Brain protein linked to seizures, abnormal social behaviors

by Iqbal Pittalwala, University of California – Riverside Confocal image of a mouse brain tissue shows the astrocytes (red) and neurons (green). Credit: Ethell lab, UC Riverside. A team led by a biomedical scientist at the University of California, Riverside has found a new mechanism responsible for the abnormal development of neuronal connections in the...

Investigational drug stops toxic proteins tied to neurodegenerative diseases

by Melissa Moody, Perelman School of Medicine at the University of Pennsylvania An investigational drug that targets an instigator of the TDP-43 protein, a well-known hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), may reduce the protein’s buildup and neurological decline associated with these disorders, suggests a pre-clinical study from researchers at Penn...

New form of brain analysis engages whole brain for the first time

by Duke University A new method of brain imaging analysis offers the potential to greatly improve the effectiveness of noninvasive brain stimulation treatment for Alzheimer’s, obsessive compulsive disorder, depression, and other conditions. Duke researchers developed the new method, which for the first time analyzed the whole brain network rather than a single region of the...

Newly discovered ‘support system’ for axons suggests a novel therapeutic target for neurodegenerative diseases

by Ellen Goldbaum, University at Buffalo This image shows axons in vitro 24 hours after injury. The presence of Schwann cells (nuclei in cyan) helped maintain the integrity of axons (in magenta and yellow). Credit: Elisabetta Babetto, HJKRI Axons are long, finger-like projections of neurons that transmit critical signals throughout the nervous system. But because...

Research explores how the brain functions

What does each part of the brain do and why? Can we communicate with a patient in a coma? How does continual cell phone screen-time affect us? These are the kind of questions that Brian Arwari ponders every day. A cognitive psychologist by training, he leads the neurocognitive lab in the Department of Kinesiology and...

Hallucinations: What explains these tricks of the mind?

Hallucinations are sensory perceptions that appear in the absence of stimuli. Although they are often associated with illnesses such as schizophrenia, these phenomena can occur in the absence of mental ill health. But what explains these uncanny occurrences? Not all hallucinations occur due to psychotic disorders or psychedelic drugs. There are many types of hallucinations....

New stem cell model to study how cancer arises

by Tabea Kemna, Karolinska Institutet In an interdisciplinary study combining stem cell biology and tumor biology, researchers from Karolinska Institutet (as well as Uppsala and Lund University, together with researchers in Canada, Germany and France), have succeeded in creating a new type of stem cell model for studies on cancer of the brain. The study...

Transcranial stimulation to prevent fear memories from returning

by University of Bologna research group from the University of Bologna has succeeded in modifying the negative effect of a returning memory that triggers fear, and developed a new non-invasive experimental protocol. The result of this study, published in the journal Current Biology, is an innovative protocol that combines fear conditioning—a stimulus associated with something...
