Its evolving domination in the mammalian brain involves its reception of wider and wider ranges of sensory information via the thalamus and the emergence of higher neural activities based on that data. Folding of its surface provides a large surface area for activity for the rich concentration of synapses. FTP name this layer of grey matter, also called the pallium, covering the cerebral hemispheres in most vertebrates.
