Each neurotransmitter will have a specific effect on specific nerve cells. Neurotransmitters can either be excitatory or they can be inhibitory. When a neurotransmitter is excitatory then they will be able to help communicate a nerve impulse. If a neurotransmitter is inhibitory then it will hinder the communication of the nerve impulse. A good example of a neurotransmitter that is excitatory is known as acetylcholine.
Self-Management Contract: Changing and Controlling Eating Habits Self-Management Contract: Changing and Controlling Eating Habits Maya Angelou stated, “If you don’t like something, change it. If you can’t change it, change your attitude” (Brainy Quotes, n.d.). Many people have behaviors they wish to change about themselves. Some of these behaviors may be to quit smoking, lose weight, change eating habits, become better parents, manage anger, manage time, begin exercising, control drinking, or even become a better student. With behavioral modification it is important to have a goal that is measurable, attainable, positive change, and something the person desires.
nor adrenaline and serotonin mainly. These neurotransmitters act like chemical messages in the nervous systems and are known to be active in parts of the brain associated with reward and punishment. They help to regulate the hypothalamus which is involved in sleep appetite , sexuality and physical movement., and these key areas are affected in depressive disorders. Support for this explanation has come from drug therapy. Anti depressants such as MAOI’s which increase the available amount of nor adrenaline in the brain, were found to be effective for elevating the symptoms of depression.
The fact that both twins wouldn’t always develop schizophrenia means that another factor must be involved, for example family environment. Too much or too little of a particular neurotransmitter may produce psychological disorders. For example, an increased level of dopamine is linked to schizophrenia, and drugs like cocaine, which increase dopamine levels, can lead to schizophrenia like problems. Also, depression can be effectively managed and often treated with drugs that manage serotonin levels in the brain. However, Watson et al found that low serotonin levels may in fact be due to environmental factors.
Bias in research- refers to beliefs that interfere with objectivity Placebo effect- a fake treatment, an inactive substance like sugar, distilled water, or saline solution can sometimes improve a patient’s condition simply because the person has the expectation that it will help them. Research Methods (*Study Chart, p.19) Case study-an in depth analysis of one person
c) How does one nerve cell communicate with another? - Nerve cells communicate with one another through neurotransmitters. 2. a) Explain what neurotransmitters are? - Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse.
Researchers suspect that the caudate nuclei form perform this selection function poorly with those with OCD. As suggested by the high level f frontal lobe activity revealed in PET scans, obsessional thinking then persists, often until a compulsive ritual puts an end to it. | One strength of the brain dysfunction theory comes from further empirical support provided by Comer (1998) who suggests that because serotonin plays a key role in the OFC and caudate nuclei, it is likely that low levels of serotonin cause these areas to function poorly. This suggests that there is wider academic credibility for a causal effect between serotonin and regions of the brain. A second strength of the brain dysfunction theory is that it has
Strengths of this study would include the large number of participants over various countries therefore a socio-cultural strength and more in depth data is produced. Another strength is the ability to access existing conditions or phenomena ethically. A weakness of this study would be using a self scale is unreliable as the participants might have a different approach on how intense the level of disgust is on the scale. Another weakness could be that there could be participants who have not taken the online survey seriously therefore altering the results. These results showed that because people find the pictures that harm our immune system more disgusting , we use the disgust gene as a protection against disease.
Not exercising can cause more serious issues then you think. Not only will you gain weight over time, but you have greater risk of diabetes, heart disease, and some types of cancer. For those who do exercise, they get the benefits that all could get. The benefits are the decreased blood pressure, live a longer life, have a better mood, less risk to obesity, heart disease, diabetes, and certain cancers. The reason why those who exercise live, because they are not getting fat over time as someone would be by just sitting at the couch all day.
It makes us more alert and energic therefore makes us more concentrated on the works we do, it boosts our metabolism so it helps us to burn more fat and prevents us from getting fat/obese. It also makes us smarter and with that it kind of protects us from getting Alzheimer’s and also it lowers the chance of getting Type II of Diabetes extremely. The second effect of caffeine is psychological. As caffeine has lots of nutrients and antioxidants it helps us to clear our thoughts and makes us more stress-free. It helps us to lift our mood but for some people it gives them anxiety on the contrary so while it is helpful for some people to get calm it makes other people to get more depressed.
