Sorry, no etymologies found.
The larger the neopallium, which is the center of a great variety of coordinations among stimuli and responses, the more complex the potentialities of behavior.
The neopallium is the dorsal cap of the brain, with frontal, parietal, and occipital areas, comprehending all that part of the brain which is the seat of the higher associative activities, reaching its fullest development in man.
With the larger and more recently developed mammals, therefore, the cerebral cortex, which by then had become all neopallium, must wrinkle.
This new portion of the OUR NEBVOUS SYSTEM 147 cortex is the neopallium (nee'oh-pal'ee-um; "new cloak" L).
Some mammals, as they increased in size, enlarged the area of the neopallium more than in proportion, so they increased in intelligence as well.
It is the enlarged neopallium, then, which makes mammals in general more intelligent than any other group of vertebrates and, indeed, more intelligent than any group of invertebrates.
However, there is a large expansion in the size of the neopallium, which spreads out to cover the top half of the cerebral cortex.
In the neopallium a greater variety of information is received and more complicated coordinations can be set up.
To enlarge the neopallium at that rate, however, meant that it would outgrow the skull.
This usually implies an increase in the size of the brain and, as a result, in the cerebrum and neopallium.
