In daily life, humans can not be separated from the name of learning and remembering. Learning and remembering is the basis for someone to adapt their behavior to the environment. The brain is the organ that regulates learning and memory. The brain will store and bring back the information needed. Decline in memory usually occurs during old age but does not rule out the possibility of happening at a young age too. Decreasing memory recall at a young age is usually caused by a lack of physical activity. Sports is one of the factors that can improve memory. Exercise can improve blood circulation so that the brain can be well-nourished and will work optimally. To make our memories into long-term memories can be done by repeating the information obtained. Because repetition can accelerate and increase consolidation. Information entered in long-term memory will be grouped according to the type of information. This grouping serves to facilitate the search for the desired information. Short-term information will forever be forgotten, but long-term information can last up to a lifetime.

It is attempted in this paper to give a mathematical description of the short-term memory. Instead of using the microscopic properties of individual neu rons, such as the number of interconnections, neuron density, threshold value, etc., the cerebral cortex is regarded as a "neuron gas" that is a vast conglomer ate of neurons with statistically distributed charac teristics. Stimuli from the environment cause the receptor neurons to emit virtual electromagnetic waves into the brain. A self-optimizing process of the brain tis sue is here described by which the useful, informa tion-carrying energy reaching the long-term memory tends to maximum. It is emphasized that in the following a brain model is described and the physical processes in volved may have no direct equivalent in reality.

We challenge Ruchkin et al.'s claim in reducing short-term memory (STM) to the active part of long-term memory (LTM), by showing that their data cannot rule out the possibility that activation of posterior brain regions could also reflect the contribution of a verbal STM buffer.

Different Parts

In this paper, various types of memory are considered.Development of the nervous system and the brain of organisms ensures expansion of species with more developed brain. Different characteristics of the brain zones have created different conditions for forming traces of events. The various traces of trace events formed in different parts of the brain provided a wider range of functions and brain responses, which contributed to the survival and expansion of species. The work describes the appearance of memory varieties and the causes of these varieties.

The concept of the neuromatrix assumes that all behaviours are associated with complex spatiotemporal electromagnetic fields within the brain. The same complex magnetic field can be supported potentially by different mosaics of neuronal associations and result in the same behaviours. In the present study the accuracy of long-term and short-term spatial memory for rats that had been treated with 100 mg/kg of ketamine immediately after the induction of seizures by lithium and pilocarpine did not differ from normal rats despite the conspicuous multifocal neuronal loss. A 30-min. delay of treatment with ketamine resulted in significant memory impairment. Whereas deficits in short-term memory were significantly correlated with cell loss within the CA field of the hippocampus, deficits in long-term memory were related to cell loss within specific thalamic-amygdaloid structures. Implications for the concept of the neuromatrix, if valid, are discussed.

Studies of neuropsychological patients are relevant to models of how long-term memories are stored. If amnesia is considered a binding deficit and not a difficulty in transferring information from short-term to long-term memory, it is unclear why context-free semantic learning is impaired. Also the model should account for the reverse temporal gradient seen in patients with semantic dementia.

The role of phosphatidylserine in providing the cognitive functions of the brain is considered. The Neuroexel complex, which contains phosphatidylserine and alpha-lipoic acid, can reduce cognitive imbalance caused by atherosclerotic changes, improve short-term and long-term memory. The use of a dietary supplement, which includes phosphatidylserine, can improve the adaptive potential of a person.

Abstract Background and Aims Chronic kidney disease (CKD) is getting prevalent and causes big burden to the health care systems worldwide. CKD-associated cognitive impairment (CI) not only influences the behave function, but also results in longer hospitalization and higher risk of mortality. Inflammation is an important pathogenesis of CKD and plays a crucial role in progression of CKD. In this study, we hypothesized that accumulated uremic toxins, especially indoxyl sulfate (IS) and P-cresyl sulfate (PCS) induce neuroinflammation via activation of NLRP3 inflammasome in the brain tissue of CKD animals. This study aims to delineate the crosstalk between uremic toxins and inflammation in CKD-induced CI. Method Eight-week-old male C57B6 wildtype and NLRP3 knockout mice received sham and 5/6 nephrectomy to mimic CKD status. AST-120 (Kremezin), a spherical carbon adsorbent, was given orally to mice to neutralize the accumulated uremic toxins. The Y-maze and Morris water maze (MWM) testes were applied to evaluate cognitive function, including the spatial, short-term and long-term memory in shame, CKD, and AST-120 treated CKD mice. HPLC was used to examine the concentration of IS and PCS in the serum and brain tissues. Western blot and immunohistochemistry stain were used to identify the protein expression of target molecules in the brain tissue. Results CKD mice showed impaired spatial, short-term and long-term memory; however, 10% AST-120 attenuated CKD-induced memory impairment (Figure 1). IS, but not PCS, elevated in the brain tissues, especially in the frontal cortex and hippocampus. AST-120 reduced CKD-induced IS elevation in the brain tissue, and also ameliorated NLRP3 inflammasome activation in the astrocytes in the frontal and hippocampus. Finally, NLRP3 deficiency reversed the CKD-induced memory impairment (Figure 2). Conclusion IS is the major uremic toxin that causes CI in CKD mice via activating NLRP3 inflammasome pathway in the brain tissue. However, AST-120 effectively ameliorates CKD-induced CI.

Use Of Knowledge

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Speed And Accuracy

Objectives School-age children with and without parent-reported listening difficulties (LiD) were compared on auditory processing, language, memory, and attention abilities. The objective was to extend what is known so far in the literature about children with LiD by using multiple measures and selective novel measures across the above areas. Design Twenty-six children who were reported by their parents as having LiD and 26 age-matched typically developing children completed clinical tests of auditory processing and multiple measures of language, attention, and memory. All children had normal-range pure-tone hearing thresholds bilaterally. Group differences were examined. Results In addition to significantly poorer speech-perception-in-noise scores, children with LiD had reduced speed and accuracy of word retrieval from long-term memory, poorer short-term memory, sentence recall, and inferencing ability. Statistically significant group differences were of moderate effect size; however, standard test scores of children with LiD were not clinically poor. No statistically significant group differences were observed in attention, working memory capacity, vocabulary, and nonverbal IQ. Conclusions Mild signal-to-noise ratio loss, as reflected by the group mean of children with LiD, supported the children's functional listening problems. In addition, children's relative weakness in select areas of language performance, short-term memory, and long-term memory lexical retrieval speed and accuracy added to previous research on evidence-based areas that need to be evaluated in children with LiD who almost always have heterogenous profiles. Importantly, the functional difficulties faced by children with LiD in relation to their test results indicated, to some extent, that commonly used assessments may not be adequately capturing the children's listening challenges.
