Man is distinguished from all other living creatures by the quality and range of his intellect, and on the physical side by the nature of the brain which confers upon him this mental pre-eminence. Moreover, as its exceptional powers were acquired by a process of evolution, the true significance of the human attributes can only be appreciated by examining the history of their development.

This introductory chapter begins by providing an overview of the power of the human brain, which is displayed in the wonders of modern civilization. Despite the human brain’s capacity for such intellectual and technological feats, we still know astonishingly little about how it achieves them. This deficit in understanding is a problem not only because it means we lack basic knowledge of the biological factors that underlie our human uniqueness, but also because, for all its amazing capabilities, the human mind seems particularly prone to dysfunction. Still, some would argue there is good reason to be optimistic about the prospect of developing new and better treatments for mental disorders in the not-so-distant future. Such optimism is based on the increasing potential to study how the brain works in various important new ways thanks to recent technological innovations. The chapter then considers two overly polarised views of the human mind. Ultimately, this book argues that society radically restructures the human brain within an individual person’s lifetime, and that it has also played a central role in the past history of our species, by shaping brain evolution.

Abstract: People have been taking the drug in various forms for many years for enjoyment, relaxation, sleeping, stimulation, or another reason. In the starting, people takes the drug for taste and alter the consciousness, behavior, mood, and thoughts but he/she becomes habitual and dependent on any substance use disorder such as alcohol, tobacco, cannabis, ecstasy, cocaine, methamphetamine, and heroin, amphetamines, or illegal drugs. As per my thoughts and watching surroundings, if you ask a drug intake person “how do you become a drug addictive”? Most people will answer this “they started taking the drug in their friend circle, at relatives home or with relationship partner”. The first time they take it for taste or due to forcing by someone but after some time this becomes a habit. Peer pressure can fall you in this black world. Also, if someone has family history of addiction then he/she may chance to catch this addiction and make habitual others as well. So good friend circle really matters. Drugs such as heroin and marijuana are structured in the same way as chemical messengers known as neurotransmitters. These neurotransmitters are produced naturally by the human brain. As a result of this similarity, the drugs can fool the receptors of human brain and activate the nerve cells in such a way that they send some abnormal messages. In case of drugs like methamphetamine and cocaine, the nerve cells get activated and they release extraordinarily large volumes of neurotransmitters. They are also capable of preventing the brain from recycling these chemicals in a normal manner. A normal level of production is necessary in order to end the signal between neurons.

Purpose of the study:This study is an academic response to a long debate about the practice of zikrullah in the community in order to get answers scientifically. Methodology:The author uses combined data in this study, qualitative data to find models of zikrullah and quantitative data through Electro Encephalo Graf to see the mechanisms and effects of zikrullah on the human brain. Main Findings: The results of the study show that in zikrullah there are five main aspects, namely the aspect of breathing as a mechanism for gas exchange for metabolism in the body, the voiceless aspect as the process of presenting zikrullah energy which will be transmitted to the brain, aspects of hearing to accelerate the presence of alpha waves, aspects of remembering as mental processes affect the limbic system and the aspect of the body's pattern as a union of several energy points. Applications of this study:Therefore, the authors conclude that this study is a new approach to seeing the process and expressing the significance of the zikrullah towards humans. The United Nations, especially WHO can use the results of this study to help humanity who needs a spiritual approach. Novelty:Zikrullah has been practiced for more than a thousand years.The name of Allah has been mentioned throughout the history of mankind, but an explanation of the aspects of zikrullah according to the scientific perspective has not yet been completed. The attention of Islamic scientists who are still little about the mystical phenomenon causes an explanation of aspects of zikrullah according to the scientific perspective has not been completed.

The sequence of the human brain can be configured by the originated strongly coupling fields to a pair of the ionic substances(bio-cells) within the microtubules. From which the dipole oscillation begins and transports by the strong trapped force, which is known as a tweezer. The tweezers are the trapped polaritons, which are the electrical charges with information. They will be collected on the brain surface and transport via the liquid core guide wave, which is the mixture of blood content and water. The oscillation frequency is called the Rabi frequency, is formed by the two-level atom system. Our aim will manipulate the Rabi oscillation by an on-chip device, where the quantum outputs may help to form the realistic human brain function for humanoid robotic applications.

Some buildings hold certain qualities of space design similar to those originated from nature in harmony with its surroundings. These buildings, mostly associated with religious beliefs and practices, allow for human comfort and a unique state of mind. This paper aims to verify such effect on the human brain. It concentrates on measuring brain waves when the user is located in several spots (coordinates) in some of these buildings. Several experiments are conducted on selected case studies to identify whether certain buildings affect the brain wave frequencies of their users or not. These are measured in terms of Brain Wave Frequency Charts through EEG Device. The changes identified on the brain were then translated into a brain diagram that reflects the spiritual experience all through the trip inside the selected buildings. This could then be used in architecture to enhance such unique quality.

Chapter 7 takes the investigation of the aesthetic impulse into the human brain to understand, first, why only we—and not our closest relatives among the primates—express ourselves aesthetically; and second, how the brain reacts when presented with aesthetic material. Brain scans are less useful when you are interested in the Why of aesthetic behavior rather than the How. Nevertheless, some brain studies have been ground-breaking, and neuroaesthetics offers a pivotal argument for the key function of the aesthetic impulse in human lives; it shows us that the brain’s reward circuit is activated when we are presented with aesthetic objects and stimuli. For why reward a perception or an activity that is evolutionarily useless and worthless in relation to human existence?

A 7-month-old, spayed female, domestic longhair cat with L-2-hydroxyglutaric aciduria (L-2-HGA) was investigated. The aim of this study was to investigate the clinical signs, metabolic changes and underlying genetic defect. The owner of the cat reported a 4-month history of multiple paroxysmal seizure-like episodes, characterized by running around the house, often in circles, with abnormal behavior, bumping into obstacles, salivating and often urinating. The episodes were followed by a period of disorientation and inappetence. Neurological examination revealed an absent bilateral menace response. Routine blood work revealed mild microcytic anemia but biochemistry, ammonia, lactate and pre- and post-prandial bile acids were unremarkable. MRI of the brain identified multifocal, bilaterally symmetrical and T2-weighted hyperintensities within the prosencephalon, mesencephalon and metencephalon, primarily affecting the grey matter. Urinary organic acids identified highly increased levels of L-2-hydroxyglutaric acid. The cat was treated with the anticonvulsants levetiracetam and phenobarbitone and has been seizure-free for 16 months. We sequenced the genome of the affected cat and compared the data to 48 control genomes. L2HGDH, coding for L-2-hydroxyglutarate dehydrogenase, was investigated as the top functional candidate gene. This search revealed a single private protein-changing variant in the affected cat. The identified homozygous variant, XM_023255678.1:c.1301A>G, is predicted to result in an amino acid change in the L2HGDH protein, XP_023111446.1:p.His434Arg. The available clinical and biochemical data together with current knowledge about L2HGDH variants and their functional impact in humans and dogs allow us to classify the p.His434Arg variant as a causative variant for the observed neurological signs in this cat.

Numerous studies have identified microbial sequences or epitopes in pathological and non-pathological human brain samples. It has not been resolved if these observations are artifactual, or truly represent population of the brain by microbes. Given the tempting speculation that resident microbes could play a role in the many neuropsychiatric and neurodegenerative diseases that currently lack clear etiologies, there is a strong motivation to determine the “ground truth” of microbial existence in living brains. Here I argue that the evidence for the presence of microbes in diseased brains is quite strong, but a compelling demonstration of resident microbes in the healthy human brain remains to be done. Dedicated animal models studies may be required to determine if there is indeed a “brain microbiome.”
