Types of input the brain interprets include odors, light, sounds, and pain. The brain also helps perform vital operations such as breathing, maintaining blood pressure, and releasing hormones (chemical signals that control certain cells and organs).

Improving Memory

They make up our internal biographies—the stories we tell ourselves about what we've done with our lives. They tell us who we're connected to, who we've touched during our lives, and who has touched us. In short, our memories are crucial to the essence of who we are as human beings. That means age-related memory loss can represent a loss of self. It also affects the practical side of life, like getting around the neighborhood or remembering how to contact a loved one.

Athletes are better at tuning out background brain noise. People who play sports appear to have an enhanced ability to process sounds from their environment, according to new research.

Athletes are better at tuning out background brain noise

Share on Pinterest Scientists at Northwestern University in Evanston, IL, measured brain activity relating to sound processing in athletes and nonathletes. They found that due to a stronger ability to lessen the background electrical noise in their brains, the athletes were better at processing signals from external sounds. The team reports the findings in a recent paper in the journal Sports Health: A Multidisciplinary Approach. "No one would argue against the fact that sports lead to better physical fitness, but we don't always think of brain fitness and sports," says senior study author Nina Kraus, a professor of communication sciences and neurobiology at Northwestern University and director of its Auditory Neuroscience Laboratory.

"We're saying," she continues, "that playing sports can tune the brain to better understand one's sensory environment. " What Makes Our Brains Special? The human brain is unique: Our remarkable cognitive capacity has allowed us to invent the wheel, build the pyramids and land on the moon.

What Makes Our Brains Special?

In fact, scientists sometimes refer to the human brain as the “crowning achievement of evolution.” But what, exactly, makes our brains so special? Some leading arguments have been that our brains have more neurons and expend more energy than would be expected for our size, and that our cerebral cortex, which is responsible for higher cognition, is disproportionately large—accounting for over 80 percent of our total brain mass. Suzana Herculano-Houzel, a neuroscientist at the Institute of Biomedical Science in Rio de Janeiro, debunked these well-established beliefs in recent years when she discovered a novel way of counting neurons—dissolving brains into a homogenous mixture, or “brain soup.” Brain Myth - Human Brain is Biggest. While scientists can't agree on a single definition of “intelligence,” they generally concur that humans are the most intelligent living creature on Earth.

Brain Myth - Human Brain is Biggest

Because of this belief, some people assume that human beings also have the biggest brains – they assume that the bigger the brain, the smarter the animal. But that is not exactly true. The average adult human brain weighs about 3 pounds – the same weight as the average brain of a dolphin (which is also a very intelligent animal). But there are animals with larger brains that are not considered to be as intelligent as a dolphin.

For instance, a sperm whale has a brain that weighs about 17 pounds. On the other hand, some relatively “smart” animals have small brains – for example, dogs and orangutans: A beagle's brain is about 2.5 ounces, and an orangutan's brain is about 13 ounces. Animal brains v human brains – let the Battle of the Brains commence! Humans are widely assumed to be the most intelligent species on Earth due to our intricate civilisations and innovative behaviours.

Animal brains v human brains – let the Battle of the Brains commence!

But, have you ever considered that our brains have features that are inferior to animal brains? We’ve pitted humans against the rest of the animal kingdom in various categories to reveal whose has the best cerebellum, the brightest cerebrum, and the greatest grey matter in the ultimate Battle of the Brains. Smell Unsurprisingly, humans won’t receive any awards for our sense of smell. While our brains are relatively large compared to most other animals, the part of our brains devoted to smell, the olfactory bulb, is comparatively small. However, the exceptional sense of smell many species possess is not only due to differences in brain anatomy, but also a result of adaptations to their noses.
