Regardless of disease severity, people who have lingering smell loss after covid-19 are more likely to have cognitive problems than those who regain or never lose their sense of smell  

This is in line with a recent theory on how our brain works: it is a prediction machine, which continuously compares sensory information that we pick up (such as images, sounds and language) with internal predictions.

An analysis of fossils suggests changes in the shape of the braincase during human evolution were linked to alterations in the face, rather than changes in the brain itself

Do you ever listen to music before bed? That might be helping to keep you well rested.

College coeds who play action video games make faster, better decisions than non-gamers, a study shows.

People who eat the highest amounts of ultra-processed foods like soft drinks, chips and cookies may have a higher risk of developing dementia than those who eat the lowest amounts, according to a new study published in the July 27, 2022, online issue of Neurology®,

The ability of aromas to bring back highly specific memories is becoming better understood, and could be used to boost and heal our brains.

A new study has identified that variation in genes coding for key receptors in our brains may alter the potency of psychedelic drugs. The research suggests that our genetics should be a factor in future clinical trials of these drugs’ therapeutic potential.

Movement is much more complicated than you might think. Any one activity, whether it's opening your mouth to speak or running a marathon, involves complicated interactions in our brains. This complexity means that there’s still much about movement that scientists struggle to understand.

Improved understanding of a neural pathway connecting light-sensitive cells in the retina with the cortical brain regions involved in mood and cognition has implications for the development of treatments for mood disorders.

Last month, drug company Genentech reported on the first clinical trials of the drug crenezumab, a drug targeting amyloid proteins that form sticky plaques in the brains of Alzheimer’s disease patients. The drug had been particularly effective in animal models, and the trial results were eagerly awaited as one of the most promising treatments in years. It did not work.

For three decades, people have been deluged with information suggesting that depression is caused by a “chemical imbalance” in the brain – namely an imbalance of a brain chemical called serotonin. However, our latest research review shows that the evidence does not support it.

The benefits of animal therapy for memory and mental health are well documented. Some agencies are using realistic robotic pets as a therapeutic tool for memory care in older adults. Now, researchers have developed a new protocol for the use of robotic animals to aid in memory care.

There may be no link between serotonin levels and depression, according to an analysis of 17 studies. This raises questions about antidepressants that focus on this brain-signalling molecule, say the authors of the analysis. Not everyone is convinced by the findings, though.

Stories stimulate the brain in the same way, regardless of whether they're read or heard.

Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are the two most prominent psychoactive substances found in the cannabis plant. According to data from two placebo-controlled, double-blind studies, CBD appears to buffer against some of the acute effects of THC on the brain. The new findings, which appear in the Journal of Psychopharmacology, suggest that cannabis strains with greater CBD content may be less harmful.

The study used a brainwave signal called P300 to control information metasurface, which can code 0s and 1s like an electronic circuit board.

Psychedelic substances may take us places that standard treatment hasn’t yet.

The latest findings add to the understanding of how social disadvantage such as poverty and low-quality, unsafe housing can affect early child development.

Male mice, even those that are young and sexually naïve, are hard-wired to quickly discern the sex of another mouse. What’s more,researchers have for the first time identified the neurons in the male mouse brain that guide the behavior.
