Serotonin is a 'transmitter' chemical - it helps to pass nerve impulses from one nerve cell (neurone) to the next over the synapse (gap between two neurones).
It works like this;
1. When a nerve impulse travels the length of a neurone and reaches the end it must 'jump' the gap between one neurone and the next.
2. To do this, the impulse triggers the release of a transmitter chemical (such as serotonin) from the end of the neurone into the synapse.
3. These transmitter chemical molecules diffuse across the gap between the two neurones, and bind to special receptor molecules on the membrane (outer skin) of the next neurone.
4. When these transmitter chemicals bind to the right receptor molecules they trigger a new impulse carrying the same 'information' as the impulse in the previous neurone.
Serotonin is simply one of the many 'transmitter' chemicals.
Serotonin can also do the following:
1. It gives us self-confidence, a feeling of safety and security.
2. It causes us to feel sleepy.
3. It increases our appetites.
The part of the brain where it does each of these 3 things is a different part of the brain from the part where the other 2 things occur. Thus, for example, increasing serotonin in the part of the brain where self-confidence is will increase your self-confidence, but not your sleepiness. Unfortunately, we have no medications to increase only the serotonin in one part of the brain. This explains why medications to increase serotonin in the brain can also cause increased appetite and sleepiness.
Medications which increase serotonin in the brain (SSRI's such as citalopram, escitalopram, fluoxetine, paroxetine, and sertraline and SNRI's such as venlafaxine and duloxetine) give us more self-confidence, and a feeling of safety and security.
By the way, serotonin also exists in our gastrointestinal tracts. In this location, it stimulates digestion. This is why such medications can cause gastrointestinal upset. But they can also help constipation.
Are serotonin receptors the only binding sites for LSD?
No, LSD binds to other receptor sites besides those for serotonin, including dopamine and adrenergic receptors. Compared to compounds such as psilocybin, it is less selective for the 5-HT2A receptor.
How is the skull exposed before the extraction of the brain?
During an autopsy, the skin covering the head is pulled down frontally exposing the bone. A section of bone is removed allowing access to the brain for examination, part of which requires extraction.
Can you get brain damage from high levels of co2?
The brain and lungs continually use an O2-CO2 feedback mechanism. High CO2 in the body triggers us to breathe. High CO2 in the air, however, eventually cause us to stop breathing after period of deceased oxygen. This causes brain damage and can cause organ damage.
Is important for anger.
What does the cerebral cortex cover?
The cerebral cortex is the outer layer of the cerebrum, or large brain. It also is where most of the grey matter, i.e. neuronal cell bodies, are found. So you could say that the cerebral cortex covers the white matter of the cerebrum.
What is the blood supply to broca's area?
The left middle cerebral artery supplies blood to broca's area.
What part of the brain is the motor command center?
The brain is the centre of the human nervous system and it sends out most of the commands (some outomatic decision do not require the brain such a flinching when you touch something really hot). Commands are sent down the nerve in the spinal column
Does Reliv treat brain injury?
One perspective:
Nothing will treat adult brain injuries. An adult brain cannot regenerate its own cells. Adult brain injuries are virtually always permanent, and they are also often permanent with children (depending on age). Any company that claims to be able to treat brain injuries with its products is very questionable.
Another perspective:
There are many complaints to be found on the internet about both their company and their products. Hundreds of websites talk about their illegal code of practice, and their bad treatment of employees. Others talk about hidden ingredients in their products. You will have to do some of your own research and come to a decision, but I personally advice you to simply juice your own fruits and vegetables. That method ensures that you know that the product will not hurt you, will help you, and you don't fund an evil corporation. There are enough of those in this world as it is.
Another perspective:
The science behind Reliv products come out of an original 10 year study by a gentleman named Dr. Ted Kalogris on the regeneration of human cell structure - the perfect balance of nutrients to cause healthy human cells to regenerate.
There ARE a number of people who have taken and are taking Reliv products whose doctors have documented results with brain injuries after taking Reliv.
A different perspective
Being granted a patent is no assurance of the efficacy or safety of any drug because there are no tests carried out. Anecdotal evidence like that given here must not be relied on: the only way to measure the efficacy and safety of a drug is to do proper, controlled clinical trials. I doubt if any have been done on Reliv and it should therefore be avoided at all costs, particularly for serious medical conditions.
Regarding Clinical Trials
Reliv has had clinical trials conducted by doctors, scientists and other industry professionals.
What is location of cerebellum?
The cerebellum is found in the back lower part of your brain. This is literally the main controller of your brain.
Is a subdural hemorrhage a terminal disease?
A subdural hematoma (hemorrhage) is usually the result of a serious head injury. When it occurs this way it's called an "acute" subdural hematoma. Acute subdural hematomas are among the deadliest of all head injuries. The blood fills the brain area very rapidly and compresses the brain tissue. This often results in brain tissue injury or infarction and many times even death. In the elderly, subdural hematomas can also be a result of a slight knock to the head or falls.
Why do boys date different girls?
boys date different girls because they either like different girls every week or they want to play the field.......but mostly because they like different girls every week.
How many percent can Buddha use of his brain?
Probably 100 percent, because if you become a Buddha you achieved maximum level of consciousness
Which brain imaging method uses magnetic properties of different atoms to take sharp, three-dimensional images of the brain.
What part of the brain causes what specific types of behavior?
Different parts of the brain are responsible for various types of behavior. The prefrontal cortex is involved in decision-making, impulse control, and social behavior. The amygdala plays a key role in processing emotions, particularly fear and aggression. The hippocampus is crucial for memory formation and spatial navigation, influencing learning and behavior related to past experiences.
Which unit of the brain is responsible for the sense of balance?
Balance and hearing both derive from the same organ, the cochlea, therefore the auditory center of the brain is also responsible for perceiving balance.
