  GROSS NEURO-ANATOMY
Above the spinal cord is the brain, composed of the brain stem (medulla oblongata, pons and midbrain), the cerebellum, the diencephalon (thalamus and hypothalamus) and the cerebral hemispheres (basal ganglia, amygdala, hippocampus and cerebral cortex).
A loop of fibers from the cerebral cortex to the striatum to the globus pallidus to the thalamus and back to the cortex may be responsible for the cognitive degeneration (particularly related to language) seen with Huntington's Disease.
Analogous to the visual cortex is the olfactory and auditory cortex, which have a primary sensation area and proximal areas for sound or smell recognition.

The cerebral cortex is a thin (1.4 to 4mm) layer of mostly nerve cell bodies that cover the outer surface of each hemisphere of the brain.
Beneath the thin layer of the cerebral cortex lies the white matter of the brain —; vast networks of axons extending to and from the cortex.
Under the white matter lie the basal portions of the brain —; the basal ganglia that interact with the motor portions of the cortex and cerebellum to control movement and the thalamus and adjoining structures that are responsible for sensory processing.

 Cerebral cortex - Wikipedia, the free encyclopedia
Golgi-stained neurons in the somatosensory cortex of the macaque monkey.
The senses of vision, audition and touch are served by the primary visual cortex, primary auditory cortex and primary somatosensory cortex.
Thus, the cortex is commonly described as comprised of the primary sensory areas, the motor areas and the association areas.

The cortex is the outer surface of the brain (the cerebrum anyway) and is only 1.5-5mm deep.
The cortex is especially associated with non-life-sustaining cognitive functions.
Basically all of cortex is made up on the same types of neuron (pyrimidal neurons), but their connectivity is vastly different.

There are three general anatomical divisions of the frontal cortex: the limbic, the precentral and the prefrontal cortices.
The prefrontal cortex is anterior to the motor control areas and comprises the greater part of the frontal lobe.
The prefrontal cortex is the area implicated in the studies of personality and the behavioral effects of frontal lobe lesions.

 CORTEX
The main structures of the telencephalon include the basal ganglia, the cerebral cortex and the lateral ventricles.
The structure of the cortex varies from region to region.
The cerebral cortex is heterogeneous and can be divided into various regions based on a number of cytoarchitectonic features (i.e., cell size, cell density, cell type etc.).

 Sensory Cortex   (Site not responding. Last check: 2007-09-04)
The cortex is the top-most layer of the brain -- what you see just beneathe the skull -- with its characteristic folds and grayish hue.
Different regions of the cortex perform different tasks from motor output to the processing of sensory information.
For example, the visual cortex is located near the back of the brain and receives information from the eyes via optic nerve fibers.

 Structural Model and Neuroanatomy   (Site not responding. Last check: 2007-09-04)
Transmitted data arrives at the amygdala earlier than at the prefrontal cortex because the data going to the neocortex must be processed by the sensory and association portions of the neocortex before being available to the prefrontal cortex.
Accordingly it is clear that there are separate perceptual pathways to the ego and the unconscious, the one to the ego having been damaged and the one to the unconscious remaining unscathed.
The ego of the schema model is the clinical manifestation of the functioning of the prefrontal cortex; the pathogenic schema is the clinical manifestation of threatening perceptions registered by the amygdala and their associated affects, fantasies and subsequent assimilated experience.

 Morten L.Kringelbach's scientific research and papers   (Site not responding. Last check: 2007-09-04)
The human orbitofrontal cortex is an important brain region for the processing of rewards and punishments, which is a prerequisite for the complex and flexible emotional and social behaviour which contributes to the evolutionary success of humans.
One is a medio-lateral distinction, whereby medial orbitofrontal cortex activity is related to monitoring the reward value of many different reinforcers, whereas lateral orbitofrontal cortex activity is related to the evaluation of punishers which may lead to a change in ongoing behaviour.
The orbitofrontal cortex activation was related to the affective aspects of the touch, in that the somatosensory cortex (SI) was less activated by the pleasant and painful stimuli that by the neutral stimuli.

 Clinical Trial: Neuroanatomy of Emotion Regulation in Major Depressive Disorder
The amygdala has been shown to play a role in the learning of fear (aversive) conditioning to emotional stimuli, while areas of the prefrontal cortex are recruited for extinction of conditioned responses.
Dysregulation of connections between the amygdala and prefrontal cortex has been hypothesized to influence depressed subjects' tendency to ruminate on emotional events and memories, which may be associated with an inability to properly regulate emotional processing through habituation and extinction mechanisms.
This research will be used to evaluate neural processes involved in emotional dysregulation in MDD and may direct future research to potential therapeutic approaches for the treatment of mood and anxiety disorders with abnormalities in emotional processing.
