A common symptom of not getting enough quality sleep is ‘brain fog’ — when thoughts aren’t as clear and focused as they should be.
We live in a world where we frequently do not get enough sleep, but we need sleep if our brains are going to stay healthy and function efficiently.
The way human brains develop is special – but not quite as special as you’d like to think, if we consider Neanderthals as well.
Asymptomatic sensitization may lead people to continue consuming food allergens, causing hidden neurological issues.

Food allergies have been linked to behavioral and mood disorders, including depression, anxiety and ADHD.
As the planet heats up, air pollution is getting worse.
In a systematic review of existing studies, researchers found that air pollution such as fine particulate matter can interfere with regions of the brain responsible for emotional regulation.
Sleep plays a critically important role in the recovery process in the days following a concussion.

While high-profile concussions in the NFL have brought renewed attention to the gravity of head injuries, they can also occur on the playground or during junior varsity practices – with lasting effects.
The U.S. BRAIN Initiative seeks to elucidate the connection between brain structure and function.

From figuring out where memories are stored to how sensory information translates to behavior, new technologies are helping neuroscientists better understand how the brain works.
Approximately 10% of people will experience at least one seizure during their lifetime.

Because some seizures are relatively subtle, they can go unrecognized, leading to a delay in diagnosis.

Long overlooked by scientists, white matter may provide clues to some of the brain’s greatest mysteries.
The technology is progressing but it must pass a number of regulatory hurdles. We’re unlikely to see an affordable implant in the short term.
Aphasia is a language disorder that affects about 30 per cent of stroke patients.
Across Canada and the United States, more than two million people are living with aphasia and its language and communication challenges.
People can have several thousand thoughts per day, many of which can be classified as spontaneous or involuntary.
Emotions play a key role in many types of spontaneous thoughts. Even microemotions — which are often fleeting and unconscious — can affect thoughts and influence attention.
Typically, people who experience psychosis encounter it in young adulthood or alongside dementia later in life. Post-COVID psychosis can hit adults in their middle years.
A look at how we decide which experts are the most trustworthy - and the possible biological basis behind it.
A new brain-imaging study finds that participants who had even mild COVID-19 showed an average reduction in whole brain sizes.

New research offers insights into the brain after COVID-19 that may have implications for our understanding of long COVID-19 and how the disease affects our senses of taste and smell.
Drinking more water can make you feel happier – and not drinking enough may contribute to feelings of anxiety and fatigue.

Insects such as ants and beetles use ingenious processes in their brains to work out how far they’ve travelled and in what direction - we’ve now discovered how they remember their way home.
Without a diagnosis, girls might experience social difficulties and traumatic situations – and grow into women who blame themselves.
An estimated 69 million people worldwide experience a traumatic brain injury every year.

The molecule C1q has both protective and detrimental effects after traumatic brain injury. Blocking it after injury in mice restored normal brain rhythms during sleep and prevented epileptic spikes.
Conversation in person usually feels effortless. Conversation over video? Not so much.

It appears that the rhythms of your brain waves get in sync with the speech patterns of the person you’re conversing with. Videoconferencing throws off that syncing process.
