Things You Never Knew About Your Brain

I'm the engine that keeps you running all day long, and I'm here to share the mysteries of how I really work.

100 Billion Nerve Cells

So you might want to take a moment before you blame me for not being fast enough, failing to get easy math right, or even forgetting your friend's birthday. It's not really my fault: Information travels through me between the rates of 0.5 metres per second and 120 metres per second. Even though I weigh about three pounds, I'm a fuel guzzler that uses 20% of your body's energy.

Laughter Really Is The Best Medicine For Me

My amygdala and hippocampus (two parts linked to depression) light up when I hear laughter, as does my nucleus accumbens, which is a key player in pleasurable feelings. Chuckling reduces stress hormones and lowers blood pressure too, decreasing your chance of heart attack and stroke. In one 2012 study, researchers found an increase in oxytocin (also known as the "love hormone", which enhances my reward centres), when subjects listened to infant laughter.

I Get Better With Exercise

Exercise helps more than just keeping your bones strong and heart pumping. Art Kramer, from the University of Illinois, found that memory-one component of my many functions that declines with age-can improve with treadmill usage just three days a week, working up to an hour a day. Exercise increases blood flow to me, which delivers vital oxygen and glucose. MRIs revealed that areas pivotal for decision-making, planning, and multitasking also improved in those who went on the treadmill.

Watch Your Blood Pressure

There's a large body of research connecting high blood pressure and how I function. Hypertension (high blood pressure) puts a constant stress on me and your cardiovascular system, and it can physically be spotted on MRIs as white matter lesions. Don't ignore warning signs like having a "high-normal" reading, blood pressure creeping up slowly, or only getting high readings at the doctor's office.

Google Is Making Me Weak

A 2011 study from Columbia University found that you've been relying more on the Internet, less on me. That means I'm going to forget more over time. Study author Betsy Sparrow, PhD suggests we should focus on "greater understanding of ideas and ways of thinking," and less on memorisation.

Some Of Us Crave Junk Food

In one study, subjects were shown the names of foods they liked, and the parts of me that got excited were the same parts activated in drug addicts. This may have to do with dopamine, the hormone linked to motivation and pleasure, say researchers. The thinking goes that those with fewer dopamine receptors may need more food to make me happy

There's A Powerful Link Between Music, Nostalgia, And Me

In a 2010 study, researchers found just listening to a meaningful song from childhood brought on a happiness triggered by the fond memories.

I Can Predict Future Events

Findings from a 2012 study reveal exciting new evidence that my front-most region, the frontopolar cortex, helps predict future events from past experiences. It's not exactly psychic-superpowers, but I am able to make short-term predictions and think strategically about the future by drawing conclusions from recent patterns. For instance, the study's participants could anticipate slot machine payoffs based on previous trends in the games.

I Get Distracted Easily When We Go Shopping

Two cool new studies: One looked at the MRIs of participants watching deceptive ads (think: late-night infomercials). When I was cloudy from stress, lack of sleep, or low awareness, I was most likely to urge you to buy. Another study on shoppers noticed I may subconsciously push you to more expensive products if attractive, potential mates are nearby, so we impress them.

Sometimes, Even I Think You Should Trust Your Gut

One study showed students to be happier when they used me for simple decisions, and used their "gut" for more complex ones. In another study, participants let my unconscious state do the grunt work, and they showed less buyer's remorse. So, when you think hard on a big decision 'new job', don't get stuck on one of the factors (salary, long-term potential, location, et cetera) and instead, sleep on it.

Brain games might not do much for me

In a recent study, 11,430 volunteers aged 18 to 60 completed a series of online tasks for a minimum of 10 minutes a day, three times a week, for six weeks. Even though participants improved at the tasks, researchers believe that there wasn't a boost in general memory and learning abilities. Want to get sharp in your downtime? Listen to more music. Stanford University researchers found that it helps me better organise chaos, pay attention, make predictions, and update memory.

I Get Stimulated Easily, And Not By What You Might Expect

A 2011 study in Addiction Biology found that frequent tanning will fire off the same "reward" response for me as drug addiction "ie, I want to do it again and again." Ditto for binge eating, being popular on Facebook (!), or other obsessive activities. Find healthy ways to stimulate me: exercise, spending time with friends, treating yourself to a day of relaxation.

Ladies: I'm More Moody With You

Physically, I'm about ten per cent larger in men than women. It doesn't make guys smarter; it just lets me control their different bodies. Note that, neurologically, it's more common for women to suffer from mood disorders-but men are more likely to have ADHD or language disabilities.

I Peak In My 20s

Memory starts declining at around 27! Even though my ability to function doesn't start deteriorating until as early as 45, we will start losing some of my cells in your 20s. Beat the odds: Eat your way sharp with these seven research-backed foods like blueberries that help reduce the risk of Alzheimer's, and maintain your memory, and also boost my acetylcholine levels 'which helps improve memory function.'

Drinking Yourself Stupid? It's all myth

Alcohol disrupts brain function and hurts motor activity, like speaking or walking in a straight line. But it doesn't kill off entire cells; and adults who drink in moderation do not risk losing brain cells. As a bonus, a glass of red wine a night might protect me from stroke damage, according to a 2010 study.

You Can Train Me To Be Less Impulsive

In an isolated 2012 study, researchers found that people in a simulated gambling task could teach themselves to be more cautious bettors. With more research, scientists believe they can help with new developments in treating addiction and impulse-control disorders like ADHD.

Your MobilePhone Scares Me

New research from the National Institute of Health showed that less than an hour of mobile phone use can speed up my activity in the area closest to the phone antenna. Although the verdict isn't out yet on mobile phone usage and cancer, many more studies reveal mobile phone radiation could be linked with other disturbances, like sleep problems. Do us both a favour and limit use, or try a headset or earpiece.

Some Parts Of Me Never Sleep

It's important for you to get a good night's sleep, even if I'm busy: Sleep helps stabilises memories and it also may help me process them, by encoding the emotional bits and ditching the unnecessary details to remember the order of events.

I Can Be Reprogrammed To Be Happier

In one study, adults classified as pessimists showed higher death rates over a 30-year period than those who were optimists. To rewire me to become more optimistic, take positive actions! Recent research shows that genes play only a 30 to 40% role in your life outlook, and you can shift from being a pessimist to an optimist over time.

Meditation Is Groovy

A recent report found that those who meditated for about 30 minutes a day for eight weeks showed significant changes in my parts linked to memory, sense of self, empathy, and stress. Try silently repeating a calming word again and again to prevent distracting thoughts from inundating your brain, or focus on your breathing to be more in the moment.

I Can Trick You Into Thinking

But being swamped at the office or home isn't the kind of activity I need to stay healthy. People lose concentration by being immobile; exercise helps me rewire and shield against Alzheimer's disease, among many other health benefits. Help me by fitting in at least three to five sessions of cardio for 30 minutes a week. Can't swing that? Walk to work, park your car farther from the supermarket, take the stairs, or try dozens of other ways to get more movement in your day.

Eat omega-3s, Vitamin B, Complex Carbs, Antioxidants

Omega-3 fatty acids help my intellectual performance. Choline (the fat-like B vitamin in eggs and other foods) minimizes fatigue and increases my alertness without a trip to the closest Starbucks. It also helps with memory and stress resistance. Complex carbs are useful to improve my mental performance.

Prevent or better manage diabetes to keep me healthy

In June 2012, a nine-year longitudinal study showed that participants with diabetes who didn't control their blood sugar levels suffered from cognitive decline. Take control of your diabetes or prevent the disease completely by swapping everyday foods high in sugar for healthier choices, staying active with exercise, and seeing your doctor regularly.
