Scientists have long puzzled about a critical way that cells communicate with one another, but Rutgers researchers have used a simple roundworm to solve the mystery.
Florida State University researchers have identified a new pathway in the brain that plays an important role in our response to fear. Scientists have long considered the amygdala, an almond-shaped structure in the center of the brain, to be the “center of fear” and believed it to be largely responsible for how an individual responds to frightening circumstances or perceives threats.
Treatment for glioma has long relied on MRI imaging to track tumor markers and treatment response. But findings from a team at the University of Michigan Rogel Cancer Center, led by Carl Koschmann, M.D., pediatric neuro-oncologist at University of Michigan Health C.S. Mott Children’s Hospital and researcher with the Chad Carr Pediatric Brain Tumor Center, suggest a new method could provide additional data about tumor markers before changes appear on an MRI, indicating possible strategies to help clinicians address this aggressive form of cancer. The recent study appeared in Neuro-Oncology.
Anti-seizure medications are not a cure, and about 30% of people with epilepsy don't respond to them. How are new medications discovered, and what's on the horizon?
Researchers describe a mechanism in mice that underlies local dopamine release in the brain
The researchers set out to see if there had been an increase in the numbers of older people who were reporting their first concerns about memory loss or cognitive decline to their doctor and what their chances of developing dementia were after consultation.
Mayo Clinic researchers have validated a new antibody test to diagnose multiple sclerosis (MS), a potentially disabling disease of the brain and spinal cord. Nearly 1 million people in the U.S. are affected by MS, according to the National Multiple Sclerosis Society.
Professor Emeritus Moussa Youdim is the recipient of the 2022 Israel Prize for Life Sciences. He is co-developer of the Parkinson's disease drug Azilect (Rasagiline), and was selected for the Israel Prize "for his pioneering, groundbreaking scientific achievements in the field of neuropharmacology."
Children of mothers with clinical depression are at three times greater risk to develop depression themselves than are their low-risk peers.
Parkinsonism is a term for a group of neurological conditions that cause movement problems including tremors, slowed movement and stiffness, with Parkinson’s disease being one of the better knowns causes. A new study suggests that older people taking statin drugs have a lower chance of developing parkinsonism later compared to people who were not taking statins. The research is published in the March 23, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology. Statins are drugs used to lower cholesterol in the blood and protect against atherosclerosis, a buildup of plaque in the arteries that can lead to hardening of the arteries, heart attack and stroke.
The molecular processes caused by a TREM2 (Triggering Receptor Expressed on Myeloid Cells 2) gene mutation in the brain’s microglia immune cells can increase the risk of Alzheimer’s disease, according to a recent study led by researchers at the University of California, Irvine. While many immune cell genes have been associated with Alzheimer’s, the odds are increased two to three times by mutations in TREM2. However, the processes by which these mutations change the function of microglia cells have not been identified until now.
The stress hormone cortisol reduces altruistic behavior and alters activity in brain regions linked to social decision making — but only in people who are better at imagining others’ mental states, according to new research published in JNeurosci.
“We don’t know yet if there’s a cumulative, long-term effect to these small daily fluctuations in cognition,” Zlatar said. “That’s something we plan to study next – to see if performing physical activity at different intensities over time, in unsupervised settings, can produce long-term improvements in brain health and sustained behavior change.”
A team led by engineers at the University of California San Diego has developed a device that is a first step to enabling noninvasive, ultrasound-based therapies for the brain. For example, ultrasound waves are currently being used in clinical trials to treat epilepsy.
A new study from an international team of researchers — including two from Binghamton University — demonstrates that social media could be used to detect behaviors preceding sudden unexpected death in epilepsy (SUDEP), the leading cause of death in people with uncontrolled epileptic seizures.
These are promising findings adding to a growing body of evidence showing that virtual reality can be used to measure cognition and related everyday functioning effectively and accurately. The next steps will be to confirm these results and expand research into conditions characterised by cognitive complaints and functional difficulties such as psychosis and Alzheimer’s Disease.
The use of medications and exercise is more beneficial in preventing a second stroke in people with intracranial atherosclerosis than placing a stent in the blood vessel, according to a new practice advisory issued by the American Academy of Neurology (AAN). The practice advisory is published in the March 21, 2022, online issue of Neurology®, the medical journal of the AAN, and is endorsed by the American Heart Association/American Stroke Association, Neurocritical Care Society and Society of Vascular and Interventional Neurology.
Researchers at Palo Alto University’s (PAU) Behavioral Research and Assessment in Neuropsychology (BRAIN) Lab, are compiling data to help families and sports organizations assess when it is safe for student-athletes to return to play after a concussion. As part of Brain Injury Awareness Month, The BRAIN Lab team and Rayna Hirst, PhD, who directs the University’s neuropsychology program, offer several important tips for parents of student athletes.
Scientists at La Jolla Institute for Immunology (LJI) have found that people with Parkinson's disease have a clear "genetic signature" of the disease in their memory T cells. The scientists hope that targeting these genes may open the door to new Parkinson's treatments and diagnostics.

There’s nothing like a cuppa to give your morning a boost. Researchers report the first use of waste coffee grounds as electrode coatings for sensitive neurochemistry measurements, which could help scientists get a better handle on brain activity. They will present their results at ACS Spring 2022.
