The coronal plane is perpendicular to the ground and to the sagittal plane (Figure 7. A single section in this plane could pass through both eyes or both ears but not through all four at the same time. A side view of the rat brain reveals three parts that are common to all mammals: the cerebrum, the cerebellum, and the brain stem (Figure 7. Notice that it is clearly split down the middle into two cerebral hemispheres, separated by the deep sagittal fissure. In general, the right cerebral hemisphere receives sensations from, and controls movements of, the left side of the body. Similarly, the left cerebral hemisphere is concerned with sensations and movements on the right side of the body. Lying behind the cerebrum is the cerebellum (the word is derived from the Latin for "little brain"). While the cerebellum is in fact dwarfed by the large cerebrum, it actually contains as many neurons as both cerebral hemispheres combined. The cerebellum is primarily a movement control center that has extensive connections with the cerebrum and the spinal cord. In contrast to the cerebral hemispheres, the left side of the cerebellum is concerned with movements of the left side of the body, and the right side of the cerebellum is concerned with movements of the right side. The remaining part of the brain is the brain stem, best observed in a midsagittal view of the brain (Figure 7. The brain stem forms the stalk from which the cerebral hemispheres and the cerebellum sprout. The brain stem is a complex nexus of fibers and cells that in part serves to relay information from the cerebrum to the spinal cord and cerebellum, and vice versa. However, the brain stem is also the site where vital functions are regulated, such as breathing, consciousness, and the control of body temperature. Indeed, while the brain stem is considered the most primitive part of the mammalian brain, it is also the most important to life. One can survive damage to the cerebrum and cerebellum, but damage to the brain stem is usually fatal. The spinal cord is encased in the bony vertebral column and is attached to the brain stem. Axons enter and exit the spinal cord via the dorsal and ventral roots, respectively. A transection of the spinal cord results in anesthesia (lack of feeling) in the skin and paralysis of the muscles in parts of the body caudal to the cut. Paralysis in this case does not mean that the muscles cannot function, but they cannot be controlled by the brain. The spinal cord communicates with the body via the spinal nerves, which are part of the peripheral nervous system (discussed below). Spinal nerves exit the spinal cord through notches between each vertebra of the vertebral column. Each spinal nerve attaches to the spinal cord by means of two branches, the dorsal root and the ventral root (Figure 7. Charles Bell showed that the ventral root contains axons carrying information away from the spinal cord-for example, to the muscles that jerk your foot away in response to the pain of the thumbtack. The somatic motor axons, which command muscle contraction, derive from motor neurons in the ventral spinal cord. The somatic sensory axons, which innervate and collect information from the skin, muscles, and joints, enter the spinal cord via the dorsal roots. Visceral motor fibers command the contraction and relaxation of muscles that form the walls of the intestines and the blood vessels (called smooth muscles), the rate of cardiac muscle contraction, and the secretory function of various glands. Derived from the Latin, afferent ("carry to") and efferent ("carry from") indicate whether the axons are transporting information toward or away from a particular point. The Cranial Nerves In addition to the nerves that arise from the spinal cord and innervate the body, there are 12 pairs of cranial nerves that arise from the brain stem and innervate (mostly) the head. Each cranial nerve has a name and a number associated with it (originally numbered by Galen, about 1800 years ago, from anterior to posterior).

We can only speculate, but perhaps they are related to patterns of sensation and activation in the autonomic nervous system. Obviously, one has to be cautious interpreting the maps, but it is intriguing that the different emotion maps are distinguishable, and this was even true to some extent for emotions not considered "basic. Anger Fear Disgust Happiness Sadness Surprise Neutral Figure A Color maps of six basic emotions. Subjects reported seeing only the expressionless face, but increased skin conductance still occurred. For now, the important point to remember is that measures of both autonomic response and amygdala activity correlate with the presentation of angry faces that are conditioned to be unpleasant despite the fact that the faces are not perceived. If sensory signals can have emotional impact on the brain without our being aware of it, this seems to rule out theories of emotion in which emotional experience is a prerequisite for emotional expression. But even with this conclusion, there are many possible ways for the brain to process emotional information. We now turn to the pathways in the brain that link sensations (inputs) to the behavioral responses (outputs) that characterize emotional experience. In the remainder of this chapter, we will see that different emotions may depend on different neural circuits, but some parts of the brain are important for multiple emotions. For example, neurons located in the retina, lateral geniculate nucleus, and striate cortex work together to serve vision, so we say they are part of the visual system. Broca defined the limbic lobe as the structures that form a ring around the brain stem and corpus callosum on the medial walls of the brain. The main structures in the limbic lobe labeled here are the cingulate gyrus, medial temporal cortex, and the hippocampus. The brain stem has been removed in the illustration to make the medial surface of the temporal lobe visible. Shortly, we will discuss the difficulties of trying to define a single system for emotion. Using the Latin word for "border" (limbus), Broca named this collection of cortical areas the limbic lobe because they form a ring or border around the brain stem (Figure 18. According to this definition, the limbic lobe consists of the cortex around the corpus callosum (mainly the cingulate gyrus), the cortex on the medial surface of the temporal lobe, and the hippocampus. Broca did not write about the importance of these structures for emotion, and for some time, they were thought to be primarily involved in olfaction. The Papez Circuit By the 1930s, evidence suggested that a number of limbic structures are involved in emotion. Reflecting on the earlier work of Cannon, Bard, and others, American neurologist James Papez proposed that there is an "emotion system," lying on the medial wall of the brain that links the cortex with the hypothalamus. Papez believed, as do many scientists today, that the cortex is critically involved in the experience of emotion. Papez believed that the experience of emotion was determined by activity in the cingulate cortex and, less directly, other cortical areas. The cingulate cortex projects to the hippocampus, and the hippocampus projects to the hypothalamus by way of the bundle of axons called the fornix. Hypothalamic effects reach the cortex via a relay in the anterior thalamic nuclei. Also, tumors located near the cingulate cortex are associated with certain emotional disturbances, including fear, irritability, and depression. Papez proposed that activity evoked in other neocortical areas by projections from the cingulate cortex adds "emotional coloring" to our experiences. In the Papez circuit, the hypothalamus governs the behavioral expression of emotion. The hypothalamus and neocortex are arranged so that each can influence the other, thus linking the expression and experience of emotion. In the circuit, the cingulate cortex affects the hypothalamus via the hippocampus and fornix (the large bundle of axons leaving the hippocampus), whereas the hypothalamus affects the cingulate cortex via the anterior thalamus.

There are also court hearing testimonies of psychiatrists and psychologists on record. All hernias which remain symptomatic following repair or multiple repairs are considered partial disabilities for a period of one to two years. Hernias, recurrent or not, which are symptomatic and require wearing a truss, may after two years be classified permanent partial disability. Common disfigurements of the eye include corneal scarring; defects of the iris and in some instances total loss of the eye with use of a prosthesis. Common disfigurements of the lips include loss of soft tissue, enlargement, and alteration of normal contour of the lips. Common disfigurements of the ear include loss of tissue and alteration of normal contour of the ear. Permanent scars and disfigurement of the face and neck are usually evaluated one year post-injury and/or one year after the last surgical procedure was performed. Scars and disfigurement involving the neck are limited to the region above the clavicle. The scar and disfigurement should be described accurately, using such parameters as length, width, color, contour, and exact location. Review past history, pre-existing medical conditions such as diabetes mellitus and hypertension, as well as habits such as alcohol, tobacco, and drugs. Physical Examination: Note general appearance, weight, habitus, type of breathing, blood pressure, pulse rate, heart sounds, lung sounds, signs of heart failure, and edema. Assess and review functional capabilities, physical restriction, level of activity causing symptoms, and ability to perform activity of daily living. Permanency is considered if two or more years has elapsed since the reported date of accident or exposure. A claimant with respiratory and/or cardiovascular diseases may be determined to have no work-related disability or a work related disability in one of the following categories: the examining physician should be familiar with the pathophysiology of the respiratory and cardiovascular system. Review the case folder, medical records, emergency room reports, and reports of hospitalization, and cardiac care. Industrial dust, such as asbestos, silica, wood-working dust, amosite, procidolite, aluminum, and disatomaceous earths, etc. Dyspnea is a major criterion in the assessment of the severity of respiratory impairment. Mild - walking fast on level or slight hill Moderate - level ground Severe - level and at rest Cough and sputum production. Diagnostic Testing Diagnostic testing reports should be reviewed and should correlate with clinical manifestations and physical findings: Chest X-ray - no definitive correlation between ability to work and x-ray findings. Listed below are key parameters that should be considered in the review of medical records. The claimant has a causally related respiratory disorder and/or impairment with pulmonologist documentation and an appropriate diagnostic test. The claimant is asymptomatic and stable, takes little or no medication and has complaints. The claimant is able to perform usual tasks and activities of daily living without dyspnea. The claimant may have complaints and episodes of exacerbation of respiratory symptoms. The claimant has multiple complaints such as chronic cough, shortness of breath and frequent exacerbation of respiratory symptoms. Dyspnea occurs on minimal physical exertion such as usual housework and activities of daily living, walking one block on level ground and/or climbing one flight of stairs. The claimant has a causally related respiratory disorder and/or impairment with a pulmonologist documentation and an appropriate diagnostic test. The claimant is symptomatic, under active respiratory care, may be confined to a chair or bed, may be O2 dependent, has multiple complaints and needs medication to control symptoms. There are positive findings on physical examination such as cyanosis, clubbing of the digits and positive lung findings.
