The primary somatic sensory cortex projects in turn to allergy medicine and decongestant 10mg aristocort for sale higher-order association cortices in the parietal lobe allergy medicine like benadryl cheap aristocort 10 mg with amex, and back to allergy treatment xanthoma generic aristocort 4mg on line the subcortical structures involved in mechanosensory information processing allergy levels in mn quality aristocort 40 mg. Cutaneous and Subcutaneous Somatic Sensory Receptors the specialized sensory receptors in the cutaneous and subcutaneous tissues are dauntingly diverse (Table 8. They include free nerve endings in the skin, nerve endings associated with specializations that act as amplifiers or filters, and sensory terminals associated with specialized transducing cells that influence the ending by virtue of synapse-like contacts. Based on function, this variety of receptors can be divided into three groups: mechanoreceptors, nociceptors, and thermoceptors. On the basis of their morphology, the receptors near the body surface can also be divided into free and encapsulated types. Nociceptor and thermoceptor specializations are referred to as free nerve endings because the unmyelinated terminal branches of these neurons ramify widely in the upper regions of the dermis and epidermis (as well as in some deeper tissues); their role in pain and temperature sensation is discussed in Chapter 9. Most other cutaneous receptors show some degree of encapsulation, which helps determine the nature of the stimuli to which they respond. The A group is further broken down into subgroups designated a (the fastest), b, and d (the slowest). Changes in permeability generate a depolarizing current in the nerve ending, thus producing a receptor (or generator) potential that triggers action potentials, as described in Chapters 2 and 3. This overall process, in which the energy of a stimulus is converted into an electrical signal in the sensory neuron, is called sensory transduction and is the critical first step in all sensory processing. The quantity or strength of the stimulus is conveyed by the rate of action potential discharge triggered by the receptor potential (although this relationship is nonlinear and often quite complex). Some receptors fire rapidly when a stimulus is first presented and then fall silent in the presence of continued stimulation (which is to say they "adapt" to the stimulus), whereas others generate a sustained discharge in the presence of an ongoing stimulus (Figure 8. The usefulness of having some receptors that adapt quickly and others that do not is to provide information about both the dynamic and static qualities of a stimulus. Receptors that initially fire in the presence of a stimulus and then the Somatic Sensor y System 191 (A) Cerebrum Somatic sensory cortex Ventral posterior nuclear complex of thalamus Midbrain Figure 8. The first synapse is made by the terminals of the centrally projecting axons of dorsal root ganglion cells onto neurons in the brainstem nuclei (the local branches involved in segmental spinal reflexes are not shown here). The axons of these secondorder neurons synapse on third-order neurons of the ventral posterior nuclear complex of the thalamus, which in turn send their axons to the primary somatic sensory cortex (red). Information about pain and temperature takes a different course (shown in blue; the anterolateral system), and is discussed in the following chapter. Gracile nucleus Cuneate nucleus Medial leminiscus Medulla Dorsal root ganglion cells Mechanosensory afferent fiber Spinal cord Receptor endings Pain and temperature afferent fiber (B) Central sulcus Primary somatic sensory cortex 192 Chapter Eight Stimulus Slowly adapting Rapidly adapting become quiescent are particularly effective in conveying information about changes in the information the receptor reports; conversely, receptors that continue to fire convey information about the persistence of a stimulus. Accordingly, somatic sensory receptors and the neurons that give rise to them are usually classified into rapidly or slowly adapting types (see Table 8. Rapidly adapting, or phasic, receptors respond maximally but briefly to stimuli; their response decreases if the stimulus is maintained. Conversely, slowly adapting, or tonic, receptors keep firing as long as the stimulus is present. Mechanoreceptors Specialized to Receive Tactile Information 0 1 2 Time (s) 3 4 Figure 8. These functional differences allow the mechanoreceptors to provide information about both the static (via slowly adapting receptors) and dynamic (via rapidly adapting receptors) qualities of a stimulus. These receptors are referred to collectively as low-threshold (or high-sensitivity) mechanoreceptors because even weak mechanical stimulation of the skin induces them to produce action potentials. All low-threshold mechanoreceptors are innervated by relatively large myelinated axons (type A; see Table 8. The center of the capsule contains one or more afferent nerve fibers that generate rapidly adapting action potentials following minimal skin depression. Pacinian corpuscles are large encapsulated endings located in the subcutaneous tissue (and more deeply in interosseous membranes and mesenteries of the gut). The Pacinian corpuscle has an onion-like capsule in which the inner core of membrane lamellae is separated from an outer lamella by a fluid-filled space. These attributes suggest that Pacinian corpuscles are involved in the discrimination of fine surface textures or other moving stimuli that produce high-frequency vibration of the skin. In corroboration of this supposition, stimulation of Pacinian corpuscle afferent fibers in humans induces a sensation of vibration or tickle.

Visual Field Deficits A variety of retinal or more central pathologies that involve the primary visual pathway can cause visual field deficits that are limited to zyprexa allergy symptoms cheap aristocort 15 mg line particular regions of visual space allergy medicine and cold medicine order aristocort 10 mg free shipping. Because the spatial relationships in the retinas are maintained in central visual structures allergy medicine during first trimester cheap aristocort 40 mg on line, a careful analysis of the visual fields can often indicate the site of neurological damage penicillin allergy symptoms joint pain purchase 15mg aristocort visa. Relatively large visual field deficits are called anopsias and smaller ones are called scotomas (see Box A). The former term is combined with various prefixes to indicate the specific region of the visual field from which sight has been lost (Figures 11. Damage to the retina or one of the optic nerves before it reaches the chiasm results in a loss of vision that is limited to the eye of origin. In contrast, damage in the region of the optic chiasm-or more centrally-results in specific types of deficits that involve the visual fields of both eyes (Figure 11. Damage to structures that are central to the optic chiasm, including the optic tract, lateral geniculate nucleus, optic radiation, and visual cortex, results in deficits that are limited to the contralateral visual hemifield. For example, interruption of the optic tract on the right results in a loss of sight in the left visual field (that is, blindness in the temporal visual field of the left eye and the nasal visual field of the right eye). Because such damage affects corresponding parts of the visual field in each eye, there is a complete loss of vision in the affected region of the binocular visual field, and the deficit is referred to as a homonymous hemianopsia (in this case, a left homonymous hemianopsia). Those carrying information about the inferior portion of the visual field travel in the parietal lobe. The diagram on the left illustrates the basic organization of the primary visual pathway and indicates the location of various lesions. The right panels illustrate the visual field deficits associated with each lesion. In contrast, damage to the optic chiasm results in visual field deficits that involve noncorresponding parts of the visual field of each eye. For example, damage to the middle portion of the optic chiasm (which is often the result of pituitary tumors) can affect the fibers that are crossing from the nasal retina of each eye, leaving the uncrossed fibers from the temporal retinas intact. The resulting loss of vision is confined to the temporal visual field of each eye and is known as bitemporal hemianopsia. It is also called heteronomous hemianopsia to emphasize that the parts of the visual field that are lost in each eye do not overlap. Individuals with this condition are able to see in both left and right visual fields, provided both eyes are open. However, all information from the most peripheral parts of visual fields (which are seen only by the nasal retinas) is lost. As a result, the deficits associated with damage to the chiasm, optic tract, optic radiation, or visual cortex are typically more limited than those shown in Figure 11. This is especially true for damage along the optic radiation, which fans out under the temporal and parietal lobes in its course from the lateral geniculate nucleus to the striate cortex. More medial parts of the optic radiation, which pass under the cortex of the parietal lobe, carry information from the inferior portion of the contralateral visual field. Injury to central visual structures can also lead to a phenomenon called macular sparing, i. Macular sparing is commonly found with damage to the cortex, but can be a feature of damage anywhere along the length of the visual pathway. Although several explanations for macular sparing have been offered, including overlap in the pattern of crossed and uncrossed ganglion cells supplying central vision, the basis for this selective preservation is not clear. The Functional Organization of the Striate Cortex Much in the same way that Stephen Kuffler explored the response properties of individual retinal ganglion cells (see Chapter 10), David Hubel and Torsten Wiesel used microelectrode recordings to examine the properties of neurons in more central visual structures. The responses of neurons in the lateral geniculate nucleus were found to be remarkably similar to those in the retina, with a center-surround receptive field organization and selectivity for luminance increases or decreases. However, the small spots of light that were so effective at stimulating neurons in the retina and lateral geniculate nucleus were largely ineffective in visual cortex. By sampling the responses of a large number of single cells, Hubel and Weisel demonstrated that all edge orientations were roughly equally represented in visual cortex. As a (A) Experimental setup (B) Stimulus orientation Stimulus presented Light bar stimulus projected on screen Recording from visual cortex Record 0 1 2 Time (s) 3 Figure 11. Hubel and Wiesel also found that there are subtly different subtypes within a class of neurons that preferred the same orientation.

The scleral end of the rods is surrounded by processes that extend from the underlying pigment epithelial cells; the inner or vitreal end extends into the outer plexiform layer allergy shots itchy discount 10 mg aristocort amex. Each rod proper consists of outer and inner segments connected by a slender stalk containing nine peripheral doublets of microtubules allergy testing holding vials aristocort 15mg on-line. The doublets originate from a basal body in the vitreal end of the inner segment allergy treatment in dubai generic aristocort 15mg without a prescription, but the connecting stalk differs from a typical cilium in that it lacks a central pair of microtubules allergy medicine menstruation quality aristocort 40mg. The outer segment contains hundreds of flattened membranous sacs or discs of uniform diameter. After exposure to light, rhodopsin changes its molecular configuration from cis to trans and breaks down, resulting in hyperpolarization of the plasmalemma of the rod cell, with formation of an electrical potential that is transferred to dendrites of Fig. A diagrammatic sketch illustrating the basic threeneuron chain system of the retina. When stimulated by light, photoreceptor cells transmit an action potential to the bipolar neurons, which in turn synapse with ganglion cells. Unmyelinated axons from the ganglion cells enter the layer of retinal nerve fibers and unite at the optic disc to form the optic nerve, which transmits the impulse to the brain. Other intraretinal cells are either association neurons (horizontal cells, amacrine cells) or glial cells. Their cytoplasmic processes run between the cell bodies and processes of neurons in the retina and provide physical support for the neural elements. The inner segment consists of an outer scleral region called the ellipsoid (which contains numerous mitochondria) and a vitreal portion that houses the Golgi complex, free ribosomes, and myoid. The myoid region contains elements of granular and smooth endoplasmic reticulum and synthesizes and packages proteins that are transported down the connecting stalk to the scleral end of the outer rod segment to be used in the assembly of new membranous discs. Older sacs are shed from the tips of the rods during the morning hours and are replaced by new discs. The discarded discs are phagocytized and destroyed by cells of the pigment epithelium. The remainder of the rod cell consists of an outer fiber, a cell body, and an inner fiber (Fig. The outer fiber is a thin process that extends from the inner segment of the rod proper to the cell body, which contains the nucleus. The inner fiber joins the cell body to the spherule, a pear-shaped synaptic ending that contains numerous synaptic vesicles and a synaptic ribbon. The latter consists of a dense proteinaceous plaque that lies perpendicular to the presynaptic surface, often bounded by numerous vesicles. The cell body and nucleus of the rods are located in the outer nuclear layer of the retina; the spherule lies within the outer plexiform layer. In general, cone cells resemble the rods but are flask-shaped with short, conical outer segments and relatively broad inner segments united by a modified stalk similar to that of rod cells. The membranous sacs of the outer cone segments differ in that they may remain attached to the surrounding cell membrane and decrease in diameter as they approach the tip of the cone. The inner segment, also called the ellipsoid portion, shows a region with numerous mitochondria and a myoid part that contains the Golgi complex and elements of smooth and granular endoplasmic reticulum. As in rods, the cones synthesize proteins that pass to the outer segments, where they are used in the formation of new membranous sacs. Older sacs appear to be shed in the evening and are phagocytized in the pigment epithelial cells. Unlike those in rod cells, the sacs decrease in size as they approach the tip of the cone. The visual pigment of cone cells, iodopsin, is associated with the outer segments. Absorption of light and generation of an electrical impulse are similar to that occurring in rods. Cones function in color perception and visual acuity, responding to light of relatively high intensity. Detection of color is believed to depend on the presence of several pigments in the cones, whereas rods are thought to contain only one form of pigment.
