Most of us have five senses that our brains use to create a model of the world us. We see, hear, smell, taste, and touch our way around. If one of your senses is not working properly, your brain fills in the gaps by paying more attention to the other senses. However, your other senses cannot always fill in the gaps. If your ears are not working, your eyes alone may not be able to tell your brain that an out-of-control car is screeching toward you! But what if we could help the brain fill in the gaps by purposefully sending the missing information through another sense? What if you could “hear” where a sound is through your sense of touch? This article will explain how people were able to do just that, using wristbands that converted sound into vibration.

Diminizene aceturate (DA) is the drug of choice for treating Canine Trypanosomosis and Canine Babesiosis in many countries of the world. However, co-administration of the drug with long acting Oxytetracycline (OXY-LA) has been associated with nervous signs suggestive of its toxicity, in treated dogs, even at the normal dose. To investigate what causes this toxicity, fourteen Nigerian indigenous dogs were randomly selected into two groups that comprised six dogs each and the remaining untreated two dogs were used for preparation of tissue standards. One group was treated with DA (3.5mg/kg) alone while the other was, additionally, treated with OXY-LA, 10 minutes post treatment (PT) with DA. Two dogs from each group were sacrificed at 240, 360 and 480 hours, PT and their livers, brains, kidneys, hearts and skeletal muscles were harvested and assayed for DA. Mean DA-concentrations in brains of the DA-OXY-LA group (19.71± 1.31a; 15.86± 2.96a; 9.11± 3.31a) were higher (P≤ 0.05) than 1.39 ± 0.45b; 1.05± 0.29b; 0.71 ± 0.30b of the DA-alone group at 240, 360 and 480 hours, PT, respectively. Also, mean-DA concentration in kidneys (8.00 ±0.46a) of the DA-OXY-LA group was significantly (P≤ 0.05) higher than 3.76±0.32b of the DA-alone group at 360 hours PT. These results suggest that OXY-LA enhances DA-accumulation in the brain and reduces its kidney-elimination, thus making the normal dose to act as overdose, which causes the nervous signs often manifested by treated dogs.

Straipsnis analizuoja Edmundo Husserlio, Jeano-Paulo Sartre’o ir Maurise Merleau-Ponty požiūrį į kūno vaidmenį intersubjektyviuose santykiuose. Jeanas-Paulas Sartre’as atmeta dvigubų jutimų sampratą. Jis neigia galimybę patirti kūną kaip subjektą ir objektą vienu metu. Sartre’as akcentuoja, kad kitas vizualiai pažįstamas tik jį paverčiant objektu. Edmundas Husserlis ir Maurise Merleau-Ponty ieško sąryšio su kitu kūniškumo plotmėje. Atrasdami prisilietimo grįžtamąjį ryšį su savimi, o vėliau išplėtodami šią kvazirefleksijos sampratą ir kitų juslių lygmeniu, Husserlis ir Merleau-Ponty sugriauna tradicinę sąmonės ir savasties sampratą. Sąmonė nebegali būti suprantama kaip vidujybė, o kūnas kaip išorybė. Pats kūnas atrandamas kaip susidvejinęs – patiriantis kitą ir save tuo pat metu. Suskyla ir savasties substanciškumas. Savastis visada pasirodo kitame, kitam ir per kitą. Kartu pasikeičia ir santykio su kitu traktuotė. Kitas nėra kažkoks transcendentiškas objektas, kurį reikia pažinti ar užvaldyti. Santykis su kitu atsiskleidžia kartu kaip santykis su savimi ir santykis su pasauliu. Jei mano kūnas nėra vien mano kūnas, bet jis yra tarp manęs ir kitų, tai tada galime suvokti, kodėl aš negaliu savęs sutapatinti su vieta, kurioje esu. Ir mano vieta, kaip ir mano kūnas, yra mano tiktai kitų atžvilgiu. Mano savastį iš esmės apibrėžia šis tarpkūniškumas, kurio patirtis sudaro sąlygas ne tik įsisąmoninti savąjį socialumą, bet ir suvokti savosios būties tarp – pasauliškumą. Pagrindiniai žodžiai: fenomenologija, intersubjektyvumas, kitas, gyvenamas kūnas, tarpkūniškumas, savipatirtis.   Phenomenology of Intersubjective Body: the Experience of TouchDalius Jonku  Summary The article deals with the conception of intersubjective body in Edmund Husserl’s, Jean-Paul Sartre’s and Maurice Merleau-Ponty philosophy. Jean-Paul Sartre rejects the conception of double sense, i.e. he denies the possibility to have bodily experience as a subject and an object at the same time. He argues that we can know Other visually only as an object. Husserl and Merleau-Ponty are in search of connection with the Other on a new plane. They investigate the preconditions of the openness to the Other. Their attention is focused on the bodily self-awareness in the experience of touch. Both philosophers develop the conception of bodily quasi-reflection. They transform the traditional conception of selfhood and show its paradoxical alienation from itself. The one’s own body is revealed as insisting on the otherness. The analysis of double senses in the experience of the sense of touch reveals the experience of “my” body as an inter-corporality. That’s because both philosophers can reject the prejudice of immanence and transcendence. The experience of a living body is always a relation with “myself”, with the other and with the world. Keywords: phenomenology, intersubjectivity, interreflectivity, Other, living body, self-awareness.ibri, sans-serif; font-size: 15px; line-height: 17px;">

Objective: to evaluate the memory phenomenon when synchronizing an area of the brain interacting with the external environment. Introduction: Dr. Dale Bredesen estimates that there will be more than 160 million individuals with Alzheimer’s dementia in the world by 2050. Amnesia in temporal lobe epilepsy indicates that the hyperactive excitability generated in this temporal lobe impairs the ability to memorize, destabilizing the rhythm in relative to the other brain lobes. Methodology: through literature review it is assessed that there is a working relationship between the region on the cortical side of the brain and the contralateral homotopic cortex. Results and discussion: the types of amnesia are classified in a first group whose organic causes predominate. We must not forget the danger of the accumulation of non-functional proteins that can precede the formation of beta-amyloid aggregates. They replicate more intensely than an infectious agent does, because they do not need genetic material for their multiplication. Conclusion: the first group may also be due to the lack of memory consolidation (sleep disorders, lack of mnemic exercise, malnutrition, infection or other conditions). There is a second group whose psychological causes predominate. Studies on the hormone DHEA (dehydroepiandrosterone) can help improve these neurodegenerative processes.

Abstract Background Minimally invasive intracerebral hemorrhage (ICH) evacuation has gained popularity with success in early-phase clinical trials. This procedure, however, is performed in very different ways around the world. Objective To provide a technical description of these strategies that facilitates comparison and aids decisions in which surgery to perform, and to inform further improvements in minimally invasive ICH evacuation. Methods Major authors of clinical trials evaluating each of the main techniques were contacted and asked to supply a case example and technical description of their respective surgeries. Results Five major techniques are presented including stereotactic thrombolysis, craniopuncture, endoscopic, endoscope-assisted, and endoport-mediated. Techniques differ in numerous ways including the size of the cranial access, the size of the access corridor through the brain to the hematoma, and the evacuation strategy. Regarding cranial access, a burr hole is created in stereotactic thrombolysis and craniopuncture, a small craniectomy in endoscopic, and a small craniotomy in the other 2. Access corridors through the parenchyma range from 3 mm in craniopuncture to 13.5 mm in the endoport-mediated evacuation. Regarding evacuation strategies, stereotactic thrombolysis and craniopuncture rely on passive drainage from a catheter placed during surgery that remains in place for multiple days, while the other 3 techniques rely on active evacuation with suction and bipolar cautery. Conclusion Future comparative clinical trials may identify the advantageous components of each strategy and contribute to improved outcomes in this patient population.

One of the main activities of the brain is the recognition of signals. As it was pointed out in [22, 25] the procedure of recognition can be described as follows: There is a set of complex signals stored in the memory. Choosing one of these signals may be interpreted as generating a hypothesis concerning an "expected view of the world". Then the brain compares a signal arising from our senses with the signal chosen from the memory. That changes the state of both signals in such a manner that after the procedure the signals coincide in a certain sense. Furthermore, measurements of that procedure like EEG or MEG are based on the fact that recognition of signals causes a certain loss of excited neurons, i.e. the neurons change their state from "excited" to "nonexcited". For that reason a statistical model of the recognition process should reflect both — the change of the signals and the loss of excited neurons. Now, [5] represents the first attempt to explain the process of recognition in terms of quantum statistics. According to the general conception of quantum theory, the procedure of recognition should be described by an operator on a certain Hilbert space. In [5] we proposed two candidates for such an operator. One of them reflects in a clear sense the mentioned change of the signals. The other one reflects the loss of excited neurons. We will prove (cf. Theorem 4) that for sufficiently high intensities of the signals both operators are approximately equal.

Discusses the role that attention plays in constituting the world, rather than reducing phenomena to the brain level. Discusses the different kinds of attention delineated by the divided hemispheres of the brain. On the one hand the left hemisphere specialised in grasping and manipulating the world, whereas the right hemisphere specialises in relat-ing to and understanding the world. Discusses how reliance on one or the other kind of attention has cultural, psychological and social implications.

This chapter introduces two interpretations of how we know about the world. One, the standard, sensory-to-motor view, is that physical actions for sounds, lights, tastes, smells, and so on act on our sense organs to produce messages that are sent through the nervous system to the cerebral cortex, where the relevant structures of the world can be recognized and appropriate motor actions can be initiated. The other is an interactive sensorimotor view where the nervous system records our interactions with the world, abstracting our knowledge about the world from these interactions. These two opposing views have rarely been considered in terms of specific neural pathways or the messages that they carry; that is the plan for this book. Each view leads to different sets of interpretations of experiments and to different sets of research proposals. The final part of the chapter explores a well-studied and widely taught clinical condition that illustrates the confusions that can arise when the dual meaning of the driver messages to the thalamus is not recognized.

It is widely acknowledged that, in order to provide a rich unified experience to our internal conscious observer, the brain constructs a sophisticated model of the world on the basis of fragmented pieces of information incoming from sensory organs. It has been long known that perceptual filling-in mechanisms exist to extrapolate missing information from adjacent visual fields, especially in the periphery. Recently, a uniformity illusion has been reported for primitive features, such as color, shape and motion, in which the content of central vision spreads to the periphery upon prolonged gaze fixation. Here I report that similar illusion exists for real-world textures, such as grass and foliage, observed directly in a real environment or on a photographic image. The texture around the point of gaze fixation is perceptually cloned to cover the areas of similar texture and color. This illusion may be triggered by the fading of textural information in the periphery due to the Troxler effect. This is a preliminary report and requires validation in multiple subjects and detailed characterization.

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.

The main objective of this study is the substantiation of experiment as one of the key features of the world music in Ukraine. Based on the creative works of the brightest world music representatives in Ukraine, «Dakha Brakha» band, the experiment is regarded as a kind of creative setting. Methodology and scientific approaches. The methodology was based on the music practice theory by T. Cherednychenko. The author distinguishes four binary oppositions, which can describe the musical practice. According to one of these oppositions («observance of the canon or violation of the canon»), the musical practices, to which the Ukrainian musicology usually classifies the world music («folk music» and «minstrel music»), are compared with the creative work of «Dakha Brakha» band. Study findings. A lack of the setting to experiment in the musical practices of the «folk music» and «minstrel music» separates the world music musical practice from them. Therefore, the world music is a separate type of musical practice in which the experiment is crucial. The study analyzed several scientific articles of Ukrainian musicologists on the world music; examined the history of the Ukrainian «Dakha Brakha» band; presented a list of the folk songs used in the fifth album «The Road» by «Dakha Brakha» band; and showed the degree of the source transformation by musicians based on the example of the «Monk» song. The study findings can be used to form a comprehensive understanding of the world music musical practice. The further studies may be related to clarification of the other parameters of the world music musical practice, and to determination of the experiment role in creative works of the other world music representatives, both Ukrainian and foreign. The practical study value is the ability to use its key provisions in the course of modern music in higher artistic schools of Ukraine. Originality / value. So far, the Ukrainian musicology did not consider the experiment role as the key one in the world music.
