This site told me more about the cortex. The differences in how the depth of the cortex changes in different parts of the brain is explained, as its role changes as the white fibers below it have different input locations depending on where in the brain you observe. The different neural layering patterns are shown with colored images, and the differences in how the neurons are connected in varying parts of the brain are also shown. The article also explains the advantages of having gyri in the brain, and how the general structure of the cortex is set us so as to maximize space efficiency. Compared to a mouse brain, which is smooth and does not have any sulci, it makes clear how these oscillating structures provide higher levels of cortical processing. This source also gives insight to how the cortex works, and proved to be of use when I was creating my brain portfolio.
