Evolution of the Neocortex

The evolution of the neocortex marks a significant leap in mammalian brain development, introducing complex structures that enhance cognitive abilities. Unlike fish, mammals exhibit unique traits, such as the ability to imagine future scenarios, which may hint at the neocortex's primary function. Despite its intricate design, the neocortex's role in perception remains a puzzling mystery, as basic perceptual skills appear comparable between mammals and fish.
