Serotonin: A Classic Neurotransmitter Linked with Many Disorders Serotonin has a range of influences on the neurological and physiological function of the body. It has a significant influence on sensitivity to pain‚ emotionality‚ and a behavioral response to positive and negative consequences. Serotonin‚ along with other major neurotransmitters‚ is also linked with psychotic disorders such as schizophrenia. Serotonin‚ or HT-5‚ also has an effect on sleep‚ eating patterns‚ and thermoregulation

depression. From the scientific view point‚ the only way to treat depression is with medication. But in recent studies‚ the serotonin hypothesis says differently. The medication does not treat the disorder but only the symptoms. The serotonin hypothesis dates back to the 1960s. Depression is associated with a reduction in serotonin uptake sites and an increase in some classes of serotonin receptors. It’s a major depressive disorder. Used to be thought of an illness of the soul but currently as a disorder

Biological level of analysis – serotonin Serotonin is a neurotransmitter which plays different roles in our brain‚ and can have effects such as sleep‚ arousal levels and emotion. The study was conducted by two researchers‚ Kasamatsu and Hirai‚ at Tokyo’s University in 1999. The aim of the study was to find out how the sensory deprivation affects the brain and later on‚ the human behavior. In order to achieve their aim‚ the researchers examined a group of Buddhist monks who went to a religious

Before‚ during and after pregnancy moms may have or may experience depression. I have decided to do my research focusing on SSRIs (Selective Serotonin Reuptake Inhibitors) used to improve depression. My preference is to take a holistic approach‚ using natural remedies first and if necessary moving to pharmaceutical drugs. SSRIs are used to help improve depression symptoms and other disorders such as anxiety. Some common drug names of SSRI’s are Citalopram (Celexa)‚ Escitalopram (Lexapro)

forms like Serotonin‚ Dopamine‚ and Norepinephrine. All three of these neurotransmitters play a very important role in maintaining normal mood‚ motivation and concentration. What is Serotonin? Serotonin acts as a neurotransmitter‚ a type of chemical that helps relay signals from one area of the brain to another. (Bouchez‚ 2007) In depressed brains‚ the Serotonin signal had been somehow weakened because of a chemical imbalance in the neurotransmitters. (Mukherjee‚ 2012) Low Serotonin levels are

well-being. Many research applications have looked at the profound role serotonin plays in regulating mood and the affect exercise has on the body’s ability to produce increased amounts of serotonin. Other research has looked at levels of phenylethylamine before and after exercise and has concluded that increased levels result in what many have termed the "runners high". This researcher believes that it is a combination of both serotonin and phenyethylamine that contribute to feelings of well being after

to suggest that the neurotransmitters serotonin and dopamine are linked to aggression‚ low levels of serotonin and high levels of dopamine. Serotonin is a hormone that makes you happy; it helps to reduce aggression and inhibits responses to emotional stimuli that could potentially lead to aggression. Low levels of aggression are associated with increased susceptibility to impulsive behavior‚ aggression and violent suicide. Some drugs can alter the serotonin levels in our bodies and cause increased

in the levels of serotonin and dopamines are characteristic of anorexia. Bailer et al compared serotonin activity in women recovering from restricting anorexia with those recovering from purging type anorexia with a healthy control group. They found that the group recovering from purging type anorexia had higher serotonin activity. They also found the highest levels of serotonin in women who showed the most anxiety. They concluded that this suggests that the disruption of serotonin levels might result

Aggression in humans has been associated with low levels of serotonin and high levels of dopamine. Usually‚ serotonin has a calming effect‚ which inhibits aggression. When serotonin levels are low‚ this inhibitory effect is removed and people are less able to control their aggressive behaviour. Evidence for the importance of serotonin comes from two main sources. Brown (1982) found that there were low levels of the waste products of serotonin in the cerebrospinal fluid of individuals who are prone

research studies conducted over the past three decades suggest that central neurotransmitters play a key role in the modulation of aggression in all mammalian species including humans. Specific neurotransmitters systems involved in aggression include serotonin‚ dopamine‚ norepinephrine‚ GABA‚ and neuropeptides such as vasopressin and oxytocin. Neurotransmitters not only help to execute basic behavioral components but also serve to modulate these preexisting behavioral states by amplifying or reducing
