How sound—but not touch—shapes rhythm in the brain
People are better at keeping the beat to sounds than to rhythmic vibrations
2025-10-13
(Press-News.org) How do people keep the beat to music? When people listen to songs, slow waves of activity in the brain correspond to the perceived beat so that they can tap their feet, nod their heads, or dance along. In a new JNeurosci paper, researchers led by Cédric Lenoir, from Université catholique de Louvain (UCLouvain), explored whether this ability is unique to hearing or whether it also happens when rhythm is delivered by touch.
The researchers recorded brain activity as study volunteers finger tapped to the beat of music delivered via sound or rhythmic vibration. With sound, the brain generated slow rhythmic fluctuations that matched the perceived beat, and people tapped along to the rhythm more steadily. However, with touch, the brain mainly tracked each burst of vibrations one by one, without creating the same beat-like fluctuations, and people were less precise in the way they synchronized with the rhythm.
Says Lenoir, “The ability to move in time with a beat is essential for human social interactions through music. Future research will help clarify whether long-term music practice can strengthen the brain’s ability to process rhythm through other senses, or whether sensory loss, such as hearing impairment, might allow the sense of touch to take over part of this function.”

Hypothermia can preserve neuron health following brain injury, but complications from external cooling make it less promising therapeutically. Recent evidence suggests that activating a specific neuron population triggers a reversible, hibernation-like hypothermic state without external cooling, but does this form of hypothermia still preserve neuron health? In a new JNeurosci paper, researchers led by Takeshi Sakurai at the University of Tsukuba explored this question using male mice.
The researchers found that triggering this specific hypothermic state in mice improved motor performance ...

Many advanced cancers develop resistance to treatment and become highly aggressive, often leaving patients with limited treatment options. In some cancers, including lung, pancreatic and prostate tumors, a key driver of treatment resistance and metastasis is a protein called integrin αvβ3, which is absent in normal tissues but enriched in aggressive tumors. Previous attempts to target αvβ3 with antibody therapies worked by activating a specific type of cell in the immune system called natural killer cells, but this approach ultimately failed to significantly improve patient survival in clinical trials, potentially because the tumors ...

University of California San Diego of Medicine researchers, in collaboration with the genetic testing company 23andMe, have identified regions of the human genome associated with cannabis use, uncovering new relationships with psychiatric, cognitive and physical health. The findings may inform the development of prevention and treatment strategies for cannabis use disorder. The study was published on October 13, 2025 in Molecular Psychiatry.
“Cannabis is widely used, but its long-term effects ...

About The Study: This analysis found that both low and high increases in social media use throughout early adolescence were significantly associated with lower performance in specific aspects of cognitive function, supporting a prior finding that greater screen time was negatively but weakly associated with adolescent cognitive performance.

A multi-center randomized controlled trial with critically ill adults aged 50 years and older admitted to intensive care units (ICUs) found that twice-daily slow-tempo music (60 to 80 beats per minute) did not shorten the duration of delirium or coma, or reduce delirium severity, pain or anxiety compared with a silence-track control.
While the trial did not mitigate delirium, it showed a trend to fewer days with delirium/coma among patients who received at least seven doses of slow-tempo music. There was also a trend toward fewer days of delirium/coma among patients ...

Sepsis, or infection causing life-threatening organ dysfunction, is a leading cause of death in children worldwide. In efforts to prevent this rare but critical condition, researchers developed and validated AI models that accurately identify children at high risk for sepsis within 48 hours, so that early preemptive care can be provided. These predictive models used routine electronic health record (EHR) data from the first four hours the child spent in the Emergency Department (ED), before organ dysfunction was present.
The multi-center study, led by Elizabeth Alpern, MD, MSCE, from Ann & Robert H. Lurie Children’s Hospital of Chicago, is the first to use ...

About The Study: In this cohort study, exposure to antenatal corticosteroids (ACS) was associated with increased risks of infections in full-term children until age 21. In preterm children born before 34 weeks’ gestation, no association between ACS and infections was found. To minimize the adverse effects of ACS treatment, more stringent criteria for ACS administration and better prediction tools for preterm birth are required.

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the production of blood stem cells.
Human blood stem cells, also known as hematopoietic stem cells, are immature cells that can develop into any type of blood cell, including red blood cells that carry oxygen and various types of white blood cells crucial to the immune system.
The embryo-like structures, which the scientists have named ‘hematoids’, are self-organising and start producing blood after around ...
