Rapid progress in brain organoid research prompts ethical debate

A new paper has tried to address the ethical debate surrounding human organoids by evaluating the potential risks of creating “humanized” animals

New study pinpoints emergence and progression of Alzheimer's plaque in the brain

Long before symptoms like memory loss even emerge, the underlying pathology of Alzheimer's disease, such as an accumulation of amyloid protein plaques, is well underway in the brain.

Brain stimulation increases functional connectivity of memory network

Magnetic stimulation of the posterior parietal cortex increases functional connectivity of a neural network implicated in memory, shows human research published in eNeuro.

Penn researchers propose ethical framework that defines brain organoid transplantation

As research involving the transplantation of human "mini-brains"--known as brain organoids--into animals to study disease continues to expand, so do the ethical debates around the practice.

The vulnerability to auditory hallucinations in schizophrenia may be established by infancy

Some people suffering from severe mental illness, particularly schizophrenia, hear "voices," known as auditory hallucinations.

Study shows how brake cell failure causes some types of seizure disorders

A study has revealed that brake cell failure causes some types of seizure disorders.

Study analyzes etiology of substance use disorders and their associations with family systems

It's no secret that substance use disorders (SUDs) can negatively impact the individual struggling, even putting their life in jeopardy.

Researchers offer new evidence for the mechanisms underlying consciousness

No-one knows what connects awareness - the state of consciousness - with its contents, i.e. thoughts and experiences. Now researchers propose an elegant solution: a literal, structural connection.

Cellular aging associated with structural changes in the brain

Telomeres are protective caps at the ends of chromosomes that become shorter with each cell division. If they become so short that the genes they protect could be damaged, the cell stops dividing and renewing.

Intensive physical training can harm brain capacity, shows study

In top athletes, excess physical activity can be harmful, as cases of 'overtraining syndrome' suggest. It is associated with major fatigue and reduced athletic performances.

Does the brain thin as children grow?

Neuroscientists have long held that the brains of children thin down over time. However, this was on the basis of older imaging techniques. Now, using cutting-edge technology in the form of quantitative magnetic resonance imaging (qMRI), a team of researchers has found that the apparent thinning is due in part to myelin formation around the cortical nerve fibers. These very interesting findings, published in the journal PNAS on September 23, 2019, will drive further research on the link between cortical function and structure.

Physiologists, researchers to discuss factors underlying cardiovascular disease at APS conference

International physiologists and researchers studying the kidney, high blood pressure and related medical conditions will convene next week at the American Physiological Society (APS) Aldosterone and ENaC in Health and Disease: The Kidney and Beyond Conference in Estes Park, Colo.

AGS patients more likely to suffer from sexual dysfunction, shows study

AdrenoGenital Syndrome (AGS) encompasses a group of inherited metabolic disorders caused by a disruption in steroid hormone production in the adrenal cortex.

Excessive athletic training can make the brain tired, study reveals

You'd expect excessive athletic training to make the body tired, but can it make the brain tired too? A new study reported in the journal Current Biology on September 26 suggests that the answer is "yes."

Thinning of human brain during childhood linked with myelination

Using state-of-the-art brain imaging techniques, Vaidehi Natu at Stanford University in California, along with her colleagues from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, provide striking results that suggest the brains of children likely do not thin as much as expected.

Research suggests new strategy to prevent performance degradation caused by anxiety

Researchers in the Center for Information and Neural Networks, the National Institute of Information and Communications Technology, Japan and the Centre national de la recherché scientifique, France used fMRI to discover a new neural mechanism involving the dorsal anterior cingulate cortex to explain how anxiety deteriorates physical performance.

Scientists discover how neural circuits play critical role in learning and memory

A University of California, Irvine-led team of scientists has discovered how newly identified neural circuits in the brain's hippocampal formation play a critical role in object-location learning and memory.

Study sheds light on mechanisms behind correlated electrical activity in neurons

"Like a book in which the single pages are not all different but carry small portions of common text, or like a group of people who whistle a very similar tune": this is how our brain cells work, say scientists. It is the phenomenon of "co-relation", in which individual neurons do not always act as independent units in receiving and transmitting information but as a group of individuals with similar and simultaneous actions.

Neuroscientists analyze why the brain is disturbed by harsh sounds

Why do the harsh sounds emitted by alarms or human shrieks grab our attention? What is going on in the brain when it detects these frequencies?

Daniel Weinberger wins NAM's Sarnat Prize for schizophrenia research

The National Academy of Medicine today announced Daniel Weinberger is the recipient of the 2019 Rhoda and Bernard Sarnat International Prize in Mental Health, for his fundamental role in elucidating the biological origins and genetic expressions of schizophrenia, and for transforming how clinicians, researchers, and the public understand mental illness.
