What in the brain is responsible for wakefulness?

User Avatar
The reticular formation is a part of the brain that is involved in actions such as awaking/sleeping cycle, and filtering incoming stimuli to discriminate irrelevant background stimuli. It is essential for governing some of the basic functions of higher organisms, and is one of the phylogenetically oldest portions of the brain.

If your wife's judgment is often impaired by brain cancer how do you convince her to not do anything dangerous or irrational?

User Avatar
I am sorry to say that there isn't much you can do at this point. Please keep in close contact with your doctor and perhaps there is a medication that can subdue this behavior to some degree depending on the severity of the cancer. If possible it is advisable to have someone stay with your wife constantly, and if she is still persistent then there is no other alternative, but to see your doctor and have your wife admitted into hospital for her own protection.

What does the idiom 'on cloud nine' mean?

User Avatar
To be on cloud nine means to be blissfully happy. See the Related Link for how this phrase came to be part of our language. More Information According to the "Morris Dictionary of Word and Phrase Origins," the phrase is based on U.S. Weather Service terminology. This theory holds that cloud types are numbered, and that "cloud nine" is the designation given to "cumulonimbus" clouds, the highest-flying clouds around, making them an apt metaphor for being "on top of the world." When "you're on cloud nine" you feel wonderful ! Like nothing else is really very important. Cloud nine is a fictitious place said to be similar to heaven. This expression means that you are extremely happy, almost in heaven. For example: You have been dating for 6 weeks and you are madly in love with him and he proposes to you and you are in static, or ''on cloud nine" OR: If you have been dating for 6 weeks and you are madly in love with her and propose to her and she accepts without hesitation, you are blisfull and elated or "on Cloud Nine". There is also a software called Cloud9 On top of the world

What is foci of T2 hyperintensity in the subcortical and periventricular white matter?

User Avatar
This phrase is a statement that would be used by a radiologist when reviewing the results from a MRI. Breaking down the phrase by individual parts: T2 - An indication of the type of scan that was done. In a T2-weighted scan, areas that are fluid-filled appear bright, while areas that are fatty appear dark. A T1 scan would show the opposite results. Hyperintensity - An indication of a bright region on the scan. Foci of T2 Hyperintensity, therefore, means "focal points, or concise areas, of very bright spots." Subcortical and periventricular white matter - These are locations within the brain. Regions of the brain are categorized by color (white matter or grey matter) and location (cortical, or related to the cortex, subcortical, or below the cortex, etc). The statement, therefore, means "white spots on a MRI scan at certain locations within the brain." This statement alone does not indicate any particular disease is present. It is a piece of information that a neurologist would use to help determine whether or not someone had a certain disease or condition. There are many conditions or diseases which can cause white spots on the brain; only a neurologist can sort through the possibilities and determine what caused these white spots.

How many cells are in the human brain?

User Avatar
Over 400,094,800 cells is the answer listed here, which appears to be completely incorrect. A quick Google search found a consensus around the 100,000,000,000 mark. Here are the sources. Glencoe Health 2nd Edition. Mission Hills: Glencoe Inc., 1989: 252."Weighing around three pounds (1.35kg), the brain contains nearly 100 billion cells."100 billionWorld Book 2001. Chicago: World Book Inc., 2001: 551."The human brain has from 10 billion to 100 billion neurons."10-100 billionMagill's Medical Guide Revised Edition. Salem Press, 1998: 221."It has been estimated that the adult brain has around one hundred billion neurons and an even larger number of glial cells."100 billionThe Science Times Book of the brain. New York: The Lyons Press, 1987: 150."The human brain holds about 100 billion nerve cells."100 billionThe Scientific American Book of the Brain. New York: Scientific American, 1999: 3."An adult human brain has more than 100 billion neurons"> 100 billion Please note that "the answer listed here" - over 400,094,800 - refers to the number of cells in the human brain. The 100 billion figure, mentioned repeatedly in the sources quoted above, refers to neurons or nerve cells, which are only one kind of brain cell. As indicated by the 3rd cited source, neurons are actually thought to comprise less - far less, according to most authorities - than 50% of the total. (Glial cells are the most numerous.) So 400,094,800, while an improbably specific number, could well be close to the mark. the brain has about 1 billion cells

Cerebral dysgenesis hypotonia?

User Avatar
Cerebral Dysgenesis is a nondescript term that describes improper brain development in utero. It is used oftentimes when no specific diagnosis can be made. That being understood, it can usually be detected at birth on a sonogram by 20 weeks. Prognosis and manifestation is varied, but may range from moderate debilitation to severe, with symptoms that may include paralysis, moderate to global mental retardation, high or low muscle tone, clonus, seizures, feeding difficulties, blindness, deafness and impairment that ranges from delayed milestones to global delays. Cerebral Dysgenesis means "lack of brain development" Agenesis is the worst stage of the condition. This can be characterized by absence of portions of the brain tissue, with the resulting space being filled with cerebral spinal fluid. Since there is a great range of severity, each individual case must be treated as unique. Many of the most globally affected children with this disorder display an ability to enjoy life and respond to love and attention. The milder cases can walk, talk, eat and perform simple tasks. Care taking can be very involved, but the humanity of each individual must never be overlooked. The individual potential for development along the lifespan is totally unique to each person, depending upon the degree of functioning brain tissue available and the extent to which brain tissue is utilized. Every child with this impairment benefits from physical, occupational and speech/language therapy. The life span of a child born with cerebral dysgenesis also varies with the degree of involvement and the ability or inability of the body to handle infections. If the lungs are affected due to lack of muscle tone, the ability to handle secretions or the inability to achieve a productive cough, pneumonia is an ongoing threat. The life expectancy of even a globally involved child can be many decades. Some children with cerebral dysgenesis do not survive past one year of age. Its very important for the parents of any special needs child to get help from the very beginning. There are many avenues for support available depending upon locale and can include: support groups, respite care centers, governmental funding for special needs day care, respite and therapy, among many others. Life with a disabled child can be very difficult, challenging, stretching, eyeopening and even heart wrenching. It can also be rewarding and the best job you'll ever have! There needs to be more awareness about this condition and support for families that contend with these congenital anomalies. Dr. F SpecialKidNurse

How is diaper fetishism related to depression particularly depression associated with major childhood trauma and feelings of abandonment?

User Avatar
The adult world does not allow this "dependence." Yet, many crave it, want it, desire to be young and innocent and safe. They don't have to do anything, but mind "mommy" or "daddy" and they will be okay. We all want to be loved. To be cared for. To be safe. Unfortunately, abuse and neglect takes this sense of safety away from some. It's not hard to conceive that a child's mind would imagine being an innocent, cute, little baby that will be loved regardless as an alternative to a reality where they are not loved or protected or safe. I'm not sure why this gets sexualized, but it doesn't really matter; sexual satisfaction is not the main course for the adult baby. It's being in the role, being safe, being controlled so that no decisions have to be made, other than to suck on a bottle or a pacifier. It is safety. It is being loved. It is being accepted unconditionally. Who wouldn't want that? Any person who had been abused or neglected will have their demons to conquer. Depression is a side effect of holding in one's own emotions. People who have been abused or neglected have learned that it is not safe to reveal their feelings, so they hide them inside -- even from themselves! Unfortunately, our creator made us to be feeling beings, and this loss of emotionally connectivity with our minds can easily lead to depression. It seems to me that being an Adult Baby is part of the solution of recapturing one's inner heart, and that depression is the result of NOT doing so.

Can higher octane fuel make an ATV more powerful?

User Avatar
With a stock engine it is best to use the octane grade of fuel recommended by the manufacturer. Gasoline has a fairly similar BTU value per gallon regardless of octane (unless it's oxygenated like VP2 or VP4). The higher octane does allow you to alter aspects of the engine such as CR and timing advance to produce more power because of its resistance to detonation/pre-ignition/detonation.

What happens if you miss your sol?

User Avatar
If you are referring to the musical note that comes after "fa" and before "la," it could make the song you are playing sound all wrong. But I wonder if you are referring to the "soul." Some people wonder if they have a soul; it is a concept that comes from religion and from certain philosophies. If you do not believe in this concept, then you would not be missing it. You would just think that you don't have a soul because it doesn't exist.

Where are memories stored in the brain?

User Avatar
There isn't a single exact location of memory storage. The process of encoding and retrieving memories is a complex one, requiring many structures to function. The hippocampus and prefrontal cortex are two major areas- however numerous other areas play a part. While these areas are integral to the process of encoding and retrieving, as to where memories are physically stored, there is no solid answer. Neurologists have done studies in which they teach a mouse a trick, then remove the right half of its brain, and it still remembers the trick (Though how they were able to keep the mouse alive with half a brain, I have no idea). Then, they remove the left half, and it still remembers the trick! The deduction is that the memory remains intact, independent of the functioning of any physical part of the brain. I have heard it concluded that ALL memory must exist in ALL parts of the brain equally at ALL times.

What are the 3 parts of the nervous system?

User Avatar
The human nervous system can be divided into three main parts: Central nervous system (CNS) *is composed of brain and spinal cord...* Peripheral nervous system (PNS) *is composed of all body nerves that lie outside of your central nervous system...* Autonomic nervous system (ANS) *controls the involuntary actions of your body organs...* Central nervous system: brain, spinal cord, and association neuron. Not know where they belong by me: ganglia, cranial nerves, potential difference, excitability, somatic motor nervous system, autonomic nervous system. Peripheral nervous system (I think) has sympathetic division, and parasympathetic division.

Asked in Health, Brain

Why does your brain have crevises?

User Avatar
They are called sulci (singular - sulcus). These are folds of the brain designed to give it more surface area. For a reasonable layman's definition of sulci, the Wikipedia article for 'Sulcus (neuroanatomy)' gives an introduction. (I'm a neuroscience student.) The brain uses the surface area to store information. This area is finite in size and when a person is born, its smoothe. As you age you need more space to store information and the brain makes ridges and valleys on the surface, thereby adding more pages for the book where we store memory.

What are visions?

User Avatar
Visions both come from and are about God, their understanding is given by God, and can only be understood and interpreted if a person has the Holy Spirit of God. They come at night when a person is asleep, and are frightening. They can appear to anyone, but in the Millennium everyone will have them. Visions come at night:- Gen 46:2 And God spake unto Israel [ie Jacob, before God re-named him Israel] in the visions of the night, and said, Jacob, ... Dan 7:7 After this I saw in the night visions, .... Dan 7:13 I saw in the night visions, and, behold, ..... Visions come when a person is asleep:- Job 4:13 In thoughts from the visions of the night, when deep sleep falleth on men Visions are frightening:- Job 7:14 Then thou scarest me with dreams, and terrifiest me through visions: Dan 4:5 I saw a dream which made me afraid, and the thoughts upon my bed and the visions of my head troubled me. Dan 7:15 I Daniel was grieved in my spirit in the midst of my body, and the visions of my head troubled me. Visions both come from and are about God:- 2Ch 26:5 And he [Uzziah] sought God in the days of Zechariah, who had understanding in the visions of God: .... 2Co 12:1 It is not expedient for me doubtless to glory. I will come to visions and revelations of the Lord. Visions can appear to anyone: - patriachs:- Gen 46:2 And God spake unto Israel [ie Jacob, before God re-named him Israel] in the visions of the night, and said, Jacob, ... -Kings:- Dan 2:28 But there is a God in heaven that revealeth secrets, and maketh known to the king Nebuchadnezzar what shall be in the latter days. Thy dream, and the visions of thy head upon thy bed, are these; -prophets:- Eze 13:16 To wit, the prophets of Israel which prophesy concerning Jerusalem, and which see visions of peace for her... -prisoners:- Eze 1:1 Now it came to pass..., as I was among the captives ... that the heavens were opened, and I saw visions of God. The understanding of visions is given by God:- Dan 1:17 As for these four children, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams. Visions can only be understood and interpreted if a person has the Holy Spirit of God, but if they don't it has to be explained to them:- Dan 4:9 O Belteshazzar [ie Daniel],... because I know that the is in thee, ... spirit of the holy godstell me [ie King Nebuchadnezzar] the visions of my dream that I have seen, and the interpretation thereof. In the Millennium everyone will see visions:- Joel 2:28 And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions: Act 2:17 And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
