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.

Despite its huge complexity, your brain directs its neural traffic in relatively straightforward ways when approaching cognitively demanding tasks such as puzzles.
Suicide is a growing health problem.

Suicide is the second leading cause of death for teens in America. But there may be ways to study the stress response and figure out who is most at risk.
What makes a brain tick is very different from how computers operate.

Brain functions integrate and compress multiple components of an experience, including sight and smell – which simply can’t be handled in the way computers sense, process and store data.
Red quantum dots glow inside a rat brain cell.
Nanoscale Advances, 2019, 1, 3424 - 3442
These tiny nanoparticles might provide a new way to see what’s happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.
Honeybees are good at maths, but it was thought they could only count to four. That is, unless you present them with a task in which they are punished with a bitter-tasting drink for getting it wrong.
Same sex sexual behavior is common to many species and evolved millions of years ago.

Conversion therapy has been pushed on some in the LGBQ community by those who think same-sex sexual behavior is ‘unnatural.’ But such behavior seems to have evolved millions of years before humans.
The human brain has an estimated 100 billion neurons and 100 trillion neural connections.

Sections in the brain called “senders” and “receivers” are responsible for directing neural traffic, and we are now a step closer to understanding how they work.
Like a cocktail partygoer able to focus on one discussion in a noisy room, brains are able to make reliable connections against a busy neural background. Here are two phenomena that help it happen.
