	Cerebral cortex - Wikipedia, the free encyclopedia
		The cerebral cortex is a brain structure in vertebrates.
		The surface of the cerebral cortex is folded in large mammals like humans, where more than two thirds of the cortical surface is buried in the grooves, called "sulci".
		The senses of vision, audition and touch are served by the primary visual cortex, primary auditory cortex and primary somatosensory cortex.

	The Cerebral Cortex
		Cortical origins are primarily from the parietal and frontal lobes, but there are projections with origins from all cerebral cortices, Motor control via extrapyramidal nuclei is via effects on brainstem (diencephalon, midbrain, pons, medulla), cerebellar and basal ganglia motor nuclei..
		Somatosensory cortex is highly organized by input source---and the body regions capable of the greatest sensitivity occupy the greatest amount of somatosensory cortex.
		The visual cortex of the occipital lobe is divided into layers which are involved in a "division of labor'..each receiving visual input and processing it somewhat differently, via projections to other cortical and subcortical regions.

		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.

	The cerebral cortex
		Of equal importance are the interconnections or inter-reactions between cortical areas, which have never been fully investigated due to a lack of technical means.
		Much of the present knowledge on the activity of the cortex comes from neurosurgical procedures and pathologic cases (injuries to the brain, cerebrovascular accidents, and brain tumors).
		Clinical experience and neurotherapeutic testing have indicated that psychiatric disorders (see Figure 5-13) are related to specific centers of activation in the cortex.

		If you were "built" in proportion to the amount of cortex devoted to each part of your body, you would look a bit distorted: you would have a big head and hands and a small torso and tiny legs.

	How precise is the connectivity in the cerebral cortex?
		If there is a plan to which the connectivity in the cortex conforms, then the connectivity of each individual cortex should be similar to the connectivity of any other cortex.
		In addition, many (probably most) of the connections in the cortex are short-distance, and we need to know about the precision of these too.
		The connectivity outside the cortex is more ordered, but even here the connectivity is not replicated between individuals at the level of individual neurons.

		The cortex therefore seems to be composed of generally similar general purpose cells, with a subtle innate code which takes the form of guidelines, rather than rules.

	THE CEREBRAL CODE by William H. Calvin (MIT Press 1996)
		The “interoffice mail” circuits of the cerebral cortex are nicely suited for this job because they’re good copying machines, able to clone the firing pattern within a hundred-element hexagonal column.
		Although the cerebral code is a true code, it surely isn’t going to be universal; I doubt that the spatiotemporal firing pattern I use for dog (transposed to a musical scale, it would be a short melody, perhaps with some chords) is the same one that you use.
		Next comes a dose of the local neural circuits of cerebral cortex, as that is where the triangular arrays of synchronized neurons are predicted, that will be needed for both the coding and creative complexity aspects.

		The basic lower brain consists of the spinal cord, brainstem and diencephalon (the cerebellum and cortex are also present, but will be discussed in later sections).
		One portion, called the substantia nigra, is involved in voluntary movements; when it does not function, you have the tremored movements of Parkinson's disease.
		Thalamus - The thalamus relays incoming sensory pathways to appropriate areas of the cortex, determines which sensory information actually reaches consciousness and participates in motor-information exchange between the cerebellum, basal ganglia and cortex.
