Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function. |

We have to remain humble about our understanding of the brain, because even our most powerful tools remain pretty blunt instruments for decoding the brain. In fact, we still do not know how to decipher the basic language of how the brain works. |

There is no such thing as a disembodied mind. The mind is implanted in the brain, and the brain is implanted in the body. |

A man's brain has a more difficult time shifting from thinking to feeling than a women's brain does. |

Your brain develops depending on your individual history. What has gone on in your own brain and its consciousness over your lifetime is not repeatable, ever - not with identical twins, not even with conjoined twins. |
| Gerald Edelman |
Each brain is exposed to different circumstances. It's very likely that your brain is unique in the history of the universe. |

Many cognitive psychologists see the brain as a computer. But every single brain is absolutely individual, both in its development and in the way it encounters the world. |

The hardest thing in golf is trying to two-putt when you have to, because your brain isn't wired that way. You're accustomed to trying to make putts, and when you change that mind-set, your brain short-circuits, especially under pressure. |

The brain's calculations do not require our conscious effort, only our attention and our openness to let the information through. Although the brain absorbs universes of information, little is admitted into normal consciousness. |

Neuroscientists talk a lot about brain circuits. In fact, the word 'circuit' is probably misleading. We do not know where most circuits begin and end. And unlike an electrical circuit, brain connections are heavily reciprocal and recursive, so that a direction of information flow can be inferred but sometimes not proven. |

80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue.

Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.

Counter-intuitively, Koubeissi’s team found that the woman’s loss of consciousness was associated with increased synchrony of electrical activity, or brainwaves, in the frontal and parietal regions of the brain that participate in conscious awareness. Although different areas of the brain are thought to synchronise activity to bind different aspects of an experience together, too much synchronisation seems to be bad. The brain can’t distinguish one aspect from another, stopping a cohesive experience emerging.

Open Mike Eagle's brain was studied using an fMRI to determine the differences of how your brain reacts while freestyling, compared to a rehearsed performance.

The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain.

As the brain is a composite material, made up of grey matter, white matter and fluids, the researchers use data from medical imaging, such as MRI to decompose the brain into subvolumes, similar to lego blocks. The color of each lego block depends on which material it represents: white, grey or fluid. This colour-coded "digital lego brain" consists of thousands of these interacting and deforming blocks which are used to compute the deformation of the organ under the action of the surgeon.

t is well known that a high salt diet leads to high blood pressure, a risk factor for an array of health problems, including heart disease and stroke. But over the last decade, studies across human populations have reported the association between salt intake and stroke irrespective of high blood pressure and risk of heart disease, suggesting a missing link between salt intake and brain health.
Interestingly, there is a growing body of work showing that there is communication between the gut and brain, now commonly dubbed the gut–brain axis. The disruption of the gut–brain axis contributes to a diverse range of diseases, including Parkinson’s disease and irritable bowel syndrome. Consequently, the developing field of gut–brain axis research is rapidly growing and evolving. Five years ago...

Consciousness is generally thought of as being comprised of two critical components - arousal and awareness.
Researchers had already shown that arousal is likely regulated by the brainstem - the portion of the brain that links up with the spinal cord - seeing as it regulates when we sleep and wake, and our heart rate and breathing.
Awareness has been more elusive. Researchers have long thought that it resides somewhere in the cortex - the outer layer of the brain - but no one has been able to pinpoint where.

Tantalizing But Preliminary Evidence of a 'Brain Microbiome'
An anonymous reader quotes a report from Science Magazine:
We know the menagerie of microbes in the gut has powerful effects on our health. Could some of these same bacteria be making a home in our brains? A poster presented here this week at the annual meeting of the Society for Neuroscience drew attention with high-resolution microscope images of bacteria apparently penetrating and inhabiting the cells of healthy human brains. The work is preliminary, and its authors are careful to note that their tissue samples, collected from cadavers, could have been contaminated. But to many passersby in the exhibit hall, the possibility t...

It's no secret that Big Sherm smoke mad ganj. Lately been smoking about a half ounce a week. Sometimes when I am on a long run of being high from waking up to going to bed, I get lost in my head (lol wonder why) and I think that this is just how my brain and thoughts works now. But every time I take a break even for just a day or two, my head clears back up and thoughts flow naturally again. The point of me posting this is that weed is awesome. Everything in moderation (something I clearly have trouble with in all aspects of my life) but this really proves to me that ganj is great cuz I can just stop and be normal again. When I'm on a long kick of smoking I analyze how my brain is functioning and while it does have longterm effects, it really is crazy how I can get right back into things with just a few days of detox. I have quit drinking for the most part, next is cigarettes and weed.
