Based on the conducted research this work will explain what makes a serial killer kill on the example of a fictional character form a popular TV show Dexter Morgan. In order to understand the serial killer’s actions the paper will examine all of the ...

The advancements in modern medicine in the last few decades are responsible for new treatment methodologies in treating deadly diseases. However, there are some areas of the human body that still remain a mystery. The human brain is one of the more complex organs and there is no forseeable outcome irrespective of the infirmity. The medical community faces hard choices whenever they encounter a difficult situation involving brain damage. The chances for recovery from a severe brain damage are slim. Hence, during such times, a hospital staff will request the family for consent to withdraw specific medical treatment or ...

The principle of work of our brain and consciousness has always been a topic to investigate. This question is not only psychological, because it tries to get to know the deepest structures of our brain activity, but as well philosophical, as we question ourselves whereas we could believe in what we cannot see. Basically, I see it as it a discourse around the endlessness of our mind and its capacities. Are there any boundaries that cannot be crossed or it is an eternal structure that is unable to measure? Our mind is observed and considered by researchers in various ...

Summary

The neural network controls physical activities. Recently scientists have found out that the neural network can be observed to show different levels of activation depending on an organism’s mental activity. Scientists have gone further to devise actual methods that detect brain activity in particular instances. The brain and the neural network never stop working; however, certain tasks cause the brain and the neural network to work faster, harder and more intensely (Garcia). These unique activities usually register or appear as spikes or dips in the never-ending sequence of brain activity. Genetically Encoded Voltage Indicators (GEVIs) are a promising ...

Introduction

Maurice Merleau-Ponty begins his essay “Eye and Mind” with a comment on science. Studying the world in the manner that science does, takes a person out of one’s body, he says. It places the world in a series of definitions, constructs, indices and variables, allowing only the understanding of minute, exact changes to have a status of legitimacy. He says science “comes face to face with the real world only at rare intervals” (Ponty, 121). For any lover of art who lives in this practical, rational capitalistic society, this point of view is refreshing. Today, typically, the real world is referred to ...

Introduction

In the recent past, studies in the field of cognitive science have brought forth overwhelming evidence on the relationship between moral judgment and emotions. However, research on this topic a couple of decades old. For instance,StanleyMilgram, a social psychologist, carried a research on this topic in the 1970 where he instructed his students to approach strangers in New York subway and request for a sit. The research did not receive the kind of reception Milgram expected, he noticed that most of the students declined to participate. However, one student who offered to do the research aborted it prematurely. Left with no alternatives, ...

DREAMS

Dream is a natural physiologic process of being in a condition with the minimum level of brain activity and lowered reaction at the environment. It is a subsequence of images that can be remembered by a human. First experience of rational interpretation of dreams refers to III-I millennium BC applied by such Greek philosophers as Democritus, Plato, Aristotle, Artemidorus and others. But the initial attempt to create a systematic psychological theory of dreams belongs to an Austrian psychologist, psychiatrist and neurologist Sigmund Freud who described this theory in his book “The interpretation of dreams” (1999). He distinguished between the manifest and latent contents ...

Differences between Mind and Body

Our mind and body are the major constants in our lives. Philosophers and scientists have often raised questions on mind and body, the relation between the two. The starting point for any analysis would begin with a question - What is a mind and how does it differ from the body. Sure we all can view our bodies, but our mind remains hidden. Still, we can look at our brains but still not the mind as it is not capable of being inspected, in the same way, as a body is. A great deal of research has been done on the relation ...

Neurobiology of language comprehension in adults

Common studies used to understand association between neural networks and processing of non-literal language were from the study of brain lesioned patients. Brain imaging methods permit researchers and doctors to view problems or activities within the human brain, devoid of invasive neurosurgery. There are a couple of safe and accepted imaging methods in use today in hospitals and research all over the world. Techniques that measure brain activity can be grouped into either Functional imaging or electrophysiology. This paper aims to contrast and compare different brain imaging methods and behavioral studies done on patients with brain lesions to bring to a ...

The article, “Predicting Human Brain Activity Associated with the Meanings of Nouns” was written by Tom M. Mitchel, Svetlana V. Shinkareva and their five associates. The article was published in Science in May 2008. It outlined a computational program that predicted which parts of the brain were stimulated and would respond to certain words and images, or certain stimuli. I found several concepts of the article very interesting. For example, the basis of the article’s studies was founded on creating a computational framework subject to linguistics. In layman terms, a grid of the mind was drawn up, based on nouns. Scientists ...

Personal Development Aligned to the Course - In Comparing and Contrasting the

Introduction

The personal development gained from this course connects to my new tolerance of other peoples' unacceptable behavior, of forces creating limitations on my self-esteem, new insights to my understanding of my own and others' behavior, my new ability to view unwarranted claims expressed in the media or credentialed authorities, and finally, summarizing new awareness of psychology applied to everyday life. This understanding I continue assessing about behavioral psychology as the driving guide leading my effort in my personal development includes theories ...

It was originally thought that basal ganglia were responsible for voluntary motor movements, and movement disorders were associated with pathological changes in the basal ganglia. However, it was found that the basal ganglia are associated with different cortexes with distinctive circuits, which are called loops, so a pathological transformation of tissue can manifest as a psychological or motor disorder, depending on the loop affected. The cortico-basal ganglia-thalamocortical loop is a one-way circuit that allows the basal ganglia to receive input from the cortex and send output via the thalamus back to different regions of the cortex. Pathological changes in this loop are ...

Hypnosis

One’s perception of hypnosis often includes the idea of people charmed to do things while under a state of trance which can be either comedic or appalling in nature. This perception is often fueled by media titles with themes like sci-fi, fantasy, and even horror as these themes would show how hypnosis is done to remove one’s free will or bring one into a state wherein he finds himself in his own world while his body performs mechanically. While these media descriptions of hypnosis is somehow true given hypnosis’ definitions, many are left unaware as to the true nature ...

Scientists have for many years tried to determine exactly what causes dreaming, and the activities that occur in the brain during dreaming. However, the neurological, physiological and psychological functioning of the brain act in combination to determine what and how one will dream. Scientists believe that arousal and stimulation of the cortex and brain stem play a role in activating the central nervous system such that some impulses felt during the dream feel absolutely real. Some scientists believed that dreaming was initiated by rapid eye movement (REM) prior to sleeping. They proposed that dreaming depended on the stages of ...

Positron Emission Tomography (PET) is a method of medical imaging that works by detecting gamma rays produced by the interaction of electrons with positrons after a tracer radionuclide is injected into the body. The tracer radionucleotide used is dependent on the part of the body that is being investigated, in some cases it is modified glucose, in others, it is a receptor ligand. Common uses of PET scans are cardiac studies that measure the oxygenation of the tissues of the heart and the function of the heart muscle, to detect skeletal trauma and bone cancers, kidney imaging to study the renal function ...

Fetal Alcohol Syndrome is a collective name given to physical and mental birth defects that are as a result of alcohol intake during pregnancy (Pytkowicz 32). Pregnancy is taken as an immensely precarious time for both the mother and the child. Although not harmful when taken in reasonable amounts, alcohol consumption is not advised during pregnancy. This depressant is taken for various beneficial reasons including relaxation and more importantly digestion. Nonetheless, alcohol has very damaging effects if abused, and these effects are exacerbated during pregnancy. The main cause of Fetal alcohol syndrome is alcohol consumption. Apparently, alcohol travels to the ...

The differences between men and women have plagued philosophers and the common man for millennia; is there really any true difference that stems from biology, or is the male tendency to fight and the female tendency for emotionality a product of our upbringing, as well as social expectations? In my perspective, there are quite a few significant differences that exist between men and women, but they do not have to be the case; there are always exceptions to the rule, but many societal and behavioral (not to mention physical) truisms exist that lead to the tendency for men and women to ...

Mind and Body Connection in Learning

Wolfe, (2010), defines learning as the process of developing new knowledge or performing new behaviours. The process not only takes place in a classroom but throughout an individual’s life time. Therefore the process is of essence in humans and it is especially used by professionals such as politicians, advertisers, and employers to influence consumers, voters, and workers. Learning process is very close to memory—storage of information in the brain—and therefore the process shows positive signs of mental and intellectual development. It is for this reason that this paper will show the link between mind and body in ...

Growth in technology has ensured that people from all over the world can interact in real-time. Human beings are social creatures, thus, it is their nature to include fun in their interaction. Advanced technology has over the years ensured that games are an integral part of human interaction all over the world (Jansz et al. 269). This interaction of people as a result of sharing and participation in various games on the internet is known as online gaming. Online games like Warcraft amongst others provide a getaway to people getting into a fictional and fantasy world from the normal, regular and real ...

Introduction
