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.

When I got the email from my kids’ middle school about a presentation called “Why teens shouldn’t drink; and how parents can make a difference,” I sighed, thinking, oh no, not another DARE, Just Say No talk.
For the longest time, the speaker, parenting expert Mike Nerney, didn’t even mention the word alcohol. Strip away the emotional charge, the fun, the kids-will-be-kids nostalgia for drinking and you end up with science.
First, Nerney talked about all the work that’s going on in the brain during the teenage years—namely, 200 billion cells are starting to connect.
The most striking thing Nerney explained is this: When it comes to alcohol, teen brains and adult brains are worlds apart.
When you’re an adult, alcohol gets into the pathways and calms them down, making you feel better. Nerney believes that the drinking age should be 24, because that’s when the body is actually ready to handle alcohol. Drinking erodes parts of your brain—the parts that make you smart, such as the prefrontal cortex and the hippocampus. The key, Nerney says, is to delay the onset of alcohol use long enough for teens’ brains to develop. The other key is to verbalize to your kids that alcohol is dangerous—for their brains, and for their safety. Finally, the best thing we can do for teens, Nerney says, is to offer them thrilling alternatives to alcohol that satisfy their need for risk-taking and novelty. Drinking DiariesWe drink for different reasons: to quench thirst, to loosen up, because it tastes good, to enhance a meal, because we're addicted, as part of a ceremony, to celebrate, to mourn. This is a place where women can spill their drinking stories--from lamp-swinging hilarity to bottle-under-the-bed despair.
As Seen on ABC News NowCaren Osten Gerszberg, Drinking Diaries co-founder, is interviewed as part of a discussion on women and drinking.

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.
If you’ve ever seen kids pound beers at Spring Break, you’ll understand how much alcohol reenergizes their brains, and gives them a powerful sense of entitlement.
He cited research by the American Medical Association, and studies at Duke University, in case we wanted scientific proof.
Luckily, the brain is neuroplastic, and once you stop drinking, you can recover those parts that were lost. If you approach drinking in terms of brain development, rather than a vague lecture that they equate with killing their joy, you might have more success reaching teens.
We think they’re not listening, but somewhere deep down inside, they’re actually internalizing our values. At DRINKING DIARIES, you will read, and be able to share the details, the deep questions, the wide and wild range of experiences that pertain to women and alcohol.
If you ask an adult to set their hair on fire, they’ll immediately synthesize everything into a hell no, whereas a teen will actually consider it (hmm, that might be cool.
And then there are the non-drinkers, for whom abstaining may be as much of an issue as drinking.
