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. |

I believe that the brain has evolved over millions of years to be responsive to different kinds of content in the world. Language content, musical content, spatial content, numerical content, etc. |

When you rise in the morning, give thanks for the light, for your life, for your strength. Give thanks for your food and for the joy of living. If you see no reason to give thanks, the fault lies in yourself. |

I don't really watch what I eat. I love sitting around with friends and eating loads and drinking loads for hours. Maybe when I'm 40 I'll worry about my diet. |

The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building. |

Scar tissue is stronger than regular tissue. Realize the strength, move on. |

He who has seen one cathedral ten times has seen something; he who has seen ten cathedrals once has seen but little; and he who has spent half an hour in each of a hundred cathedrals has seen nothing at all. |

I'd always avoided stuff like 'Where are they now?' or 'Whatever happened to?' Just 'No thanks, thanks for calling.' You tell me, have you ever seen a 'Whatever happened to' where they seemed anything but pathetic? |

I went through this phase where I thought pink and purple matched. To dance class, I'd wear purple tights and pink leg warmers and paint my shoes purple. It was really odd. |

On the musical side, I always wanted to kind of carry on Pink Floyd's sound. You know, Pink Floyd always had such an original, creative and masterful sound, but there are no new albums. My thought was that there's a way to keep their sound alive. |

I wore a pink Betsey Johnson dress to my prom, and I pretty much looked like a pink cupcake. I loved that dress! |

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.

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...

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.

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...

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.

In the 1990s, a British scientist, Jennifer Luke, discovered that fluoride accumulates to strikingly high levels in the pineal gland. (Luke 2001). The pineal gland is located between the two hemispheres of the brain and is responsible for the synthesis and secretion of the hormone melatonin. Melatonin maintains the body?s circadian rhythm (sleep-wake cycle), regulates the onset of puberty in females, and helps protect the body from cell damage caused by free radicals.
While it is not yet known if fluoride accumulation affects pineal gland function, preliminary animal experiments found that fluoride reduced melatonin levels and shortened the time to puberty. (Luke, 1997). Based on this and other evidence, the National Research Council has stated that ?fluoride is likely to cause decreased...

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.

Researchers have developed a technique that allows them to rapidly thaw cryopreserved human and pig samples without damaging the tissue -- a development that could help get rid of organ transplant waiting lists. Cryopreservation is the ability to preserve tissues at liquid nitrogen temperatures for long periods of time and bring them back without damage, and it's something scientists have been dreaming about achieving with large tissue samples and organs for decades. Instead of using convection, the team used nanoparticles to heat tissues at the same rate all at once, which means ice crystals can't form, so they don't get damaged. To do this, the researchers mixed silica-coated iron oxide nanoparticles into a solution and generated uniform heat by applying an external magnetic field. They then warmed up several human and pig tissue samples ranging between 1 and 50 mL, using either their new nanowarming technique and traditional slow warming over ice. Each time, the tissues warmed up w...

Enormous water worlds appear to be common throughout the Milky Way. The planets, which are up to 50% water by mass and 2-3 times the size of Earth, account for nearly one-third of known exoplanets.
