What is the function of the neurotransmitter orexin in the brain?

Orexin has a key function in human neurology and physiology. It is a regulator in and around the hypothalamus which affects one's hunger, fatigue and general arousal. Though its quantity in our anatomy is far less than that of of other neurotransmitters, its role is no less important.

Where is the thermostat of the body located?

your body is like a thermostat because you sweat to cool of and shiver to get warm. With a thermostat if it's cold the thermostat warms your house. When it's warm outside the thermostat cools your house. Thats why your body and a thermostat is a like.

Which structure helps relay information from higher brain regions to the cerebellum?

Most often, it is the thalamus that is the relay station to the cerebrum, although all of the structures have interconnections.

How long does it take the human body to start producing normal serotonin levels?

The time it takes for the human body to start producing normal serotonin levels can vary widely depending on factors such as individual health, diet, lifestyle, and whether any treatments or medications are involved. Generally, if a person begins making dietary or lifestyle changes, such as improving their nutrition or increasing physical activity, they might start to notice improvements in serotonin levels within a few weeks. However, for those undergoing treatment for serotonin-related issues, such as depression, it may take several weeks to months for medication to effectively balance serotonin levels.

Can Brain-Damage ever be fixed?

Brain damage is serious injury, It takes alot to fix it, it could cause memory loss, memory loss is caused in the brain area to run into something, hitting the brain area where memory is kept inside can be lost easily, by jerking it can cause damage, too much can cause you not to remember what happened, because of so much pain in the area. Doctors who are professional can fix it, they sure can! They can't fix memory loss, unless teaching the patient everything they don't remember. The two most important parts of the body are the brain and the neck. Well, we need lungs too. Patients might have to remember things on they're own. Serious brain damage can cause death if not fixed on time. Bruising your head or getting a tiny scratch on it doesn't matter, it will heal. But cutting it open or bruising the brain is an emergency, doctors can't fix that, only surgens. Profesional surgens. Over 1,000 people have died from getting damaged brains, broken skulls and anything having to do with the brain.It's very important to keep the brain safe. Nobody can live without a brain, Babies born with no brains is serious jobs for the doctors, getting brain-washed drains mist things out of the head, a special shampoo is the main part of brain washing, removing ANYTHING the shampoo touches around the brain, making it hard to remember it. So the answer to this question is: Yes! Sometimes no, surgens might have to.

What should be taken if there is a lack of serotonin?

Many doctors will purscribe SSRIs and SNRIs to treat serotonin deficiency but it is not a cure, just a bandaid and a poor one at that.

People with criticaly low serotonin levels are unable to benefit from the effects of SSRIs and SNRIs simply due to the brain's own inability to trigger the release of serotonin in any meaningful ammounts without outside stimulis (in my case due to heavy drug abuse in my youth).

What can a kid's brain do that an adult's can't?

Squat. Adults sit, or bend over...but they don't squat. Children can hear high frequency sounds that adults cannot. Most adults cannot hear tones above 13,000 Hz

What is a chronic brain cyst?

This may be something you have had most of your life. It is called a neoplasm (new growth). It can be filled with fluid, air, or brain matter. It cause dizziness, balance problems, seizures or nothing. Chronic means that you have had this a long time and it isn't new.

Can chlamydia cause brain damage?

Chlamydia can cause premature rupture of membranes and preterm labor, both of which increase the risk of cerebral palsy.

How does herniation of the brainstem occur?

Death or permanent debilitation follows herniation of the brain stem.
Such herniation will cause compression of those structures within the brain stem that control the most vital functions of the body (breathing, heart beat, consciousness).

A person who has suffered damage to her amygdala?

hum they are damages that are horable and not good at all.

Does radiation cause brain tumors?

It is possible. Studies have shown that workers who are regularly exposed to radiation are much more likely to develop brain tumors later in life. However this is not the only factor and it is not really known for certain what causes most brain tumors.

What does dopamine do for the brain?

Dopamine is a Neurotransmitter as well as a Neurohormone. Its secretion is linked to increased heart rate and blood pressure. As released by the hypothalamus, it acts as an inhibitory hormone which stops the anterior pituitary gland from releasing prolactin. The lack of this Neurotransmitter causes several conditions, the most well known being Parkinson's Disease. An excess of this neurotransmitter has been linked with several psychiatric conditions such as schizophrenia, autism, and ADHD.

Why are kids more imaginative than adults?

Children have a good imagination, because they don't care about what others think. they think of what, in their mind, goes together with the situation, or things they have experienced or watch happen. such as the game: Mommy and daddy, or going to the gas station. and they just pretend like things are what they want them to be. they are not embarassed by anything.

Can epilepsy cause brain damage?

The question here was "CAN epilepsy cause brain damage?" The answer is an unequivocal, "YES, it can" Frequent and/or prolonged seizures can indeed cause brain damage. However, most people that have Epilepsy are properly diagnosed, treated and monitored, so medication can assist them to live normal lives and reduce this risk. Often someone who has Epilepsy has it as a result of damage to the brain, like a traumatic head injury in something like a car accident. Unfortunately, undiagnosed or untreated epilepsy -- or poor compliance with medications and treatments --- can trigger a seizure which could cause a car accident. For that reason, anyone who has had a seizure must surrender their driver's licence until it no longer presents as a hazard. There are specific guidelines available from the State or Provincial Departments of Transport in your area.

Is the midbrain part of the brainstem?

Yes, it is where the spine enters the brain and includes the medulla oblongata, the pons and the tegmentum. Parts of the basal ganglia are also present in the brain stem. Respiration and heart function is controlled by the medulla. The pons is the relay of motor system impulses from the body and brain through the cerebellum. The basal ganglia is involved in motor function initiation and the inhibition of unnecessary motor impulses.

Is the brain constantly active whether a person is asleep or awake.?

True. Brain wave activity changes from the waking state through the various stages of sleep, but the brain is active all of the time. When the brain is no longer active at all, death is at hand.

What is involutional changes of the brain?

Evolutionary changes in the brain happens with age. It is a normal process that occurs starting around the fourth decade and progressively happens. Although all life spans are not the same so the predictable evolutionary changes vary.

  • Epstein-Barr virus (EBV)

  • HIV
  • herpes simplex
  • herpes zoster
