An atlas of the brain of the tench (Tinca tinca L., 1758; Cyprinidae, Teleostei).

This report provides an atlas of the tench brain in the transverse plane. The brain atlas is based on paraffin-embedded brains which are serially sectioned and stained with cresyl violet. It consists of drawings and photographs at several levels throughout the main divisions of the tench brain. The brain of the tench shows important variations in the shape, extension and boundaries of different brain areas and nuclei in comparison with those previously described in the brain of other teleosts.
