As a developmental neurobiologist at Harvard University, Paola Arlotta spends most of her time thinking about how the brain develops, how it functions, and what goes wrong in the context of neurological disease. Using human brain organoids as a model for brain development and disease research has been a game changer, providing Arlotta a novel view into brain pathologies that form in utero.

Your brain in the zone: A new neuroimaging study reveals how the brain achieves a creative flow state

Posted by in categories: biotech/medical, business, education, neuroscience

The University of Chicago Medicine is among the first 30 institutions in the country to offer tumor-infiltrating lymphocyte (TIL) therapy for advanced melanoma, immediately activating as an authorized treatment center after federal regulators approved the treatment on February 16, 2024.


Effortless, enjoyable productivity is a state of consciousness prized and sought after by people in business, the arts, research, education and anyone else who wants to produce a stream of creative ideas and products. That’s the flow, or the sense of being “in the zone.” A new neuroimaging study from Drexel University’s Creativity Research Lab is the first to reveal how the brain gets to the creative flow state.

The study is published in the journal Neuropsychologia.

Exposure to different kinds of music influences how the brain interprets rhythm

Posted by in categories: media & arts, neuroscience

When listening to music, the human brain appears to be biased toward hearing and producing rhythms composed of simple integer ratios—for example, a series of four beats separated by equal time intervals (forming a 1:1:1 ratio).

However, the favored ratios can vary greatly between different societies, according to a large-scale study led by researchers at MIT and the Max Planck Institute for Empirical Aesthetics and carried out in 15 countries. The study included 39 groups of participants, many of whom came from societies whose traditional contains distinctive patterns of rhythm not found in Western music.

“Our study provides the clearest evidence yet for some degree of universality in music perception and cognition, in the sense that every single group of participants that was tested exhibits biases for integer ratios. It also provides a glimpse of the variation that can occur across cultures, which can be quite substantial,” says Nori Jacoby, the study’s lead author and a former MIT postdoc, who is now a research group leader at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany.

Major discovery in the genetics of Down syndrome

Posted by in categories: biological, genetics, neuroscience

Researchers at CHU Sainte-Justine and Université de Montréal have discovered a new mechanism involved in the expression of Down syndrome, one of the main causes of intellectual disability and congenital heart defects in children. The study’s findings were published today in Current Biology.

Down (SD), also called trisomy 21 syndrome, is a genetic condition that affects approximately one in every 800 children born in Canada. In these individuals, many genes are expressed abnormally at the same time, making it difficult to determine which contribute to which differences.

Professor Jannic Boehm’s research team focused on RCAN1, a gene that is overexpressed in the brains of fetuses with Down syndrome. The team’s work provides insights into how the gene influences the way the condition manifests itself.

Professor studies link between adversity, psychiatric and cognitive decline

Posted by in categories: biotech/medical, health, neuroscience, policy

Saint Louis University associate professor of health management and policy in the College for Public Health and Social Justice, SangNam Ahn, Ph.D., recently published a paper in Journal of Clinical Psychology that examines the relationship between childhood adversity, and psychiatric decline as well as adult adversity and psychiatric and cognitive decline.

His team discovered that just one instance of adversity in childhood can increase cases of mental illness later in life, and adverse events in adults can lead to a greater chance of both mental illness and cognitive decline later in life.

“Life is very complicated, very dynamic,” Ahn said. “I really wanted to highlight the importance of looking into the lasting health effect of adversity, not only childhood but also adulthood adversity on health outcomes, especially and psychiatric and cognitive health. There have been other studies before, but this is one of the first that looks into these issues comprehensively.”

Scientists identify new ‘regulatory’ function of learning and memory gene common to all mammalian brain cells

Posted by in categories: biotech/medical, genetics, neuroscience

Johns Hopkins Medicine neuroscientists say they have found a new function for the SYNGAP1 gene, a DNA sequence that controls memory and learning in mammals, including mice and humans.

The finding, published in Science, may affect the development of therapies designed for children with SYNGAP1 mutations, who have a range of neurodevelopmental disorders marked by intellectual disability, autistic-like behaviors, and epilepsy.

In general, SYNGAP1, as well as other genes, control learning and memory by making proteins that regulate the strength of synapses—the connections between brain cells.

Learning and memory problems in Down syndrome linked to alterations in genome’s ‘dark matter’

Posted by in categories: biotech/medical, genetics, neuroscience

Researchers at the Centre for Genomic Regulation (CRG) have found that the Snhg11 gene is critical for the function and formation of neurons in the hippocampus. Experiments with mice and human tissues revealed that the gene is less active in brains with Down syndrome, potentially contributing to the memory deficits observed in people living with the condition. The findings are published in the journal Molecular Psychiatry.

Traditionally, much of the focus in genomics has been on , which in humans constitute around just 2% of the entire genome. The rest is “dark matter,” including vast stretches of non-coding DNA sequences that do not produce proteins but are increasingly recognized for their roles in regulating gene activity, influencing genetic stability, and contributing to complex traits and diseases.

Snhg11 is one gene found in the dark matter. It is a long non-coding RNA, a special type of RNA molecule that is transcribed from DNA but does not encode for a protein. Non-coding RNAs are important regulators of normal biological processes, and their abnormal expression has been previously linked to the development of human diseases, such as cancer. The study is the first evidence that a non-coding RNA plays a critical role in the pathogenesis of Down syndrome.
