Recommended: How. Neurotransmitters impact on human behaviour

One of the principles of the biological level of analysis is that behavior is a result of various complex processes. Human behavior is likely to change due to self-related, environmental, and social influences. Nuerons in our body can often be called the building blocks to behavior. Therefore, neurotransmission, the method in which the neurons send messages that creates a synapse, essentially creates the behavior. Different neurotransmitters hold different effects to human behavior like serotonin with the effect of arousal/sleep and dopamine with the effect of pleasure. This exhibits how neurotransmission has an effect on human behavior.
Serotonin, the neurotransmitter responsible for arousal, when released may impact your thinking and reasoning skills. Low levels of serotonin are linked with antisocial and impulsive behavior; serotonin also regulates sleep, arousal levels and emotion. The feelings you experience may handicap one’s normal everyday behavior. One study involving serotonin is a Japanese monk study (Kamatsu and Hirai {1999}). The researchers studied how sensory deprivat...

    Briefly explain the process of neurotransmission. Neurotransmission starts with the neuron, the most important part of the central nervous system. A neuron contains a cell body, axon, and dendrites. When a neuron receives an electrical impulse, the impulse travels away from the cell body down the axon. The axon breaks off into axon terminals. At the axon terminals, the electrical impulse creates a neurotransmitter. The neurotransmitter is released into the synapse, a space between two neurons. If the neurotransmitter tries to stimulate a response of another neuron, it is an excitatory neurotransmitter. If the neurotransmitter does not stimulate a response of another neuron it is an inhibitory neurotransmitter. If a response is generated, the second neuron or postsynaptic neuron will receive an action potential at the site of the dendrite and the communication process will continue on. If a response is not generated, neurotransmitters left in the synapse will be absorbed by the first neuron or presynaptic neuron, a process known as reuptake. Neurotransmitters control our body functions, emotions, and

    In order to increase the level of serotonin, you should eat Tryptophan rich foods like tuna, salmon, dairy products, nuts and etc. At second step, you should get outside of the sunlight and absorb Vitamin D. Sun is considered to be best source for Vitamin D. Serotonin production is mainly based on availability of vitamin. It is a component of protein and which human will eat normal diet consume in significant amounts. One will increased with his weight by eating more carbohydrates. This serotonin will be helpful to promote happiness, relaxation and sleep. It is sometimes known as happy neurotransmitter. If there are any deficiencies in molecule, it will lead to depression. Individuals who are feeling difficult to sleep cannot try glass of warm milk before bed. There is some speculation that the popular thanks giving day coma where people will feel tired after a big meal. It is a kind of hormone which helps people to feel relaxed and contented. Similar to many hormones and brain chemicals, serotonin is having role in optimizing the concentrations. It is formed by the acid named tryptophan. It will work to make one to feel sleepy. Serotonin inside our body helps in increasing the ability of being relaxed, happy, confident and calm. It can regulate the memory and temperature. Apart from internal health, it will also help in the external health like with skin. It can be said as boon to the skin. Another name feel

  • Depression and Antidepressants

    2869 Words  | 6 Pages

    I am quite fascinated by generalized control mechanisms and the role they play in the nervous system. I am also quite curious about the relationship between different generalized control mechanisms. The concept of mood and depression in particular have always interested me. I have always wondered what actually causes depression. Why can some people be in a perfectly good mood one day and then less than a week later start exhibiting the signs of clinical depression? I have always been curious about the role that experience and chemical imbalances play in depression and other mood disorders. I donUt totally understand how chemical depression can originate as the result of severe outside stressors in a personUs life. How can this stress go from simply stress in the experiences and environment of a person to a chemical imbalance? I have also wondered why certain people are more susceptible to depression than others. I am curious about whether genetics play a role in depression and whether certain people are more susceptible to depression because of the environment they live in or because of pharmacological reasons and genes. Throughout our class this year, I have wondered about the role that the I-function plays in depression. I find it interesting that it is possible to wake up one morning and be in a nasty mood even if I want to be in a good mood and my I-function is thinking RhappyS thoughts. Through my research for this paper I wanted to find out more about the different kinds of depression and exactly what goes on chemically in the brain when a person is depressed. I also wanted to do a little research on how depression can be treated. I wanted to try and determine how and when the line of simp...

    Depression is a mental illness, which affects millions of Americans each year. Currently there are many prescription drugs, called anti-depressants that have been proven to successfully treat it. The causes of depression are somewhat of a medical enigma, however, it is known that depression is associated with a change in the brains chemistry involving the function of neurotransmitters (Reichert). This chemical change occurs in healthy brain’s, which experience sadness, but ends after the unpleasant stimulus is removed. In people suffering from depression this chemical change does not correspond to any particular stimulus. Symptoms of depression are often incapacitating and include severe and extended sadness, feelings of worthlessness, feelings of emptiness, irritability and anxiety (Reichert, Spake).

    Behavior is the result of stimulus-response even if it was so complex that it couldn’t be explained. Watson description of the stimulus response was “ To predict, given the stimulus, what reaction will take place; or, given the reaction, state what the situation or stimulus is that has caused the reaction” (1930, p. 11). Throughout time and history, the idea of behaviorism has not changed all that much. (McLeod S. A.)

  • Serotonin & Depression

    1170 Words  | 3 Pages

    In the brainstem, the most primitive part of the brain, lie clusters of serotonin neurons. The nerve fiber terminals of the serotonergic neurons extend all throughout the central nervous system from the cerebral cortex to the spinal cord. This neurotransmitter is responsible for controlling fundamental physiological aspects of the body. In the central nervous system (CNS), serotonin has widespread and often profound implications, including a role in sleep, appetite, memory, learning, temperature regulation, mood, sexual behavior, cardiovascular function, muscle contraction, and endocrine regulation. Not only does this bioamine control physiological aspects of the body, but it also has an involvement in behaviors like eating, sleeping and aggression. Serotonin has been noted to produce an inhibitory effect on the nervous system that calms, soothes and generates feelings of general contentment and satiation.

    On the other hand, one of the strengths of the behavioural approach over the psychodynamic approach, is in the terms of testability, since it only focuses on behaviour that can be tested and observed, which makes it very useful in experiments under a laboratory setting where behaviour can be repeatedly observed and verified. Therefore, the results derived from behavioural approach have been, and continue to be, objectively and reliably

    The behavior theory or behaviorism is very useful in the medical career field. Both nurses and doctors can benefit from this theory of learning. Behaviorism is mostly concerned with observable behavior. One of the criticisms of this state that it does not focus on the internal factors of the brain. In an addiction the brain is provided pleasure be releasing dopamine. “Addictive drugs provide a shortcut to the brain’s reward system by flooding the nucleus accumbens with dopamine. The hippocampus lays down memories of this rapid sense of satisfaction, and the amygdala creates a conditioned response to certain stimuli.” (1) The behavior theory of psychology was first discovered in the 1890’s by Ivan Pavlov a noted Russian physiologist.

    "The premise behind the biological perspective in psychology is that all actions, feelings, and thoughts are associated with bodily events." Biological psychologists examine how all of the electrical impulses, hormones, and chemicals flowing through the body can effect behavior and how changes to these bodily functions can change behavior. They are concerned with how the aspects of biology effect peoples' emotions, learning abilities, and their perception of events.

    Looking at the eight behavioral subsystems closer Ingestive subsystem fulfills the need to supply the biological requirements for food and fluids. Eliminative subsystem functions to excrete waste. Affiliative subsystem also known as attachment subsystem serves the need for security through social inclusion or intimacy. Dependency subsystem is those behaviors designed to get attention, recognition and physical assistance. Sexual subsystem serves the biologic requirements of procreation and reproduction. Aggressive subsystem functions in self and social protection and preservation. Achievement subsystem functions to master and control one's self of the environment (Gonzalo, 2011). The eighth subsystem is restorative these are behaviors that are associated with restoring of energy and equilibrium. These include behaviors like sleep, fatigue, recovery, leisure and recreational interests (Andrews, Cromwell, Fries & Hodge, 2008).

    Neurotransmitters are chemicals in the brain and body that help transmit electric signals from one neuron to other neurons in the body. These neurotransmitters are responsible for the activation of behavioral patterns and tendencies in specific areas of the brain. When a neuron releases the neurotransmitter chemicals, healthy synapse are needed to pass the electric message across the gaps correctly. All of this is important in an individual’s criminal behavior because the transportation of neurotransmitters like dopamine and serotine control a person’s emotions and therefore their behavior. “Dopamine is a neurotransmitter in the brain that is associated with pleasure and is also one of the neurotransmitters that is chiefly associated with aggression.” (Jones, C. M.). An individual usually experiences high levels of dopamine before and after an altercation and it can cause an individual not to recognize the lasting angry expression they have on their face. Also, “Serotonin is a neurotransmitter that is key in information processing and most consistently linked to criminal behavior in its deficiency; low levels are linked to depression and other mental illnesses” (Schram, P. J., & Tibbetts). People with low levels of serotonin have trouble communicating in everyday life and this has a strong connection with criminality because people that
