Detecting dementia’s damaging effects before it’s too late

Scientists might have found an early detection method for some forms of dementia, according to new research by the University of Arizona and the University of Toronto’s Baycrest Health Sciences Centre. According to the study published in the journal Neuropsychologia last month, patients with a rare neurodegenerative brain disorder called Primary Progressive Aphasia, or PPA,

Why creative experts may be better at imagining the future

Humans use imagination a lot, whether it be thinking about what’s for dinner later tonight or trying to imagine what someone else on the other side of the world may be experiencing after reading the news. As situations become farther away from reality and more distal, imagining a situation becomes more difficult. The limits to

Connecting neurons in the brain

The brain consists of a large collection of interconnected neurons. How complex patterns of neuronal cells grow into functioning circuits during development has fascinated researchers for decades. A team of scientists at VIB and KU Leuven has now uncovered a new signaling mechanism in fruit flies that specifies the formation of neuronal circuits in the

Early lipids boost brain growth for vulnerable micro-preemies

Dietary lipids, already an important source of energy for tiny preemies, also provide a much-needed brain boost by significantly increasing global brain volume as well as increasing volume in regions involved in motor activities and memory, according to research presented during the Pediatric Academic Societies 2019 Annual Meeting. “Compared with macronutrients like carbohydrates and proteins,

Study shows promise in repairing damaged myelin: Potential ‘game-changer’ for people with multiple sclerosis

A scientific breakthrough provides new hope for millions of people living with multiple sclerosis. Researchers at Oregon Health & Science University have developed a compound that stimulates repair of the protective sheath that covers nerve cells in the brain and spinal cord. The discovery, involving mice genetically engineered to mimic multiple sclerosis, published in the

Blue Brain solves a century-old neuroscience problem

A team led by Lida Kanari now reports a new system for distinguishing cell types in the brain, an algorithmic classification method that the researchers say will benefit the entire field of neuroscience. Blue Brain founder Professor Henry Markram says, “For nearly 100 years, scientists have been trying to name cells. They have been describing

Scientists hunt down the brain circuit responsible for alcohol cravings: Study may open the door to developing drug therapies or even gene therapies for alcohol addiction

Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats — with the flip of a switch. The researchers were able to use lasers to temporarily inactivate a specific neuronal population, reversing alcohol-seeking behavior and even reducing the physical symptoms of withdrawal. “This discovery is exciting — it

EEG helps scientists predict epileptic seizures minutes in advance: Prevention: Edible acid can stabilize misfiring neurons

Elizabeth Delacruz can’t crawl or toddle around like most youngsters nearing their second birthday. A rare metabolic disorder that decimated her mobility has also led to cortical blindness — her brain is unable to process images received from an otherwise healthy set of brown eyes. And multiple times a day Elizabeth suffers seizures that continually

Brain condition related to long-term spaceflights needs more attention, data: Researchers sound alarm as humans prepare for extended time in space

More people today are poised to explore space than ever before; those who do will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, M.D., and co-author Lonnie G. Petersen, M.D.,Ph.D., University of California San Diego,

A muscle protein promotes nerve healing

Typically, damaged nerve fibres of the central nervous system (CNS) in the brain, the optic nerve and spinal cord don’t have the ability to regenerate. One of the pivotal reasons is that nerve fibres don’t produce any proteins that are necessary for their regeneration, or that they don’t produce enough of those proteins. The team

Different brain areas linked to smoking and drinking

Academics at the University of Warwick have found that low functional connectivity of the lateral orbitofrontal cortex that is associated with the tendency to smoke is associated with increased impulsiveness — which may contribute to the tendency to smoke. The high connectivity of the reward-related medial orbitofrontal cortex in drinkers may increase the tendency to

To predict the future, the brain uses two clocks: In music, sports and other activities, we calculate movement in two different parts of the brain

That moment when you step on the gas pedal a split second before the light changes, or when you tap your toes even before the first piano note of Camila Cabello’s “Havana” is struck. That’s anticipatory timing. One type relies on memories from past experiences. The other on rhythm. Both are critical to our ability
