  Cerebral cortex - Wikipedia, the free encyclopedia
The cerebral cortex, made up of four lobes, is involved in many complex brain functions including memory, attention, perceptual awareness, "thinking", language and consciousness.
Thus, the cortex is commonly described as comprised of the primary sensory areas, the motor areas and the association areas.
The cerebral cortex develops from the neural plate, a specialised part of the embryonic ectoderm.

 adrenal cortex - Hutchinson encyclopedia article about adrenal cortex   (Site not responding. Last check: 2007-11-07)
The cortex (outer part) secretes various steroid hormones and other hormones that control salt and water metabolism and regulate the use of carbohydrates, proteins, and fats.
The hormones produced by the cortex can be divided into three main classes according to their function.
It is clear that disease of the adrenal cortex can result from disordered function of the adrenal gland itself or of the pituitary gland.

 Programme   (Site not responding. Last check: 2007-11-07)
The key objective of CORTEX is to explore the fundamental theoretical and engineering issues necessary to support the use of sentient objects to construct large-scale proactive applications and thereby to validate the use of sentient objects as a viable approach to the construction of such applications.
CORTEX is directly in line with the overall objectives of Program II and many European resolutions and recommendations that emphasise the roles of citizens in choosing research priorities, particularly a growing group of persons with special needs [1].
CORTEX has a role to play in ensuring that we understand how to build large scale, proactive and autonomous applications in the future, it will also help to ensure the Europe is at the forefront of technological developments in what is an emerging and potentially massive future market.

 CORTEX: Instructions to Authors   (Site not responding. Last check: 2007-11-07)
CORTEX is an international journal devoted to the study of the inter-relations of the nervous system and behavior, particularly as these are reflected in the effects of brain lesions on cognitive functions.
Cortex uses SI units, but seconds and milliseconds are abbreviated to "sec" and "msec".
Cortex is listed in: Current Contents/Life Sciences, Science Citation Index, Research Alert, Scisearch, Neuroscience Citation Index (ISI), Index Medicus/Medline, Excerpta Medica, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Current Science, and Psychological Abstracts of the American Psychological Association, CABS (Current Awareness in Biological Sciences).

 BASIC CEREBRAL CORTEX FUNCTION OTHER THAN VISION
The primary olfactory cortex is also known as the pyriform (pear-shaped) cortex, corresponding to the anterior portion of the uncus of the parahippocampal gyrus of the temporal lobe.
The subdivision of the cerebral cortex into the frontal, temporal, parietal and occipital lobes is based on the names of the overlying bones in the skull.
The prefrontal cortex, areas anterior and inferior to the SMA, constitutes nearly one-third of the cortical surface, yet it is very difficult to study and its functions are poorly understood.

 Manual for Cortex
Cortex runs behavioral paradigms designed by the user, displays visual stimuli to the subject, collects neurophysiological and behavioral data, monitors and stores eye position data, and shows the results to the user during the experiment.
Cortex uses the first 128 of the 256 rows in the lookup table for single-color items such as bars and circles, and the upper 128 rows to hold the color values for bitmapped patterns stored in disk files.
Cortex then handles moving the bitmap underneath the window for you (starting automatically at the lower left corner) and jumps the image back to the beginning when the edge of your large composite image reaches the edge of the window.

 Webvision: Visual Cortex
Layer 1 is composed of a dense network of synapses formed between the apical dendrites of layer 2-5B pyramidal cells (Lund and Wu, 1997) and the collected inputs from LGNd K layers (Fitzpatrick et al., 1983; Lachica and Casagrande, 1992), the pulvinar, feedback pathways from extrastriate areas, nonspecific thalamic nuclei, and other subcortical regions.
Thus the striate cortex retains the retinotopic map of the contralateral visual field that is developed in the LGN.
It illustrates how the cortex is divided, and the same time, into two kinds of slabs, one set of ocular dominance (left and right) and one set for orientation.

 Exploratorium Magazine: Hair: page 2
Each hair shaft is made up of two or three layers: the cuticle, the cortex, and sometimes the medulla.
Underneath the cuticle is the cortex, which is made up of long proteins that twist like the curly cord on a telephone.
Since the cortex can't heal itself, the only way to get rid of split ends is to cut them off.

However, when the proportion of frontal cortex to the entire cerebral cortex was compared, the values for humans (36.4%-39.3%) overlapped with those of the great apes (35%-38.7%).
In other words, the proportion of frontal cortex to the rest of the cerebral cortex in humans and great apes is similar.
Earlier studies estimated the size of the frontal cortex by examining the surface of the brain.
