mainly elicited prey-catching behavior and sometimes predator-avoidance behavior. Telencephalic stimulation activated backward-creeping, trunk-raising,...

Description
Summary:In freely moving S. salamandra various brain sites were stimulated monopolarly via chronically implanted electrodes. Stimulation of the optic tectum mainly elicited prey-catching behavior and sometimes predator-avoidance behavior. Telencephalic stimulation activated backward-creeping, trunk-raising, or jaw-opening/closing. Brain lesions were produced in 64 fire salamanders either by anodal DC current, radiofrequency current, Kainic acid micro-injections, or micro-knife cuts. After ablation of the optic tectum, both visually guided prey-catching and predator-avoidance behaviors failed to occur.
