SUMMARY We outline a systematic approach to investigating the role of modular map-like cortical organization in the processing of sensory information. We survey current evidence concerning the functional signiﬁcance of cortical maps and modules, argu- ing that the topographic framework of primary sensory cortex renders the encoding and storage of sensory information efﬁcient, fast, and reliable. Neuronal populations in sensory cortex exhibit ﬂuctuations in excitability, charac- terized by bursts of spikes synchronized across barrel cortex. By comparing the plasticity induced by sensory inputs delivered during bursts compared to those delivered between bursts, we discovered that the strength of co-activity between columns in the barrel cortex can be modiﬁed by sensory input patterns during discrete, intermittent intervals time-locked to bursts. These spatial and temporal rules provide a context for understanding the barrel cortex in an awake exploring rat. RAT VIBRISSAL SENSORY PATHWAY AS A GENERAL MODEL We will review a series of experiments carried out in laboratory rats and, in a few cases, in human subjects. Indeed, as nocturnal animals, albino rats depend on their vibrissal sensory system for object localization, judgment of the roughness or texture of surfaces, and the size and shape of small objects. It is of particular interest that humans and rats have roughly equivalent capacities in texture discrimination,1 the haptic task that can be most directly compared between species. We believe that insights into its functioning will generalize to other specialized systems like the primate visual system. Rather than passively allowing objects to encounter the whisker, the rat sweeps its whiskers backwards and forwards through the air, seeking out things. As the whisker is a specialized hair, the transduction process occurs within the whisker follicle. The neural pathway begins at the primary afferent terminations resting on the whisker shaft.
Drusen—Fatty deposits that can accumulate Genetic profile underneath the retina and macula purchase 40 mg aristocort overnight delivery, and sometimes AMD is considered to be a complex disorder aristocort 15 mg visa, likely lead to age-related macular degeneration (AMD). This type of disorder is caused by multifactorial cells, which causes central and color vision prob- inheritance, which means that many factors likely inter- lems for people with dry AMD. As Genetic heterogeneity—The occurrence of the implied by the words “age-related”, the aging process is same or similar disease, caused by different genes one of the strongest risk factors for developing AMD. Multifactorial inheritance—A type of inheritance pattern where many factors, both genetic and Genetic factors environmental, contribute to the cause. Determining the role that genetic factors play in the Optic nerve—A bundle of nerve fibers that carries development of AMD is a complicated task for scientists. In addition, although AMD seems to Peripheral vision—The ability to see objects that run in families, there is no clear inheritance pattern are not located directly in front of the eye. However, many studies have supported the located on the side or edge of their field of vision. There are two types of photore- ditions like AMD is to study genes that cause similar con- ceptor cells: rod cells and cone cells. Cone cells identify changes (mutations) in the ATP-binding cassette are responsible for perceiving color and for central transporter, retina-specific (ABCR) gene in people diag- vision. The process began after genetic research identified changes in the ABCR gene among Retina—The light-sensitive layer of tissue in the people with an autosomal recessive macular disease back of the eye that receives and transmits visual called Stargardt macular dystrophy. However, the researchers who found mutations in the ABCR gene • Light skin and eye color among people with AMD located only one allele with a However, not all studies have found a strong rela- mutation, which likely created an increased susceptibility tionship between these factors and AMD. They concluded that people with an ABCR research is needed to decipher the role that both genetic gene mutation in one allele could have an increased and environmental factors play in the development of this chance to develop AMD during their lifetime if they also complex condition. Other scientists tried Environmental factors to repeat this type of genetic research among people with Determining the role that environmental factors play AMD in 1999, and were not able to confirm that the in the development of AMD is an important goal for ABCR gene is a strong genetic risk factor for this condi- researchers. However, it is possible that the differing research trolled, people can often find motivation to change their results may have been caused by different research meth- behaviors if they are informed about environmental risk ods, and further studies will be necessary to understand factors that may be within their control. Unfortunately, the importance of ABCR gene mutations in the develop- identifying environmental factors that clearly increase (or ment of susceptibility to AMD. Several In 1998, another genetic researcher reported a fam- potential risk factors have been studied. These include: ily in which a unique form of AMD was passed from one generation to the next. An affected person with an auto- strong associations between these factors and the devel- somal dominant condition thus has one allele with a opment of AMD.
