I found in the video watched in class, Why Leaders Eat Last by Simon Sinek to be informational and explanatory. I also, found towards the end of the video when talking about cortisol to be worrisome compared to the other neurotransmitters. Endorphins masks physical pain, at the gym I notice that while I feel good doing stairs and after later on I feel the pain. Dopamine makes us feel good, I have noticed that when I get through my goals for the day of homework and test I get and feel that jolt of dopamine so I want to get through my goals for the next day. Serotonin this week right after watching this video I went outside it was sunny and I put on my designer sunglasses and realized that I will wear expensive shoes, clothes, and glasses just

Exercise and the act of any bodily motion requires chemistry to power all of the necessary moving parts. There are two functions of exercise that make you feel good while working out and then make you feel not so good. The first “feel good” process is the releasing of endorphins during a workout. Endorphins are chemicals released by the pituitary gland of the brain. The pituitary gland produces approximately 20 different types of endorphins that assist the human body with a variety of functions. Endorphins diminish the brain’s ability to perceive pain, which is similar to the function of sedatives. A few examples of the benefits of endorphins are that they help with stress reduction, relieving pain, boosting immunity, slowing the aging process,
In the classic poem and plays Julius Caesar by William Shakespeare, Oedipus the King by Sophocles, and The Odyssey by Homer, the main characters are leaders with differing successes. Julius Caesar gets killed by his own "friends", Oedipus gouges out his eyes, and Odysseus faced many setbacks, but managed to get home. All of these classical heroes had one thing in common. This was that they tried to lead by dominance. In Julius Caesar by William Shakespeare, Oedipus the King by Sophocles, and The Odyssey by Homer, all of
The most obvious aspects to address with runner's high are the biological and psychological aspects that can be associated with it. When the body is put under stress the mind reacts accordingly. This is why endorphins are commonly associated with runner's high. Endorphins are any of a group of opiate proteins with pain-relieving properties that are found naturally in the brain. The word "endorphine" comes from endogenous, meaning "produced within the body" and morphine, a chemical substance derived from opium that elevates mood and reduces pain. Endorphines in turn are neurotransmitters that are chemically similar to morphine.1 It has been realized that the brain responds to morphine and that morphine receptors are in the brain.
Why is it that something as seemingly innocent as love and support can prolong life or improve someone's health? Is there any neurological evidence that positive thinking, love, and help can actually stimulate the brain to improve health? And how about the placebo effect? How is it that people can get better subconsciously? It seems that some health improvement can either happen consciously (I-function) as in the case of emotional support, or subconsciously (without the I-function) as in a placebo effect.
The problem is, is there a biochemical explanation for this "runner's high," or is it a purely psychological event (although one can also say psychology is biochemical)? Exercise addiction, similar to substance addiction, seems to suggest that jogger's euphoria could be biochemical. There have been accounts of runners who experience withdrawal symptoms when not exercising - such as edginess, anxiety, and other unpleasant feelings. Research shows that the body produces its own opiate-like peptides, called endorphins, and like morphine, they can cause dependence (Farrell et al. 1982). Thus, this is just one hint suggesting that these "endogenous morphine" compounds may be the chemicals causing all these psychological effects of exercise. In general, endorphins are known to be responsible for pain and pleasure responses in the central nervous system.
produce euphoria in addition to pain relief. Many of the problems related to opioids stem from
Animal and human research studies illustrate the contribution of the central opioid systems in Major Depressive Disorder (MDD). The most common endogenous opioid has been found to be beta-endorphin (Hegadoren, 2009). Low levels of plasma beta-endorphin lead to depressive symptoms. Many individuals with MDD do not respond completely to traditional anti-depressant medications. Effective alternatives to medications, including exercise, electroconvulsive therapy, and acupuncture, help to alleviate depressive symptoms through increasing plasma beta-endorphin levels.
Drugs seem to cause surges in dopamine neurotransmitters and other pleasure brain messengers. However, the brain quickly adapts and these circuits desensitize, which allows for withdrawal symptoms to occur (3). Drug addiction works on some of the same neurobiological mechanisms that aid in learning and memories (3). "This new view of dopamine as an aid to learning rather than a pleasure mediator may help explain why many addictive drugs, which unleash massive surges of the neurotransmitter in the brain, can drive continued use without producing pleasure-as when cocaine addicts continue to take hits long after the euphoric effects of the drug have worn off or when smokers smoke after cigarettes become distasteful."

The Civil Rights Movement in the United States took place mostly during the 1960s. This movement had many strong faces ready to lead a movement of African-Americans to get the rights that they deserved. However, it was two of the less-recognizable faces that helped shape the movement. Ella Baker, who wanted to put a change in the system, and Fannie Lou Hamer, who is well known for her actions on trying to gather support, were two women who helped change the way the Civil Rights Movement played out. The SNCC, Student Nonviolent Coordinating Committee, was formed to prevent violence from younger blacks, and to try and settle the issue of segregation in a peaceful manner. Fannie Lou Hamer and Ella Baker both had ideas on how to change the unacknowledged racist policies of some states at the time, and their way to leadership roles within the African-American society is intriguing for both women.
In “Happiness and Its Discontents” Daniel M.Haybron describes the relationship between pain and happiness. Put simply, pain doesn 't bring happiness,happiness comes from within.

The study presented in this presentation focus on four different aspects of the influence of neurotransmitters that have an influence on eating. The first aspect is a 36 amino acid peptide transmitter known as the NPY. The NPY contains five different receptors; Y1, Y2, Y4, Y5, and Y6. Y2 is specifically geared towards memory. Y5 pertains to eating. Y6 is found in some animals, but not really found in humans. The Y1 and Y5 receptors are specifically for eating. The more NPY found within the body, the more a person would eat. A question, which was presented in this presentation, was if certain areas of the brain could be identified as being responsive to the metabolic action of the NPY. In order to study this idea, and experiment was performed where NPY was injected directly into different target areas. From this, it was shown that there were specific areas of the brain that responded to the levels of NPY differently.
I want you to imagine for a minute that you are in physical or mental pain, you are struggling very bad with your school work, or that you are going through something in your personal life that is taking its toll on you.
These are emotions that help us to be social. They include compassion, joy, love, loneliness, and euphoria. Scientists have been acting narrowly thus focusing on negative pro-social emotions. Of late, this perspective has been broadened to have the scientists think upright and be constructive. There are emotions such as altruism, gratitude, and forgiveness increases the mental health and well being of people and those who surround them. One can understand the aspects that lead to pro-social emotions. Such emotions start from the group and later affect an individual. The pro-social emotions can help improve the well being of an individual plus their mental health. Mental health involves psychological well being. This means, there is no spiritual illness (Colins, Oliver, & Henrik, 198). Broadly, psychological health is the mental state of a person functioning at an emotional level that is satisfactory. An individual would enjoy life under holism, or the constructive mental health. Prosocial emotions, therefore, contribute to the good health of people's
