The removal of a bone flap near the skull in order to access the brain.
Lol. Technically, sure if you're in a fire, or too close to the Sun. Otherwise, no. However, you can lose connections between cells within the brain that "zap" info to other parts of your brain that make you respond. This happens with age. It is believed that long term marijuana smoking does this. Science has shown that you can improve the connections with different brain exercises, such as improving memorization skills (numbers, letters, and object placements), concentration kinds of games, and other knowledge builders.
Is the hypothalamus in the forebrain?
Good question, in order to solve this question lets look at the functions of the hypothalamus:
- The Hypothalamus controls your body's internal organs and ANS (autonomic nervous system)
- It also regulates the pituitary glands ( which are responsible for things like water concentration in your body and thyroid)
- The Hypothalamus also controls and maintains body temperature, blood pressure, and water levels ( done through the pituitary glands)
-it also controls thirst,hunger, and sex drive and produces hormones like aDH.
I guess when you look at all the functions of the hypothalamus without it you'd be dead in no time, therefore, I'd say you could classify it as the brain of the brain in conjugation with the medulla oblongata (which is a part of the brain responsible for breathing and heart rate)
What is foci of T2 hyperintensity in the subcortical and periventricular white matter?
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.
Which part of the brain controls mental processes?
The medulla oblongata is located at the base of the brain and controls breathing, heartbeat etc.
What are some methods for studying the brain?
Living brains are studied by means of an MRI (Magnetic Resonance Imaging) and dead brains are studied by means of autopsy. Countless different experiments are in progress to explore different aspects of neurphysiology, neurochemistry, and neuropsychology.
How long can a brain dead person live?
Sadly while their body can continue to go on with the help of machines, their mind, their personality, and all other parts of them mentally are already gone. Once a doctor has pronounced a person brain dead he is sure of his findings and this is something that cannot be reversed. There is no blood flow in their brain and their brain does not react in any way to stimulation. A quick way to see if someone may be brain dead is shining light into their eyes; a person who is truly brain dead does not have a pupil response. Eventually this person who is brain dead is let off of machines which keep their body alive and their body dies as well. Hopefully, if the person is able to give organ donations they do so, because they could be saving other's lives.
What is the role of the thalamus in hearing vision taste and smell?
It is the part of the brain whose function includes relaying sensation, special sense and motor signals to the cerebral cortex, along with the regulation of consciousness, sleep and alertness.
It acts as a kind of railway signal box. As information comes in through the senses, it goes directly to the thalamus and it sends the signals off to different parts of the railway yard (brain). It will send the signal to the cortex, or rational part of the brain and to the limbic or emotional brain at the same time. Although the limbic system will react to the stimulus a lightning split second quicker than the cortex, often sending people into flight or fight when it's not really appropriate in the present circumstances.

1. Thalamus acts as a relay station for both afferent and efferent fibres of the cerebral cortex. ]
2. Along with the hypothalamus, it helps in sleep and wakefullness.
3. Along with the cerebellum & basal ganglia, it helps in maintaining body posture.
The thalamus is a by-station from the sensory organs to the cerebral cortex sensory regions. It has a somatosensory mapping of the body and has known integrative functions.
There is also a part of the brain called the hypothalamus. It is the "leader" of the endocrine system. It controls what and where the hormones do and go and when they go at a certain time

One of the functions of the thalamus is to relay sensory information by transmitting axons to other regions of the cerebral cortex. Such as: the sense of touch is relayed to the parietal lobe, the sense the sight is relayed to the occiptal lobe, the sense of hearing is relayed to the temporal lobe, and the sense of balance is relayed to the cerebellum. The thalamus does NOT relay the sense of smell to the temporal lobes though.

The thalamus is the gateway to the brain that is responsible or receiving almost all incoming sensory information before the information reaches the cortex. Axons from every sensory system, except for olfaction, synapse in the thalamus as a last pit stop before the information reaches the cerebral cortex.
The functions of the thalamus include relaying sensory and motor signals to and from the cerebral cortex, regulating consciousness, sleep, and alertness.

A small glandular organ that is situated behind the top of the breastbone, consisting mainly of lymphatic tissue and serving as the site of T cell differentiation. The thymus increases gradually in size and activity until puberty, becoming vestigial thereafter.
It relays information from different parts of the brain.
it is part of your brain. it is the relay for sensory impulses. it shows what is pleasant and unpleasant.
The thalamus is a major relay center. All incoming sensory information except smell goes through the thalamus, before reaching the cerebral cortex. (And even smell has a pathway connecting to the thalamus.) The actual processing of the sensory information starts here, this is especially true about vision. It also participates in the regulation of sleep, arousal and wakefulness, and plays a role in motor functions as well.
Can permanent brain damage be caused from minor meth use?
No sh!t! If this is your question, it may be a sign. Stop using meth stupid.
What kind of answer is that? How ignorant that response is. Signs of brain damage by the same as someone who has experienced a stroke, slight, to severe depending on length of use, and amount used and other variables. Facial ticks, involuntary movement of the fingers, hands and feet.
What is the function of the human brain?
Your brain retains (does not control) everything about you. Your interests, personality, skills, thoughts, memories, emotions, breathing, heart beats, and just about everything your body does! The brain processes everything that you tell it, consciously or subconsciously, to process. An ultimate, unreplicable computer. Without the influences of a spirit it can do nothing at all.
What happens when one side of the brain is dead?
The brain is like software for a computer. once everything is working OK then there's no problem. The brain however, is much more sophisticated, in that different sides of the brain controls different aspects of the human body: mentally, physically and psychologically. However, if the left side of the brain is dead, it does not mean partial loss of 'functions', but total incapacity of the entire human body
What are some things that can result from an injury on your brain?
There two main categories for brain injuries are traumatic and acquired brain injury. Within these categories, here are five possible injuries: Traumatic includes concussions and shaken baby syndrome. Acquired brain injury is created by a loss of oxygen from such things as choking, electrical shock and trauma to the head.
What happens if we used 100 of our brain?
We actually use 100% of our brains all the time. The 10% usage of the brain is just a myth that was propagated by the media,
If you are out in high humidity, high heat, for a prolonged period you can get heat stroke. That's one way your brain can overheat. Another way it can overheat is if your temperature reaches 104 to 106 degrees from a virus.
What do the hemispheres in the brain control?
The left hemisphere of the human brain controls language, and thinking skills, and the right hemisphere controls all motor functions.
Any thought that person has is derived from the left hemisphere of that person's brain. If a person is speaking, the words are being formed in the left hemiphere, but in order for the mouth to open and for the tongue and lips to move in order to be able to speak the words, the right hemisphere needs to work.
If a person picks up a ball and then throws it, that person's brain's right hemisphere was working. A person reaches out and touches a pan. The pan is on the stove and is very hot, and when the person touches it, that person's hand jerks away from it. The arm reaching out to touch the pan was a voluntary action, but the hand jerking away was a reflex, which is an involuntary action.
Involuntary actions or movements are not controlled by the brain at all. A reflex is when the nerves detect something harmful (i.e. skin contact to a hot object, or cutting one's self against something sharp accidentally) and the nerves in the spine detect the nerve impulses and automatically send a new impules to the motor nerves of the muscle that can move the body away from harm (i.e. the hand touching something hot and then being jerked away).
Can anaphylactic mishap caust Traumatic brain injury?
Yes if your throat swells shut and your brain is without oxygen for long enough.
The medulla oblongata is responsible for regulating your rate of breathing, your heart rate, blood pressure, circulation and digestive system activity. It controls when these activities start, when they stop and how fast they go. This area is also where your sleep cycles are regulated.
What are the parts of the brain and what do they do?
The frontal lobe
This part of the brain controls decision making, problem solving, your behaviour, consciousness and emotions.
The parietal lobe
This lobe receives and processes sensory information about the different parts of the body. This is also where letters form words and words turn into thoughts.
The temporal lobe
This part of the brain is in charge of memories, emotions, hearing, language and learning.
The occipital lobe
This part of the brain is in charge of anything relating to vision .
The primary motor cortex
This part of the brain is responsible for regulating voluntary movements.
The primary sensory cortex
This part of the brain is part of the parietal lobe and takes information about the different parts of the body
The cerebellum
This part of the brain is in charge of balance, posture and movement .
