Improving Alzheimer’s disease imaging — with fluorescent sensors
Now, researchers in ACS Central Science demonstrate a way of packaging fluorescent sensors for easy passage across the blood-brain barrier in mice, allowing for improved brain imaging. With further development, the technology could help advance Alzheimer’s disease diagnosis and treatment.
Innovative fMRI Study Finds Larger Warning Labels Including Pictures Linked to Lower Desire to Consume Alcohol Products
Young adult men who viewed alcohol warning labels experienced a lower activation of the reward circuits in their brains when the warnings were larger and involved pictures, compared to more familiar small-text warnings, in a first-of-its-type study. The findings could inform more effective messaging on alcohol-containing beverages and advertisements. Despite recommendations from the World Health Organization and European Commission that warning labels be included on alcoholic products, few countries have implemented alcohol warning policies comparable to their approach to tobacco. Alcohol warnings are typically small, text-only messages. Research has been equivocal about their impact on drinking and whether incorporating pictures would increase their effectiveness, in part because most studies have relied on participants’ self-reported reactions. Functional magnetic resonance imaging (fMRI) has demonstrated variations in brain activation in response to varying types of tobacco warnings

Findings may help inform the development of intervention and prevention strategies
Concurrent use of alcohol and cannabis leads to higher levels of drinking in the longer term
Co-existing use of alcohol and cannabis can lead to negative outcomes such as the development of a substance-use disorder, poor academic and occupational performance, and psychiatric disorders when compared to use of either drug alone. New research that examines simultaneous alcohol/cannabis use has found higher levels of drinking after 18 months. These results and others will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.
Pioneering MRI imaging method captures brain glucose metabolism without the need for administration of radioactive substances
A research team has developed a completely new magnetic resonance imaging (MRI) approach. Using a harmless glucose solution, the procedure generates reliable results and – in principle – can be used with all common MRI scanners.
Lonely People’s Divergent Thought Processes May Contribute to Feeling “Alone in a Crowded Room”
Lonely individuals’ neural responses differ from those of other people, suggesting that seeing the world differently may be a risk factor for loneliness regardless of friendships.

From medical training during a civil war to starting Kentucky’s first epilepsy fellowship program, Dr. Meriem Bensalem-Owen talks with Sharp Waves about her career journey.
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.
Neuroimaging Study Reveals Functional and Structural Brain Abnormalities in People with Post-Treatment Lyme Disease
In a study using specialized imaging techniques, Johns Hopkins Medicine researchers report distinctive changes in the “white matter” and other brain tissue physiology of those with post-treatment Lyme disease, a condition affecting 10% to 20% of the nearly half a million Americans who contract Lyme disease annually.
Human Cocaine and Heroin Addiction Is Found Tied to Impairments in Specific Brain Circuit Initially Implicated in Animals
Study results suggest the pre-frontal cortex-habenula circuit is potentially amenable for targeted interventions and prevention.
Steroid meds linked to structural and volume changes in brain white and grey matter
The use of prescribed steroids, including in inhalers, is linked to changes in the structure and volume of white and grey matter in the brain, suggests the findings of the largest study of its kind, published in the open access journal BMJ Open.
Researchers of the Human Brain Project identify seven new areas in the insular cortex
All newly detected areas are now available as 3D probability maps in the Julich Brain Atlas, and can be openly accessed via the HBP’s EBRAINS infrastructure.
Using new technique, researchers make surprising discoveries about how flies’ brains respond to tastes
Taste matters to fruit flies, just as it does to humans: like people, the flies tend to seek out and consume sweet-tasting foods and reject foods that taste bitter.
Sentences Have Their Own Timing in the Brain
Our brain links incoming speech sounds to knowledge of grammar, which is abstract in nature.
An Appetite Map in the Brain
Let’s face it. As enticing as the idea of starting lunch with a chocolate cake might be, few would actually make that choice when it comes down to it.

Artificial Intelligence Reveals Links Between Individual Differences in Brain Anatomy and Differences in Autism Spectrum Disorder Symptoms
Differences in behavior among people with Autism Spectrum Disorder (ASD) are closely related to differences in neuroanatomy – the shape of a brain – a team of Boston College neuroscientists report today in the journal Science. This discovery could help to understand the causes of ASD, and to develop personalized interventions.

New advances in brain region targeting may support future research in treating visual hallucinations in psychiatric patients
A literature review in Harvard Review of Psychiatry indicates that, while transcranial electrical stimulation (tES) has rarely been used in treating visual hallucinations (VH) among patients with psychiatric disorders, recent advances in neuroimaging technology show promise in helping tES to more effectively treat VH in psychiatric disorders where VH are a core symptom. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Neurological Complications of COVID-19 in Children: Rare, but Patterns Emerge
While neurological complications of COVID-19 in children are rare, in contrast to adults, an international expert review of positive neuroimaging findings in children with acute and post-infectious COVID-19 found that the most common abnormalities resembled immune-mediated patterns of disease involving the brain, spine, and nerves. Strokes, which are more commonly reported in adults with COVID-19, were much less frequently encountered in children. The study of 38 children, published in the journal Lancet, was the largest to date of central nervous system imaging manifestations of COVID-19 in children.

Brain model offers new insights into damage caused by stroke and other injuries
A University at Buffalo neuroimaging researcher has developed a computer model of the human brain that more realistically simulates actual patterns of brain impairment than existing methods. The novel advancement represents the union of two established approaches to create a digital simulation environment that could help stroke victims and patients with other brain injuries by serving as a testing ground for hypotheses about specific neurological damage.
