How Does Alcohol Make You Drunk?

As you know, I started university this year and since then I have made some embarrassing descisions as a result of alcohol consumption. Making this educational infographic about the science behind drunkeness balances it all out right..?

Fun FMA manga fact: This isn’t mentioned in Brotherhood, but the reason Roy and Riza came to Resembool scouting out the Elrics is because someone fucked up the ages on Ed and Al’s file. Literally Roy and Riza are riding in the back of some horse-drawn carriage into Resembool chatting with the driver like “yes we’ve heard rumors of two alchemist brothers here, Ed and Al Elric ages 31 and 30 respectively. Do you know where they live?” And the driver pretty much answers with “lol what? Those kids are like 10.” Except now Roy and Riza are already THERE so they decide “Fuck it. Let’s pay a visit anyway.” So everything that went down in the series is thanks to some mysterious fuck up in the Amestrian Intelligence Department and I salute that person.

“When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.”

-Nikola Tesla, 1926

The world’s most detailed scan of the brain’s internal wiring has been produced by scientists at Cardiff University.

Not only does the scan show the direction of the messaging, but also the density of the brain’s wiring. Conventional scans clearly show lesions - areas of damage - in the brain of MS patients.But this advanced scan, showing axonal density, can help explain how the lesions affect motor and cognitive pathways - which can trigger movement problems and extreme fatigue.

Prof Derek Jones, CUBRIC’s director, said it was like getting hold of the Hubble telescope when you’ve been using binoculars. “The promise for researchers is that we can start to look at structure and function together for the first time,” he said.

How the food you eat affects your brain

If you sucked all of the moisture out of your brain and broke it down to its constituent nutritional content, what would it look like? Most of the weight of your dehydrated brain would come from fats, also known as lipids. In the remaining brain matter, you would find proteins and amino acids, traces of micronutrients, and glucose. The brain is, of course, more than just the sum of its nutritional parts, but each component does have a distinct impact on functioning, development, mood, and energy. So that post-lunch apathy, or late-night alertness you might be feeling, well, that could simply be the effects of food on your brain.

Here are four fascinating facts about your brain on food!

Your brain runs on fats! The good kinds, that is. As we mentioned before, your brain is made mostly of fats. Of the fats in your brain, the superstars are omegas 3 and 6. These essential fatty acids, which have been linked to preventing degenerative brain conditions, must come from our diets. So eating omega-rich foods, like nuts, seeds, and fatty fish, is crucial to the creation and maintenance of cell membranes.

Food can make you super sleepy! But, it can also keep you up. Proteins and amino acids, the building block nutrients of growth and development, manipulate how we feel and behave. Amino acids are one of the reasons we might feel calm after eating a large plate of pasta, or more alert after a protein-rich meal. While the human brain only makes up about 2% of our body weight, it uses up to 20% of our energy resources. Most of this energy comes from carbohydrates that our body digests into glucose, or blood sugar. The frontal lobes are so sensitive to drops in glucose, in fact, that a change in mental function is one of the primary signals of nutrient deficiency. Carbs come in three forms: starch, sugar, and fiber. While on most nutrition labels, they are all lumped into one total carb count, the ratio of the sugar and fiber subgroups to the whole amount affect how the body and brain respond. A high glycemic food, like white bread, causes a rapid release of glucose into the blood and then comes the dip. Blood sugar shoots down, and with it, our attention span and mood. On the other hand, oats, grains, and legumes have slower glucose release, enabling a steadier level of attentiveness. For sustained brain power, opting for a varied diet of nutrient-rich foods is critical.

Trans fats are not your friends. While omegas are good fats for your brain, long-term consumption of other fats, like trans and saturated fats, may compromise brain health. Some research shows that trans fats may impair your memory and may actually affect the size of your brain??!?

Food affects your mood. The complex combinations of compounds in food can stimulate brain cells to release mood-altering norepinephrine, dopamine, and serotonin. But getting to your brain cells is tricky, and amino acids have to compete for limited access. A diet with a range of foods helps maintain a balanced combination of brain messengers, and keeps your mood from getting skewed in one direction or the other.

How’s that for ‘food for thought’?

Ravenclaws love and hate ambient noise. It needs to be a specific kind of noise depending on what they’re doing, and if it varies too far from the ambient noise they wanted, they just find it distracting.

Pay attention to the slight movements of your eyes as you think about your favourite childhood cartoon character. Or a song you’re sick of hearing. Imagine how you may look in 20 years time. Your favourite ice cream flavour? It’s likely your eyes shifted slightly as you thought because your eye movements are linked to certain areas of your brain. Someone trying to lie about a made up conversation may shift their eyes to the left or someone having an internal debate may have their eyes cast downwards to the right.

Of course, this is not completely foolproof as our eyes are constantly moving and are affected by a number of environmental stimuli such as light, sound or even pressure to maintain eye contact in a conversation but this serves as a general guide.
