The olfactory lobes are very large in fish that hunt primarily by smell, such as hagfish, sharks, and catfish. Behind the ...
The optic tectum allows actions to be directed toward points in space, most commonly in response to visual input. In mammals, ... In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called ... At a higher level yet is the primary motor cortex, a strip of tissue located at the posterior edge of the frontal lobe. The ...
