A new study raises hopes of better treatment for amnesia, Alzheimer's and other conditions affecting memory.
How we experience the moment of death may be influenced by a cocktail of brain chemicals and the manner in which our brains shut down.

We have a strong tendency to overreact emotionally and underreact behaviourally to news of infectious diseases.
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) is a research facility designed to simulate conditions on Mars.
In preparation for possible future missions to Mars, scientists figure out how to quickly and efficiently measure brain performance and mental fatigue.
Just a few millimeters across, organoids are clumps of cells that resemble the brain.

Brain organoids are tiny models that neuroscientists use to learn more about how the brain grows and works. But new research finds important differences between the model and the real thing.
Our mental health benefits when nature is part of our neighbourhoods, as in this residential street in Fitzroy, Melbourne.
It's well-established that green spaces are good for our well-being. Now we can demonstrate that greater biodiversity boosts this benefit, as well as helping to sustain native plants and animals.
Alcohol interferes with the consolidation and retrieval of memories, leading to confusion and uncertainty the next day.
Post-party 'hangxiety' is common after drinking alcohol. It is caused by changing levels of chemicals and neurotransmitters in the brain.
New research could help you win an argument.
Were you subtly encouraged to make that menu choice?
A scholar who studies consumer decision-making explains just what it is in the human mind that makes people susceptible to nudges toward one behavior or another.
The teenage brain has a voracious drive for reward, diminished behavioural control and a susceptibility to be shaped by experience. This often manifests as a reduced ability to resist high-calorie junk foods.
Excessively eating junk foods during adolescence could alter brain development, leading to lasting poor diet habits. But, like a muscle, the brain can be exercised to improve willpower.
Neurostimulation is rife with potential and pitfalls.
From dementia to depression to drug addiction, artificial brain stimulation has been hailed as a landmark medical technology for the future. But safeguards are needed if we want the benefits without the risks.
It’s these brain cells that really make humans unique.
We have more neurons in our cortices than any other species, courtesy of an early technology – and along with them came our long, slow lives, with plenty of chances to gather around the dinner table.
Those smiles probably aren’t thanks to tryptophan.

Tryptophan, found in food, is an important ingredient in the neurotransmitter serotonin. But is that enough to support it as a possible mood booster? The research is decidedly mixed.
When you’re looking for a destination, you might need to cut down the volume.
Do you ever find you suddenly need to turn off the radio so you can concentrate on what you're doing? It's because you only have a finite amount of attention, for particular types of tasks at least.
Fake news works at a cognitive level to shape our perceptions and drive our decisions.
We fall sway to fake news because it grabs our attention through outlandish claims, suggests false memories and contains appeals to our emotions that align with our politics.
The average Canadian adult consumes more than triple the daily limit of 25g added sugar recommended by the World Health Organization.
Sugar triggers dopamine "hits" in the brain, making us crave more of it. Sugar also disrupts memory formation.
We knew people with Parkinson’s disease were at heightened risk of developing addictive behaviours like gambling. Our research gives insight into why this is.
About one in six people who take the most common medication for Parkinson's disease will develop addictive behaviours. We found whether this happens depends on a person's unique brain structure.
The frequency and intensity of repetitive behaviours vary between mild and severe, which is why it’s called a spectrum.
It's been 25 years since autism was redefined and the surge in diagnoses and research began. But while we've come along way in our understanding of the spectrum, advances in drug therapies has lagged.
Different MR images help us unravel the mysteries of the brain. A diffusion MRI tractography reconstruction like this reveals the complicated wiring deep within a person’s brain.
Odd findings in a brain scan of a 29-year-old woman have scientists asking new questions about how our sense of smell really works.

One day we will have a science of consciousness, but it won’t be science as we know it today
