This means food, sex, and several drugs of abuse are also stimulants of dopamine release in the brain, particularly in the prefrontal cortex. Because the BAS is associated with dopamine, it is easy to understand why the BAS is sensitive to reward cues. “The BAS activates behavior in response to cues of reward or non-punishment” (O’Brien, Frick 1). The BAS motivates us the find pleasure. In contrast, the BIS is associated with the neurotransmitter Serotonin and brain structures that control memory.
The notion of sense perception as a WOK uses touch, sight, taste or hearing to gain understanding or knowledge on a particular subject. It is the way we interpret the environments around us. This way of providing meaning is different from person to person and is hard to investigate. This links to scientific realism, with the idea that the way one may see the world can differ to the evidence provided by science. This is often possible with a patient suffering from anorexia as they continue to loose weight to feel better, even though doctors and experts are telling them that this desire and action is the main reason they
Words and languages spoken affect human perception of things. Words are weapons mightier than swords that can change the entire human psyche. In a world where humans co-exist surrounded by social activity, language becomes one of our main mediums of expression. Emoto’s water experiment observed the power of words, as water stamped with positive words created far more aesthetically pleasing crystalline molecular structures, than did the water stamped with negative phrases. (High Existence) Humans form mental models of the world using a system of beliefs, which also include their underlying assumptions.
Emotions can sometimes get in the way of our utilitarian decision-making as evidenced by Anderson’s (2003) rational-emotional model. Plato and Descartes regarded emotion as the “enemy” of reason and rationality. However, Aristole and Spinoza posited that emotions such as fear, love, and sadness can also play a functional role in our lives. With self-help books like The Happiness Project by Gretchen Rubin topping best-seller lists and increasingly sophisticated therapies for emotional maladies being prescribed for daily use such as Prozac and Xanax, society is demanding more answers about how the mind controls our emotions. Branches of psychology such as positive psychology, pioneered by Martin Seligman of the University of Pennsylvania, have
Despite the author believing that procrastination can be beneficial and mentioning some strong and valid ideas, He doesn’t provide good arguments and there were logical fallacies and weak evidence. It’s in our human trait to delay tasks that will make us mentally think or physically work. We procrastinate because it’s in our biological nature. There is a scientific reason behind procrastination, Part of the brain structure, the limbic system, contains the center responsible for pleasure while another portion of the brain, the prefrontal cortex, is responsible for planning and making decisions. The limbic system dominates the prefrontal cortex at often
They also believe that the two factors that can lead to depresion are the neurologic argument and the genetic argument. We know that the brain functions by sending chemical messages from neurons to neurons using neurotransmitters such as Serotonin ( which release a chemical that helps a person to be calm) and Noradrenaline ( body's initial stress response) . The lack of this chemical messages, according to biological approach, is one of the reasons that lead a person to depression. The cure for the depression, according to the biological approach, is the use of chemical medicines such as Prozac (works by increasing the availability of the mood chemical serotonin) and Effexor (targets serotonin and
The same mind-body power that can heal you, can also harm you; this is where the Nocebo effect takes place. The basis behind these two events is called the “meaning response” and it alludes to the brain’s power to lead to effects in reaction to whatever it considers the truth or, positive or negative. If the substance is seen as beneficial it can heal, but if it’s considered as damaging, it is more likely to produce negative effects. For example, when patients in double-blinded clinical tests are warned about the side effects they may encounter if they’re given the real drug, approximately 25% experience sometimes severe reactions, even when they’re only taking a placebo, such as sugar pills. Some of these symptoms include weakness, puking, lack of muscular strength, colds, ringing in the ears, confusion with their taste recognition, memory loss or disorder, and other symptoms that should not result from these fake medications.
It is in fact very interesting the bodily changes that take place in an event that triggers fear. In the book How to Live Without Fear it talks about how even though fear is a natural human emotion there are way to try to get rid of it. Fear is an emotion that takes so much energy and in this book by Dr. K Sri Dhammananda tells us that we can learn to handle fear and instead of feeling unhappy use this energy to distract our minds. We often feel the emotion of fear because we are to focused in it if the human brain stops worrying and distracts the mind we can overcome
Volatile anesthetics can alter the dopaminergic balance in the brain, but whether they exacerbate PD is unknown. Propofol produces both dyskinesias and ablation of resting tremor, suggesting that it has both excitatory and inhibitory effects in this patient population. But both volatile agents as well as propofol has been successfully to sedate patients with PD during deep brain stimulation surgery. Dexmeditomidine appears to be safe and when used in deep brain stimulation surgery has advantage of not interfering with motor symptoms. Ketamine should be used with caution because of potential interaction between levodopa and ketamine’s sympathomimetic activity.
This is true if you try to change someone else's behavior without first trying to change your own. It has been my experience that you can, in fact, alter others' ways of acting by altering your own first, just as Gandhi noted. William James, pragmatist philosopher & psychologist (1842 - 1910) said, "the greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind." I would go further and say that human beings can alter other people's lives by altering their own personal attitudes of mind, as I've described above. When you change your attitude of mind, that is, the way you habitually think (an attitude is nothing more than a habit of thought), then you alter the way you behave and this, in turn, alters the ways others behave toward
The blood brain barrier’s main goal is to protect the brain from toxic agents. By doing this, it can interrupt or block the delivery of therapeutic drugs to our brain. Many trials have been attempted to try and force the transport of drugs across the BBB, but some of these ways can structurally damage the BBB. The ideal goal would be to find a way to control the transport drugs across the barrier, but not damaging it at the same time. The most ideal approach found for this goal was “nanobiotechnology-based” delivery.
Trauma can range from, automobile accidents to physical harm. Although EMDR does not remove the problem which may have caused the sense of discomfort and insecurity. It does provide ways to change how the patient perceives the incident now, in the present. In Dr. Shapiro’s book, Getting Past Your Past: Take Control of Your Life with Self-Help Techniques, she provides, “numerous procedures that will allow the reader to identify the earlier memories that are at the root of their problems, and ways to change their emotions, physical sensations and negative thoughts” (Shapiro). The goal of EMDR is to, “achieve a complete state of emotional health”
“One of the health risks involved with the use of steroids is the effect they have on the brain. Unlike some abusive drugs, steroids do not cause immediate effects on the neurotransmitter dopamine, which is responsible for the “high” one gets while using drugs for recreation. Long-term use of steroids, however, can result in disrupting some brain pathways and chemicals including dopamine and opioid systems. If this occurs then steroid users can develop aggression, which is where the term “roid-rage” comes from, along with other psychiatric problems, which scientists term as a “psychosomatic state” (Fahey, 1998). The heart is an area of major concern for steroid abusers.
