Astrocytes: these cells could be part of the key to unlocking the mystery of how brains change their structure.
From the archive: new research helps unpick clues about the brain’s ability to change its structure. Listen to The Conversation Weekly podcast.
Swimming offers a host of beneficial effects on the brain.

Nicola Sturgeon wants to use a mandate at the May 6 elections to argue for a second independence referendum.
Plus, how researchers have discovered a biological switch that can turn neuroplasticity on and off in the brain. Listen to episode 13 of The Conversation Weekly podcast.

Adaptable neurons are tied to learning and memory but also to neurological disorders. By studying fruit flies, researchers found a mechanism that controls neuroplasticity.
Our brains communicate information in a manner that can be likened to an air traffic controller.
Air traffic controllers have to process and manage large amounts of information to get airplanes to their destinations. The brain manages the incessant traffic of neurons in a similar fashion.
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.
As people age, their sense of smell can decline.
Our ability to smell is a function of the brain, so it makes sense that an impaired sense of smell can point to cognitive decline. The good news is training our noses may be effective.
Microdosers take such small quantities of psychedelic substances that there are no noticeable effects.
Popular accounts of the effects of microdosing don’t quite match the experience of long-term microdosers, according to this new research.
Many board games strengthen the hippocampus and prefrontal cortex of the brains of players. This results in improved cognitive functions such as IQ, memory, information retention and problem-solving.
From dyslexia, to dementia to schizophrenia, there is evidence that playing games can help, while boosting family connections and emotional wellbeing.
Could it be that a baby has all the brain cells she ever will?

Neuroscience labs around the world may need to reevaluate some of their assumptions about whether what works in animals will really produce meaningful treatments for people.
Biomedical engineering involves the application of engineering solutions to medical problems. Employment in the field is projected to grow 23 per cent from 2014 to 2024.
One professor explains how war in Iran led her to a career in biomedical engineering - a rapidly growing field that offers students exciting opportunities to serve humanity.
Brain training programs support healthy brain ageing – but you’ve got to choose the right one.
Many brain training programs are based on the principles of neuroplasticity. But a new study shows that less than 40% are backed by proof of efficacy.
We don’t need fancy gadgets to improve our brain power.
When research and commerce become entangled, consumers are the losers.
The malleable brain.
Without the ability to rewire itself, the brain wouldn’t be able to grow or recover from injury.
Where did I leave my skull cap?
Research into how feelings and opinions can be shaped using technology or drugs could impact the whole of society not just the individuals concerned.
Your pain is in fact produced in your head and it will produce it more readily and more intensely if you have what you think is clear evidence that something is wrong.
People develop a long-term problem after an episode of back pain if they expect to not recover. Steps by the medical sector to avoid catatrophising back pain by not suggesting scans will help.
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 today in the journal Current Biology. “The take-home message the study authors…
It’s not all bad news for older brains.

For years, conventional wisdom held that growing older tends to be bad news for brains. Past behavioral data largely pointed to loss in cognitive – that is, thinking – abilities with age, including poorer…
Childhood memories seem few and far between – if they still exist at all. So why can’t we dig them up as adults?
Memories from early childhood are notoriously elusive but why can’t we recall our most formative experiences? New research suggests it could be a case of the old making way for the new – neurons, that…
