 BASIC CEREBRAL CORTEX FUNCTION OTHER THAN VISION
The orbitofrontal cortex is often associated with ethical, social or emotionally related behavior.
Portions of the cerebral cortex associated with the limbic system, such as the medial cortex and parahippocampal gyri, are often called the "limbic association cortex".
Also, the somatosensory cortex allocates more area for superficial structures of the face, whereas the somatomotor cortex is more concerned with structures responsible for mastication and vocalization.

 TCIY - 3.2 The Cerebral Cortex
This cortex area is a map of the body, and the map was determined by neurologists touching electrodes to different points on the cortex surface, and observing which muscles contracted.
This knowledge of the functional areas of the cortex did not come about from studying the actual structure of the cortex, but instead from two other methods: by electrically stimulating different points on the cortex and observing the results, and by observing individuals who have specific cortex damage.
This is similar to the primary visual cortex, in which more cortex is devoted to the center-of-view than to peripheral vision.

 BASIC CEREBRAL CORTEX FUNCTION WITH EMPHASIS ON VISION
The medial geniculate body is the relay nucleus between the auditory fibers and the primary auditory cortex.
In this view, we see, hear, touch and smell because there is a little person somewhere in our brain who sees the results of visual cortex processing, who hears the results of auditory cortex processing, etc. Yet the entire neural network view of the neocortex is that information processing is parallel and distributed.

As stress has been demonstrated to increase both NA and DA in the cerebral cortex [14-16], to rule out the possibility that the effect of LC stimulation might be influenced by stress, we performed the present study in anaesthetized rats.
As described for the cortex, during pauses NA levels were significantly different from the previously stimulated levels, with the exception of the fifth interval sample.
Electrical stimulation of the LC produced an increase in both NA and DA concentrations in the cerebral cortex of anaesthetized rats, superimposable to that previously demonstrated by our group in freely moving animals [12].

 The Cerebral Cortex
Some projections associated with pain are also associated with the Limbic cortex (possibly explaining the emotional response(s) (expletives(??)) to painful stimuli).
This system arises primarily from the pyramidal cortex (Parietal and Frontal lobes) and influences the excitability of spinal motor neurons either mono- or polysynaptically (via cord interneurons).
Pathways which carry somatosensory information from the body and from the head---the dorsal column-medial lemniscal system, the spinothalamic system, and the trigeminalthalamic system and trigeminoreticular system, respectively---will be discussed under the subject of tracts (to come).

He explores the ramifications of his insights into a wide range of cerebral functions, such as sleep, dreaming, awareness, problem solving, creative thinking, and the dynamics of nerve cell assemblies that make consciousness possible.
I attempted to apply these six darwinian attributes to our mental processes in The Cerebral Symphony and in “Islands in the mind,” published in Seminars in the Neurosciences in 1991, but at that time I hadn’t yet found a specific neural mechanism that could turn the crank.
In a book that parallels this one, How Brains Think, I explored those subjects in a general way but here I treat them as some of the predicted outcomes of a detailed darwinian theory for how our cerebral cortex represents mental images — and occasionally recombines them, to create something new and different.

 How precise is the connectivity in the cerebral cortex?
Secondly, I will concentrate on the cerebral cortex, because it demonstrates the point I make most clearly.
The literature does not actually contain any data about this, but the reason for this is clear to any neuroscientist: the connections of individual neurons in the cortex are so different between individuals that it does not even make sense to try to compare them.
However, we are not going to know if this is the case until modelers will become aware of this constraint, and analyze their models to see if they meet it.
