Health Imaging: Brain fMRI finds people with schizophrenia less reactive to positive social experiences

UCLA researchers have found that the brains of people with schizophrenia are less reactive to social rewards such as positive interactions with others and smiling, according to research published Sept. 5 in Schizophrenia Bulletin. The findings demonstrate how people with schizophrenia are more likely to find social stimulation unrewarding and contribute to problems with socializing, […]

NPR: Scientists study barn owls to understand why people with ADHD struggle to focus

Kids with ADHD are easily distracted. Barn owls are not. So a team at Johns Hopkins University in Baltimore is studying these highly focused predatory birds in an effort to understand the brain circuits that control attention. The team’s long-term goal is to figure out what goes wrong in the brains of people with attention […]

New Atlas: Tracking brain waves to decode mood could help fight depression

We all know that our moods can be mysterious, sometimes shifting seemingly at random and not necessarily dependent on what we’re doing. Unfortunately, even neuroscience in general is stumped by what’s going on in the brain when we feel joy or sadness. In an effort to peek inside our moody minds, a team of researchers […]

Futurity: Nasal spray could deliver cancer drugs right to the brain

A person’s brainstem controls some of the body’s most important functions, including heartbeat, respiration, blood pressure, and swallowing. Tumor growth in this part of the brain is therefore twice as devastating. Not only can such a growth disrupt vital functions, but operating in this area is so risky, many medical professionals refuse to consider it […]

Medical Xpress: Innovative technique reveals ‘core identities’ of brain cells

The human brain is made up of about 170 billion cells, each evolved to perform specific tasks, which raises a key question: What makes these cells different from one another? Most biologists are trying to answer this fundamental query by isolating cells one by one and taking their molecular fingerprints. By sequencing the RNA in […]

Newsweek: Scientists discover ‘bravery cell’s in the brain which could play a key role in anxiety

Scientists have identified cells in the brain which could influence how brave you are, according to a study published in the journal Nature Communications. People vary significantly when it comes to their willingness to try dangerous or exhilarating things, however, the biological mechanisms in the brain underpinning these tendencies have long remained a mystery. (September […]

Science Magazine: How does exercise keep your brain young?

Stay active; age gracefully. Behind this truism, there’s a pile of unanswered scientific questions. Researchers are still sorting out what it is about physical activity that seems to lower the risk of dementia later in life. Even more uncertain is whether the effects of exercise can alter the course of diseases that cause dementia—chief among […]

Medical News Today: Alzheimer’s: How does tau disrupt brain cells?

Scientists have found a previously unknown mechanism in which the protein tau, which is implicated in Alzheimer’s disease, damages brain cells by interfering with their internal communications.The discovery sheds new light on the origins of this most common cause of dementia, a hallmark of which is the buildup of tangled tau protein filaments in the […]
