Artificially grown ‘mini-brains’ without animal components bring opportunities for neuroscience
Researchers at University of Michigan developed a method to produce artificially grown miniature brains — called human brain organoids — free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated. The work offers a solution to overcome Matrigel’s weaknesses.
The worm that learned: Diet found to affect learning in older nematodes
A group from Nagoya University in Japan has discovered that when the diet of nematodes, tiny worms measuring about a millimeter or less in length, includes the bacteria Lactobacillus reuteri, the weakening of associative learning ability caused by aging does not occur.
Brain imaging-based biomarker of depression identified
Researchers have recently begun making strides toward understanding the neurophysiology underlying different subtypes of depression, which could speed development of better treatments, but much remains to be discovered.
Study offers insights into neuroreceptor organization
A key challenge in neuroscience is to understand how the brain can adapt to a changing world, even with a relatively static anatomy.
Scientists discover spiral-shaped signals that organize brain activity
University of Sydney and Fudan University scientists have discovered human brain signals travelling across the outer layer of neural tissue that naturally arrange themselves to resemble swirling spirals.
Alcohol drinking cut in half with diabetes medication
Semaglutide is sold under brand names such as Ozempic. Since this medication was also approved for the treatment of obesity, demand has increased, which has resulted in difficulties in procuring the drug in recent times.
Deep-brain stimulation during sleep strengthens memory
This study provides provides the first physiological evidence from inside the human brain supporting the dominant scientific theory on how the brain consolidates memory during sleep. Further, deep-brain stimulation during a critical time in the sleep cycle appeared to improve memory consolidation.
Visual processing before moving hands: insights into our visual sensory system
Our hands do more than just hold objects. They also facilitate the processing of visual stimuli. When you move your hands, your brain first perceives and interprets sensory information, then it selects the appropriate motor plan before initiating and executing the desired movement.
Advanced brain imaging study hints at how DMT psychedelic alters perception of reality
In a study at Imperial College London, detailed brain imaging data from 20 healthy volunteers revealed how the potent psychedelic compound, DMT (dimethyltryptamine), alters brain function.
How brains synchronize during cooperative tasks
Humans are social creatures. But what leads to them being this way? To fully understand how the brain gives rise to social behaviors, we need to investigate it during social encounters.
Poor oral health may contribute to declines in brain health
Taking care of your teeth and gums may offer benefits beyond oral health such as improving brain health, according to preliminary research to be presented at the American Stroke Association’s International Stroke Conference 2023.
Why are human brains so powerful? University of Kentucky, Hebrew University partner to find out
Researchers at the University of Kentucky and Hebrew University in Jerusalem are partnering to study the complexity of the human brain. Specifically, researchers will test whether new, so-far unknown proteins exist in the brain.Labs from the two institutions have obtained a joint grant from the National Science Foundation (NSF) and the United States-Israel Binational Science Foundation (BSF) to study new aspects of RNA biology.
Traffic pollution impairs brain function
A new study by researchers at the University of British Columbia and the University of Victoria has shown that common levels of traffic pollution can impair human brain function in only a matter of hours.
Brain area necessary for fluid intelligence identified
A team led by UCL and UCLH researchers have mapped the parts of the brain that support our ability to solve problems without prior experience – otherwise known as fluid intelligence.
Multilevel brain atlases provide tools for better diagnosis
The multilevel Julich Brain Atlas developed by researchers in the Human Brain Project, could help in studying psychiatric and aging disorders by correlating brain networks with their underlying anatomical structure.
New view on the brain: It’s all in the connections
It’s not the individual brain regions but rather their connections that matter: neuroscientists propose a new model of how the brain works.
Identity theft the secret of the cat parasite’s success
The parasite Toxoplasma is carried by a large portion of the global human population.
Actors suppress their sense of self when playing a new character
Actors may suppress their core sense of self when acting, as they immerse themselves in a new role, finds a new study by UCL researchers.
Nightmares in middle age linked to dementia risk
People who experience frequent bad dreams in middle age are more likely to be diagnosed with dementia later in life, according to research at the University of Birmingham.
Mount Sinai Researchers Use Artificial Intelligence to Uncover the Cellular Origins of Alzheimer’s Disease and Other Cognitive Disorders
Deep learning models represent “an entirely new paradigm for studying dementia”
Biochemists Use Enzymes to Change How Brain Cells Communicate with Each Other
As you’re reading this sentence, the cells in your brain, called neurons, are sending rapid-fire electrical signals between each other, transmitting information.
Scientists of the Human Brain Project Shed New Light on Human Brain Organization
Specific cellular, molecular and gene expression patterns in brain areas are linked to function, but their precise relationships remain largely unknown.
Strange dreams might help your brain learn better, according to research by HBP scientists
The importance of sleep and dreams for learning and memory has long been recognized – the impact that a single restless night can have on our cognition is well known.
For Neurons, Where They Begin Isn’t Necessarily Where They End
Scientists at UC San Diego School of Medicine and Rady Children’s Institute of Genomic Medicine describe novel methods for inferring the movement of human brain cells during fetal development by studying healthy adult individuals who have recently passed away from natural causes.
