brain myths and stuff: don’t believe the hype.


Here is a reminder from your favorite neuroscience nerd ever (aka yours truly):
1. You’ve probably heard about that new movie “Lucy” about some lady who basically gets superpowers and gains the ability to use 100% of her brain when she could previously only use 10%. I know, I know, Morgan Freeman is in this movie and he’s the best, but don’t let it fool you. Despite what people say, you use much more than 10% of your brain. Your brain isn’t just some lumpy cognition machine; you need it for stuff you don’t even think about, like breathing, making your heart beat, regulating your body temperature, regulating your development, determining your skeletal muscle movements, et cetera. I could go on and on, but my point is that you kind of need all of it (read: 100%) to function optimally. The thing uses 20% of your energy alone. Give it some credit. 
2. I know you take that dumb right brain/left brain test because you KNOW you’re going to get “right brain-dominant” and feel like a creative special snowflake, but STOP. That test is garbage. You use your whole brain for stuff, okay? Lots of stuff goes on in both sides of your brain and, thanks to the corpus callosum, they work in tandem to make your life super easy. I could go into the whole “you need to study neurochemistry to fully understand the brain because neuroanatomy only tells you so much” talk, but that’s reserved for a different day. 
If you read all of this, you have way too much time on your hands, but thank you. Haha.

Scientists Closing in on Theory of Consciousness



Probably for as long as humans have been able to grasp the concept of consciousness, they have sought to understand the phenomenon.

Studying the mind was once the province of philosophers, some of whom still believe the subject is inherently unknowable. But neuroscientists are making strides in developing a true science of the self.

Here are some of the best contenders for a theory of consciousness.

Cogito ergo sum

Not an easy concept to define, consciousness has been described as the state of being awake and aware of what is happening around you, and of having a sense of self. [Top 10 Mysteries of the Mind]

The 17th century French philosopher René Descartes proposed the notion of “cogito ergo sum” (“I think, therefore I am”), the idea that the mere act of thinking about one’s existence proves there is someone there to do the thinking.

Descartes also believed the mind was separate from the material body — a concept known as mind-body duality — and that these realms interact in the brain’s pineal gland. Scientists now reject the latter idea, but some thinkers still support the notion that the mind is somehow removed from the physical world.

But while philosophical approaches can be useful, they do not constitute testable theories of consciousness, scientists say.

"The only thing you know is, ‘I am conscious.’ Any theory has to start with that," said Christof Koch, a neuroscientist and the chief scientific officer at the Allen Institute for Neuroscience in Seattle.
