The fashion advice is generally to tighten ties so they’re tight but not too tight.
Wearing a tie that causes slight discomfort can reduce blood flow to the brain by 7.5%, but the reduction is unlikely to cause any physical symptoms, which generally begin at a reduction of 10%.
Lifestyle factors such as meditation can change our brain for the better.
How can exercise, meditation and hypnosis change our brains and potentially prevent disease?
Statistics has Guinness to thank for the Student’s t-test.
A statistical method widely used today by scientists and others is all thanks to a statistician at a Guinness brewery whose work was published anonymously more than a century ago.
A hallmark of Alzheimer’s disease is gradual deterioration of memory.
Alzheimer's disease is the most common form of dementia, but treatments are still far from successful in clinical trials. Here is what we know about the disease, and what is yet to be uncovered.
Why do we retain some memories better than others?

The Florey Institute's Dr Jee Hyun Kim explains how the different aspects of memory work and why attention is the most important element of improving your memory in this long-form comic explainer.
The pathway from eye to brain begins in the retina, where light is converted into neuronal signals.
Light arriving from the right visual field is processed in the brain's left hemisphere. So damage to the left part of the primary visual cortex will result in blindness in the right visual field.
Our mood is a transient frame of mind that influences how we think and view the world.
Many regions fundamental to mood are buried deep in the most primordial parts of the brain; that is, they are thought to have been among the first brain regions to develop in the human species.
Our language abilities are enabled by a co-ordinated network of brain regions that have evolved to give humans a sophisticated ability to communicate.
When you read this text, certain regions in your brain begin working more than others. Advanced imaging allows scientists to map the brain networks responsible for understanding language.
Success in human drug development is painfully low.
News reports this week hailing a breakthrough in Alzheimer's research, saying a vaccine for the disease is a few years away, have raised hopes for many. But let's take a step back from the headlines.
Motor symptoms of Parkinson’s include tremors, stiffness and slowness or loss of spontaneous movement.
Parkinson’s disease is the second-most-prevalent neurodegenerative condition in Australia, with an estimated 70,000 living with the disease. But what do we know about the causes and risk factors?
The health sector can learn from other industries that turn to operations research to fix everyday challenges.
Fixing the hospital system is not just a matter of more funding. Hospitals need to work smarter, not harder.
The brain implant sends signals to anything from a bionic prosthetic limb, to a full body ‘exoskeleton’
A 3cm-long stent containing 12 electrodes could one day help people living with spinal cord injury to walk with the power of thought.

When asked about importing cannabis oil to treat child epilepsy, rural health minister Fiona Nash told Q&A that the TGA can allow importation of products not registered in Australia. Is that right?
Epilepsy is one of the most common neurological conditions in the world.
Saying someone has epilepsy is a little like saying they're ill. Its cause can vary from a brain tumour to an inherited genetic condition, the consequence of injury or a disorder affecting the brain.
Prion diseases are a rare class of brain disorders that are transmissible between animals of any species, including humans.
New research has identified a known neurodegenerative disease as being caused by prions. And it has again raised the possibility that these proteins are infectious.
Epigenetic molecules play a different melody on different people’s genomes, and this might be contributing to some developing autism.
The epigenetic 'musicians' that play our genomes in different ways might help us understand the causes of autism.
The human brain leaves computers behind with its endless capacity for problem solving, innovation and invention.

People who stay mentally stimulated and physically active can delay onset of cognitive decline.
Older people may be able to learn more from visual information than their younger counterparts, according to a study published…
The amount of sun exposure and associated vitamin D production is believed to underlie the geographical gradient in multiple sclerosis prevalance.
Multiple sclerosis is a neurological disease affecting almost 25,000 Australians and more than 2.4 million people worldwide. It’s one of the leading causes of disability in young adults. Typically, the…
