When you eat, that food is broken down and the process of respiration allows for you to convert that food into an energy form that can be used by your body. In addition to providing the body with Oxygen, it’s also responsible for getting rid of Carbon Dioxide, which is a waste product that is made in the body.
Now that we have that covered, let’s talk about the involvement of the brain in this process.
The medulla oblongata is involved in regulating many of the bodily processes that are controlled automatically like blood pressure, heart rate and yes, you guessed it . It can then send nerve impulses to muscles in the heart and diaphragm, letting them know that they need to either step up their game, or slow down a bit. The reason I mentioned the heart is because the respiratory system is very much tied to  the circulatory system.
When you are exercising, you are using your muscles in a significant way, and your body demands that you take in more oxygen so that it can be delivered to your muscles.
You circulatory and respiratory system needs to make sure that the oxygen is getting to the muscles faster than when you are just chilling. In order for that process to happen efficiently, the medulla oblongata, after sensing what is happening, sends signals to the heart and the respiratory muscles (diaphragm and intercostal muscles). New research reveals that brain damage affecting the insula a€“ an area with a key role in emotions a€“ disrupts errors of thinking linked to gambling addiction.
During gambling games, people often misperceive their chances of winning due to a number of errors of thinking called cognitive distortions.
There is increasing evidence that problem gamblers are particularly prone to these erroneous beliefs. For the study, the researchers gave patients with injuries to specific parts of the brain (the ventromedial prefrontal cortex, the amygdala, or the insula) two different gambling tasks: a slot machine game that delivered wins and 'near-misses' (like a cherry one position from the jackpot line), and a roulette game involving red or black predictions, to elicit the gambler's fallacy.
All of the groups with the exception of the patients with insula damage reported a heightened motivation to play following near-misses in the slot machine game, and also fell prey to the gambler's fallacy in the roulette game.
Clark added: "Based on these results, we believe that the insula could be hyperactive in problem gamblers, making them more susceptible to these errors of thinking. Gambling is a widespread activity: 73% of people in the UK report some gambling involvement in the past year* and around 50% play games other than the National Lottery. With the help of a rat casino, University of British Columbia brain researchers have successfully reduced behaviours in rats that are commonly associated with compulsive gambling in humans. A new study led by the University of Exeter and Swansea University has pinpointed the changes in the brain that lead gamblers to react in the same way to near-misses as they do to winning.
Homeless people are ten times more likely to be problem gamblers than the UK population as a whole, researchers at Cambridge have found. Postpartum depressiona€”a household term since actress Brooke Shields went public in 2005 about her struggle with ita€”is indeed serious. Whether you're Van Gogh or a stick-figure sketcher, a new Drexel University study found that making art can significantly reduce stress-related hormones in your body. Sad music can provide enjoyment, comfort or pain to different people, according to new research looking at the effects of melancholy songs on the emotions.
A new Finnish study shows that fetal exposure to commonly used SRI drugs may affect brain activity in newborns. Different parts of the brain do different things, but there’s more overlap than you might think. If I had been asked 15 years ago to write a short piece about what the different parts of the brain did, it would have been a fairly straightforward task. Over the last 15 years, the methods used to study the brain have advanced significantly, and with this so has our understanding. The structural anatomy of the brain is certainly well defined and the more basic of our functions have been generally well mapped.
As we move to the “higher levels” of the brain, namely the cerebral cortex, where more complex functions come into play, the assignment of function to structure becomes decidedly less distinct. The cortex is structurally divided into two hemispheres (left and right) each with four lobes (occipital, parietal, temporal and frontal).
This has led to a number of misnomers regarding brain function, the most popular of which is the commonly held belief that there is a distinction between the left “logical” brain and the right “creative” brain. The conceptualisation of an almost one-to-one relationship between structure and function was largely a result of lesion studies, where damage to a specific part of the brain resulted in impairments in a particular function. We have come a long way from the phrenology of Franz Gall in the 19th century, in which characteristics such as secretiveness, self-esteem and wonder were determined by the shape of the skull (thought to be a proxy of brain size), and the 20th century reliance on lesion studies to determine the function of the different areas of the brain. We are now developing an understanding that complex, higher-level brain functions are a result of a number of brain areas working together, in what are termed “networks”.
This has been a result of techniques such as Magnetic Resonance Imaging (MRI), which allows us to look at the entirety of brain regions involved in certain functions, with newer applications allowing the visualisation of connections between these brain regions (i.e.
Simplified depiction of the models of relationship of brain structure to function based on phrenology, lesion studies and neuroscience.
To conceptualise this, you could think of the brain as a exceptionally efficient rail network where certain train stations perform specialised duties but they do so in conjunction with other stations, and they are connected and “communicate” via the rail network. There are specific regions in the dominant (usually left) hemisphere that are integral in the production and comprehension of speech, i.e. But the non-dominant (usually right) hemisphere is also involved in language, and is thought to be important in the recognition and production of the emotional context of speech. Additionally, the “language network” involves a number of other dominant “left” hemisphere regions, including prefrontal cortex, premotor cortex, supplementary motor area, as well as regions of the parietal and temporal lobes. These brain regions work together to perform higher order aspects of language such as the application of the correct syntax to speech, as well as the mapping of words to their meaning.


While there are certain highly-specialised brain regions for language, they are still part of an extensive network of brain regions which work together to produce this complex function. According to research, players like Spain’s Andres Iniesta have superior cognitive skills to less successful players. The Central Nervous System (CNS)The CNS is responsible for taking in information through the senses, motor function, thinking, understanding, and reasoning. This summary provides information about the role of different parts of the brain and how alcohol affects their functioning. Cerebellum: This part works with the primary motor cortex to control movement, balance, and complex motor functions. Reticular activating system: This part is in the midbrain, and it controls sleeping and waking.
Alcohol Can Be DangerousYou can see that alcohol affects just about every part of the brain and the nervous system. Sometimes, too, people become so dependent on alcohol that they can't function properly unless they drink frequently. As people continue to drink heavily, their brains get used to alcohol, or develop a tolerance for it.
The highest rates of alcohol abuse are reported among young people in their late teens and early twenties. New research indicates that binge drinking may last beyond a couple of parties where teens may have indulged. Alcohol abuse can lead to major health problems—and can affect your ability to learn and function well.

Your brain starts where the spinal cord enters the skull, and the first section that you encounter is called the Brain Stem. The medulla oblongata basically detects carbon dioxide (CO2) and Oxygen (O2) levels in the bloodstream and determines what changes need to happen in the body. The research, led by Dr Luke Clark from the University of Cambridge, was published today, 07 April, in the journal PNAS. For example, 'near-misses' seem to encourage further play, even though they are no different from any other loss. In this study, the researchers examined the neurological basis of these beliefs in patients with injuries to different parts of the brain.
For the control groups, they also had patients with injuries to other parts of the brain as well as healthy participants undergo the gambling tasks. For a small proportion of players (around 1-5%), their gambling becomes excessive, resulting in features seen in addiction. The researchers suggest that the effects of drugs on fetal brain function should be assessed more carefully. Children don't seem to think so, like adults and babies, children think the uglier you are, the less trustworthy you are.

The “lower levels,” such as the brainstem, regulate functions such as heart rate, breathing, and maintaining consciousness. While it was thought that this was its sole function, more recently the cerebellum has also been shown to have a role in so-called “higher functions” such as cognition and emotion.
As discussed below, such complex behaviours are not determined by a specific brain region, or even a specific hemisphere.
But as our techniques of assessing the brain became more sophisticated this approach was shown to be somewhat simplistic. Rather, while there are brain regions that carry out specialised functions, they are now thought to do so in concert with other brain regions via network connections. Language is often thought of as a solely “left brain” function and, while there is a degree of lateralisation, this is certainly not the whole story. It enables you to run and play, learn new facts and ideas, and feel a wide range of emotions. The CNS is made up of billions of neurons, or nerve cells, in the brain and the spinal cord.
That means that alcohol makes nerve cells in the brain less excited, causing them to slow down. How much, and how fast, a person drinks are important, as is whether other drugs, such as marijuana, have been taken. Researchers used to think that development only took place during the first few years of life. In a young person, drinking too much alcohol can affect those connections, which are not finished developing yet.
Alcohol can reach and enter these cells and damage, or even, at high enough levels, kill them.
At even higher levels, it can shrink the vessels and increase blood pressure, exacerbating such conditions as migraine headaches. As different parts of the brain "shut down" from alcohol abuse, teens may engage in behaviors that are not good for them.
Because the prefrontal cortex is not mature, alcohol can harm a teen’s ability to reason and weigh choices.


Research points to a relationship between early onset of drinking and later alcohol-related problems.
Susan Tapert, a neuroscientist at the University of California, San Diego, studied the effect of binge drinking on developing adolescent brains.
Cells use this oxygen in order for metabolism to take place and without it, you would have no energy. In a random sequence like tossing a coin, a run of one event (heads) makes people think the other outcome (tails) is due next; this is known as the 'gambler's fallacy'. Problem gambling is associated with both debt and family difficulties as well as other mental health problems like depression. The brain can process information gathered through the five senses—seeing, hearing, smelling, tasting, and touching. The peripheral nervous system, which includes neurons, forms a network that carries information to the neck and arms, trunk, legs, skeletal muscles, and internal organs. That's because alcohol can pass through the blood-brain barrier, reaching neurons directly. New findings, however, have shown that during the teen years and into a person’s twenties, important changes are taking place.
As a result, teens may do impulsive things that they probably would not do under normal circumstances. Even a small amount of alcohol can make teens forget what they did or learned while they were drinking.
During heavy drinking, these may slow or stop working altogether, endangering an individual’s life.
Instead, teens may do something simply because it is fun or feels good.Take risks they would not usually take. Throughout the nervous system, what is happening is that the alcohol is causing the nerve cells to slow down.
High-school and college students may engage in binge drinking, which is defined as having 4-5 drinks over a two-hour period.
She gave the group different kinds of tests measuring the ability to perform certain tasks. But they are continuing to study the effect of binge drinking on teens, so they should know the answer soon. There is even a part of the brain that makes sure that vital life processes, such as breathing and maintaining a regular heartbeat, go on, even when you are asleep. If alcohol abuse runs in your family, then you are at greater risk for having problems with it, too.The BrainThe brain is made up of more than 100 billion neurons. For example, parts of the brain that help teens make decisions, regulate emotions, and control their impulses are still forming. This is also the part of the brain that is affected first, causing behavior to become looser and less guarded. Alcohol may affect emotions, leading to crying, fighting, or a desire to be close to another person. Because connections between the prefrontal cortex and the ventral striatum are still maturing, alcohol can affect those connections.
For example, alcohol mixed with Ritalin may damage a teen’s ability to perform tasks that require total concentration.
In 2003, the average age of first use of alcohol was about 14, compared to about 17½ in 1965.
What was particularly interesting about her findings is that they were different for girls and boys. That's because the first areas affected by small amounts of alcohol are those involved in inhibiting behaviors, which can cause an increase in animation, an increase in talkativeness, and greater sociability. In fact, many characteristics of adolescence, such as mood swings, may be, in part, a result of brain development. As a result, teens may do impulsive things, such as drinking and driving or having unprotected sex. Large amounts of alcohol mixed with lithium may impair judgment, thinking, and motor skills.
Those individuals who reported starting to drink before the age of 15 were four times more likely to also report having signs of alcohol dependence at some point in their lives.
Girls performed less well on tests measuring spatial functioning, such as the ability to copy a difficult puzzle. Alcohol can damage or even kill neurons, perhaps changing development of those parts of the teenage brain that are still developing. New research shows that serious drinking problems (including what is called alcoholism) typically associated with middle age actually begin to appear much earlier, during young adulthood and even adolescence. Over time, the brain pushes the nerve cells to such a point that they need alcohol in order to slow down and function properly.
The difference was about 10 percent, which could translate into the difference between an A or a B.
