The Way

In this article, a practical look is taken at some of the possible enhancements for humans through the use of implants, particularly into the brain or nervous system. Some cognitive enhancements may not turn out to be practically useful, whereas others may turn out to be mere steps on the way to the construction of superhumans. The emphasis here is the focus on enhancements that take such recipients beyond the human norm rather than any implantations employed merely for therapy. This is divided into what we know has already been tried and tested and what remains at this time as more speculative. Five examples from the author’s own experimentation are described. Each case is looked at in detail, from the inside, to give a unique personal experience. The premise is that humans are essentially their brains and that bodies serve as interfaces between brains and the environment. The possibility of building an Interplanetary Creature, having an intelligence and possibly a consciousness of its own, is also considered.

The Brain

The human mind is the mediator of knowledge about the world because no human being has direct knowledge of their surrounding reality. All knowledge is „read and transported” by the brain and nervous system. Regardless of the progressive nature of the research into psychic phenomena, we are still faced with the mystery of what phenomena occur in the brain. The difficulties are mainly due to the interdisciplinary nature of cognitive science. Cognitive science as an interdisciplinary field, which attempts to explore the human mind and find a common area of research to unite all scientific research. Attempts to understand the mind constitute the most interdisciplinary task. Neuroscience is one of the disciplines that make up modern cognitive science. Neurobiology suggests the variety of processes that occur either in individual cells, the brain, and the nervous system, and the human body. Modern studies indicate the possibility of cognition of the brain in order to apply effective teaching and education. How does the brain learn? This question stimulates researchers to interdisciplinary cooperation in order to obtain a satisfactory answer. Recently there have been many new concepts related to research into the brain and methods that allow you to better utilize the potential of the brain in order to undertake a conscious process of self-discovery. The science of the brain is not only a part of medical science or biology but also disciplines such as pedagogy and didactics. The concepts neuroteaching, neurodidactics, and neurotechnologies are new, still relatively unknown, and unused. Reflecting on the conscious changes in the learning process, it is worth looking into the rules of biofeedback and neurofeedback and the possibilities of practically applying EEG biofeedback training, which is becoming a readily available method. Insightful observations of bioelectrical activity of the brain have led to naming multiple correlations between the mental state of individuals, their behavior, and EEG activity. Biofeedback, as a neurotechnological road to self-discovery, allows for the individual functions of the brain and body, previously considered involuntary, to become dependent on our will to a certain degree. Upon obtaining a higher degree of self-awareness, self-regulatory responses develop. Proponents of this method argue that self-regulation will become a major part of health care in the twenty-first century.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Ocellar Nerve

Barnacles are very specialized Crustacea, with strongly reduced head and abdomen. Their nervous system is rather simple: the brain or supra-oesophageal ganglion (SG) is a small bilobed structure and the toracic ganglia are fused into a single ventral mass, the suboesophageal ganglion (VG). Neurosecretion was shown in barnacle nervous system by histochemical methods and numerous putative hormonal substances were extracted and tested. Recently six different types of dense-core granules were visualized in the median ocellar nerve of Balanus hameri and serotonin and FMRF-amide like substances were immunocytochemically detected in the nervous system of Balanus amphitrite. The aim of the present work is to localize and characterize at ultrastructural level, neurosecretory neuron cell bodies in the VG of Balanus amphitrite.Specimens of Balanus amphitrite were collected in the port of Genova. The central nervous system were Karnovsky fixed, osmium postfixed, ethanol dehydrated and Durcupan ACM embedded. Ultrathin sections were stained with uranyl acetate and lead citrate. Ultrastructural observations were made on a Philips M 202 and Zeiss 109 T electron microscopy.

Abstract Complex trauma resulting from chronic maltreatment and prenatal alcohol exposure can significantly affect child development and academic outcomes. Children with histories of maltreatment and those with prenatal alcohol exposure exhibit remarkably similar central nervous system impairments. In this article, I will review the effects of each on the brain and discuss clinical implications for these populations of children.

Abstract Injuries that affect the central nervous system (CNS) can be catastrophic because they involve the brain or spinal cord, and determining the underlying clinical cause of impairment is essential in using the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), in part because the AMA Guides addresses neurological impairment in several chapters. Unlike the musculoskeletal chapters, Chapter 13, The Central and Peripheral Nervous System, does not use grades, grade modifiers, and a net adjustment formula; rather the chapter uses an approach that is similar to that in prior editions of the AMA Guides. The following steps can be used to perform a CNS rating: 1) evaluate all four major categories of cerebral impairment, and choose the one that is most severe; 2) rate the single most severe cerebral impairment of the four major categories; 3) rate all other impairments that are due to neurogenic problems; and 4) combine the rating of the single most severe category of cerebral impairment with the ratings of all other impairments. Because some neurological dysfunctions are rated elsewhere in the AMA Guides, Sixth Edition, the evaluator may consult Table 13-1 to verify the appropriate chapter to use.

The review is an attempt to describe and give a meaning to the accumulated data about the mechanisms controlling the structure and functionality of the postural muscle the almost continuous work of which makes it possible for the humans and animals to exist actively on Earth's surface. A great bulk of these data was obtained, described and systematized by professor I.B. Kozlovskaya and her pupils. A body of the most interesting facts and regularities was documented in other laboratories and research centers, quite often under the influence of ideas suggested by I.B. Kozlovskaya. The concept of the tonic system, that is, an integral physiological apparatus comprising not only slow and fast muscular fibers and small controlling motoneurons but also a complex of the brain (up to and including the striatum and motor cortex) and sensory mechanisms, constitutes the most important parts of her theoretical legacy. The fundamental conclusion of this review is that the gravity-dependent tonic contracting activity of the postural muscle controlled by the nervous system and afferent mechanisms is key to maintaining its structure, signal pathways and mechanic properties crucial for its constant anti-gravity activity.

Background: The Renin-Angiotensin System (RAS) is a key regulator of cardiovascular and renal homeostasis, but also plays important roles in mediating physiological functions in the central nervous system (CNS). The effects of the RAS were classically described as mediated by angiotensin (Ang) II via angiotensin type 1 (AT1) receptors. However, another arm of the RAS formed by the angiotensin converting enzyme 2 (ACE2), Ang-(1-7) and the Mas receptor has been a matter of investigation due to its important physiological roles, usually counterbalancing the classical effects exerted by Ang II. Objective: We aim to provide an overview of effects elicited by the RAS, especially Ang-(1-7), in the brain. We also aim to discuss the therapeutic potential for neuropsychiatric disorders for the modulation of RAS. Method: We carried out an extensive literature search in PubMed central. Results: Within the brain, Ang-(1-7) contributes to the regulation of blood pressure by acting at regions that control cardiovascular functions. In contrast with Ang II, Ang-(1-7) improves baroreflex sensitivity and plays an inhibitory role in hypothalamic noradrenergic neurotransmission. Ang-(1-7) not only exerts effects related to blood pressure regulation, but also acts as a neuroprotective component of the RAS, for instance, by reducing cerebral infarct size, inflammation, oxidative stress and neuronal apoptosis. Conclusion: Pre-clinical evidence supports a relevant role for ACE2/Ang-(1-7)/Mas receptor axis in several neuropsychiatric conditions, including stress-related and mood disorders, cerebrovascular ischemic and hemorrhagic lesions and neurodegenerative diseases. However, very few data are available regarding the ACE2/Ang-(1-7)/Mas receptor axis in human CNS.

Introduction: The infiltration of HIV into the brain alters the functions of the nervous system known as NeuroAIDS. It leads to neuronal defects clinically manifested by motor and cognitive dysfunctions. Materials/Methods: Current antiretroviral therapy can prevent viral replication but cannot cure the disease completely. HAART-Highly active antiretroviral therapy used for the treatment of HIV infection. Challenges in neuro-AIDS therapy are as shown in the graphical abstract. One of the challenges is latent viral reservoirs like the brain; which acts as a sanctuary site for viruses. Nearly ~50% of HIV patients show neuropathological signs. Nervous system related disorders including AIDS dementia, sensory neuropathy, and myelopathy have a 25% of prevalence in patients having access to a highly active combination antiretroviral therapy. Results/Conclusions: Brain is one of the viral sanctuary sites for HIV. The current need of neuro-AIDS therapy is to target the brain as a viral reservoir. Drugs should cross or bypass the blood-brain barrier to reach the brain with effective concentrations. Current research on novel drug delivery approaches may prove helpful to treat neuro-AIDS and related disorders effectively.
