Introduction. Issues of studying the central origins and development of оccupational pathology in the faces of flight personnel define a need for the application of neurophysiological and neuropsychological methods of research. Material and methods. The levels of constant potential (LCP), characteristics the somatosensory caused potentials (SSVP), neuropsychological features in 95 patients with оccupational neurosensory deafness (ONSD) and 35 cases in a group of comparison are studied. Methods of the statistical analysis with a definition of W-of criterion of Shapiro-Uilka, Mann-Whitney›s U-criterion, coefficient of correlation of Spirmen, the discriminant analysis are applied. Results. in ONSD at patients the quantity of cases with the increased values of average LCP were established to prevail significantly in comparison with those in patients of a group of comparison (39% and 13% respectively, р = 0.03), strengthening of neuropower exchange in right and left frontal, central, left central, left parietal, right temporal assignments, increase in duration of the latent period of N18, N30 components are registered (р < 0.05). The condition of the cognitive sphere was characterized by the easily expressed violations of functions of analytical and synthetic thinking, оral-aural memory, visual, long-term memory, reciprocal coordination, impressive speech. Correlation connection between the index of N13-N20 and indices characterizing a condition of long-term memory, reciprocal coordination, the expressional speech is established (rs=0.45; 0.28; 0.28 at р =0.008; 0.04; 0.03 respectively), an index the between hemispheres of the relations Fd-Fs and latency of P25 and N30 (rs = 0.53 and 0.29 at р =0.009; 0.02 respectively). Diagnostic signs of brain deficiency at patients with ONSD were indices of visual gnosis, reciprocal coordination, LCP in right central, central parietal assignments of a brain, duration of the latent period of N30, N18-N20 (F=9.14; 5.43; 6.08; 4.41 4.77; 4.34 respectively). Conclusions. Violations of power metabolism in the frontal and central and parietal and temporal assignments of a brain, a functional condition of the central carrying-out structures, disorganization of cognitive activity were established to be a consequence of the impact of aviation noise and the reason of brain deficiency.

Visual working memory allows us to maintain information in mind for use in ongoing cognition. Research on visual working memory often characterizes it within the context of its interaction with long-term memory (LTM). These embedded-processes models describe memory representations as existing in three potential states: inactivated LTM, including all representations stored in LTM; activated LTM, latent representations that can quickly be brought into an active state due to contextual priming or recency; and the focus of attention, an active but sharply limited state in which only a small number of items can be represented simultaneously. This chapter extends the embedded-processes framework of working memory. It proposes that working memory should be defined operationally based on neural activity. By defining working memory in this way, the important theoretical distinction between working memory and LTM is maintained, while still acknowledging that they operate together. It is additionally proposed that active working memory should be further subdivided into at least two subcomponent processes that index item-based storage and currently prioritized spatial locations. This fractionation of working memory is based on recent research that has found that the maintenance of information distinctly relies on item-based representations as well as prioritization of spatial locations. It is hoped that this updated framework of the definition of working memory within the embedded-processes model provides further traction for understanding how we maintain information in mind.

Encoding And Retrieval

Long-term memory (LTM) is one of the diverse cognitive functions adversely affected by multiple sclerosis (MS). The LTM deficits have often been attributed to failure of retrieval, whereas encoding processes are presumed intact. However, support for this view comes primarily from studies in which encoding and retrieval operations were not investigated systematically. In the current study, we used an encoding specificity paradigm to examine the robustness of encoding in MS and to specifically evaluate the impact of the disease on contextual memory. We hypothesized that persons with MS would exhibit a selective impairment in retrieving items from LTM when required to generate new cue-target associations at encoding, but not when cues held a strong preexisting relationship to the targets. The findings supported the hypotheses. We conclude that the mnemonic deficits associated with MS affect both encoding and retrieval. Specifically, problems with binding of contextual information at encoding impair effective retrieval of memories. Nonetheless, access to these memories can be gained through preexisting associations organized in the semantic network. (JINS, 2002, 8, 395–409.)

Definition Of

Under various circumstances and in different species the outward expression of learning varies considerably, and this has led to the classification of different categories of learning. Just as there is no generally agreed on definition of learning, there is no one system of classification. Types of learning commonly recognized are: Habituation, sensitization, classical conditioning, operant conditioning, trial and error, taste aversion, latent learning, cultural learning, imprinting, insight learning, learning-set learning and instinct. The term memory must include at least two separate processes. It must involve, on the one hand, that of learning something and on the other, at some later date, recalling that thing. What lies between the learning and (he remembering must be some permanent record — a memory trace — within the brain. Memory exists in at least two forms: memory for very recent events (short-term) which is relatively labile and easily disruptable; and long-term memory, which is much more stable. Not everything that gets into short-term memory becomes fixed in the long-term store; a filtering mechanism selects things that might be important and discards the rest.
