Brain defects go a long way
|
view preview
This is a human brain without grooves and folds, a condition known as lissencephaly. It belonged to a patient who died in a mental health facility in 1970, and almost a year ago a photographer found the jar containing the brain in a collection at the University of Texas, Austin. People with this rare condition suffer from seizures, muscle spasms, a range of learning difficulties, and usually die before the age of ten. ...

Left-brain versus right-brain?
|
view preview
We've all heard about the right brain-left brain theory, which we owe to Nobel Prize winner Roger W. Sperry. The theory suggests that ‘left-brained’ people are more logical and analytic than ‘right-brained’ people, who are more creative and have a holistic approach to life, but is it true? Despite its popularity, researchers say that most people learn to be both logical and creative and that lateralised patterns of brain activity change as we age. ...

Sleep-deprived? You want to read this
|
view preview
Researchers have found that chronic sleep loss is more serious than previously thought and may lead not only to loss of brain cells, but to irreversible physical damage. According to this study, people who don’t sleep enough can also be at risk of neurodegenerative disorders such as Alzheimer’s and Parkinson’s.

A new brain study suggests that autism starts before birth
|
view preview
Autism may start during the second and third trimesters of pregnancy, a new study showed. The researchers found patches of altered brain cells in the frontal and temporal cortexes of children with autism, important brain areas for social interaction and language. Although the scientists still have to figure out what causes these patches of brain cells, genetic factors and conditions inside the womb could be the culprits.

Trippy mushrooms
|
view preview
Users of magic mushrooms often report altered states of consciousness and a synesthesia-like melding of the senses. Now, scientists may have figured out why: Psilocybin changes the brain’s wiring, creating a hyperconnected brain that contains links between regions that don’t normally communicate with each other. Communication between brain networks in people given psilocybin (right) or a non-psychedelic compound (left). ...

Want to become a brain surgeon? Better get used to this
|
view preview
Watch as a neurosurgeon opens up a patient's skull and clears the clotted blood from the surface of her brain. We probably don't have to tell you that this is extremely graphic footage, but - you've been warned.

Good bacteria helps to defend your brain
|
view preview
The microbes that live in your body outnumber your cells 10 to one. Recent studies suggest these tiny organisms help us digest food and maintain our immune system. Now, researchers have discovered yet another way microbes keep us healthy: They are needed for closing the blood-brain barrier, a molecular fence that shuts out pathogens and molecules that could harm the brain.
