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 a human brain think more or can a frog's brain?
A frogs brain is different than a humans beacuse they think about different things than humans do and they have a smaller brain with alot more blood cells, but humans have lots of blood cells too.
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.
What causes inflammation of the brain?
One is west nile virus, caused by mosquitoes.
There are more than a dozen viruses that can cause encephalitis, spread by either human-to human contact or by animal bites. Encephalitis may occur with several common viral infections of childhood. Viruses and viral diseases that may cause encephalitis include:
- mumps
- Epstein-Barr virus (EBV)
- cytomegalovirus infection
- HIV
- herpes simplex
- herpes zoster
- herpes B
- polio
- mosquito-borne viruses (arboviruses)
Which cranial nerve is involved with listening to music and sea sickness?
Vestibulocochlear nerve (CN VIII). More specifically vestibular nerve of CN VIII is responsible for equilibrium and balance.
How does the brain tell from which direction a sound comes answers.com psychology?
The brain picks up the vibrations from the sound waves. It would be like if your phone vibrated on you in your pocket, you could immediatly tell where it was coming from, right?
What role does memory play in your lives?
We have two types of memory. One, is long term. This is the memory when you learn the times tables,or a phone number. The other is short term memory. This is for information that you need for a short time and then not use. At various times in our lives our memory clears itself to make room for new memory. Think of the brain like a computer and our memory is one of the motherboard parts. We need memory for learning, to know who we are, and to know family and friends.
Do smarter people have bigger brains?
No, a bigger brain usually means just a bigger head. We can only access 21.099% of our brain and "that persons brain writes stuff in a bigger font".
Answer #2: Answer #1 is a bit dubious. There is no set percentage of our brain that we use or access. We use what we need, when we need it, and one objective cannot use 100% because that would mean neurons would have to move around. A neuron in your motor cortex cannot process sensory input. We also often utilize the vast majority of our grey matter (The part of the brain that handles the most processes) and most parts of the brain are constanty active. Doing any task often requires most parts of the brain to be active and processing information like sensory input, reasoning, motor control, etc. Even while sleeping, parts of your brain are processing and figures estimate about 15% is the baseline for sleeping. If you were able to use 100% of your brain at any one moment, you would go into a seizure. The myth of a fixed percentage, be it 10%, 21% or whatever is perpetuated as a reason for psychic powers but is completely false.
That said, the answer is debatable and depends on who you ask. Take someone like Einsten for instance. He was a genius with an IQ of at least 150. His brain is normal size for a human brain yet has many more neurons than an average human, he (supposedly) stated that he believes that neurons are the difference, not size. The truth is we don't really know but all evidence points towards no, a large brain does not mean more intelligent and that it comes down to neurons. More neurons = more intelligent.
A reduction in the strength of a signal, the flow of current, flux, or other energy in an electronic system.
