Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.

Small group of airway neurons plays a key role in alerting the brain about infection

A new study led by researchers at Harvard Medical School illuminates how the brain becomes aware that there is an infection in the body.

New model, C. elegans, helps pursue research on Parkinson's disease

A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.

Scientists discover two ways to preserve diseased upper motor neurons in ALS

Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.

Study provides new insight into the brain circuits involved in opioid addiction

The ongoing opioid epidemic continues to take a heavy toll on American communities, with more than 80,000 opioid-related deaths reported in 2021, according to the National Institutes of Health.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.

DZNE scientists discover major role of centrosome in neuronal migration

Researchers from the DZNE have solved an important puzzle in neurobiology: the wiring and the movement of nerve cells are interwoven, but separately controlled.

Novel mechanism of DNA repair occurring in neurons uncovered

"Use it or lose it" goes the adage, applied liberally to everything from our muscles to our minds, especially as we age.

IGSF3-mediated potassium dysregulation drives glioma-related epilepsy

Glioma is one of the most aggressive malignant primary brain tumors. A common feature of glioma is the presence of localized, intermittent seizures referred to as glioma-related epilepsy, which is known to promote tumor growth. However, the mechanism involved at the molecular level is still not clear.

Inhibiting astrocyte hyperactivity can reverse cognitive deficits associated with social deprivation

Here is an important reason to stay in touch with friends and family: social isolation causes memory and learning deficits and other behavioral changes.

Pancreatic islet microexons play key role in islet function and glucose homeostasis

When cells copy DNA to produce RNA transcripts, they include only some chunks of genetic material known as exons and throw out the rest.

Large-scale differentiation of iPSC-derived motor neurons from ALS patients

A new Cedars-Sinai study in collaboration with the University of California, Irvine (UCI) and the Answer ALS consortium has examined the expression of thousands of genes in stem cell generated motor neurons that are known to die in patients with amyotrophic lateral sclerosis, a fatal neurological disorder known as ALS or Lou Gehrig's disease.

Potential approach for mitigating ALS pathogenesis

Every year, 5,000 people in the United States are diagnosed with ALS, an incurable neurodegenerative disease that will destroy them within two to five years.

Discovery of a new cellular element crucial to sense of smell

Researchers at Umeå University have found an organelle, a previously unidentified cellular component, inside the neurons that are responsible for the ability to smell. The finding might have repercussions for future studies on COVID-19 symptoms like impaired smell sense.

Scientist honored for his contribution on ALS research

The Drs Ayeez and Shelena Lalji & Family ALS Endowed Award for Innovative Healing was given to Clive Svendsen, PhD, a pioneer in regenerative medicine, for his significant contributions to the field of amyotrophic lateral sclerosis (AL) at Massachusetts General Hospital’s Sean M. Healey & AMG Center for ALS.

Highlighting the potential of new techniques to study mental disorders

Researchers investigating the fundamental brain mechanics of autism spectrum disorder have discovered that a gene mutation known to be connected with the illness causes considerably more overstimulation of brain cells than in neuronal cells without the mutation.

“Junk” DNA could provide access to innovative treatments for neurological conditions

The breakthrough study from the University of Sheffield’s Neuroscience Institute and Healthy Lifespan Institute offers critical new insights into the so-called junk DNA, or DNA that was previously believed to be unimportant to the coding of the genome, and how it affects neurological disorders like Motor Neuron Disease (MND) and Alzheimer’s.
