Summary: For the first time, researchers can record the complete electrical activity across an entire lab-grown human neural organoid. These “mini-brains” are powerful models for studying development and disease, but until now existing sensors could only sample a small portion of their activity because they were flat and rigid. A new study describes a soft, … Read more

Summary: Combining non-invasive brain stimulation with a person’s favorite music from the past may help activate long-held memories and improve mood for older adults with mild cognitive impairment (MCI), according to a new study led by researchers at Baycrest. Source: Baycrest. Baycrest begins the first clinical study pairing personalized music therapy with brain stimulation to … Read more

Summary: A new twin study reveals how genetics shape grey matter regions in the ageing human brain. Source: University of New South Wales UNSW Australia researchers have completed a landmark twin study examining genetic influences on key brain structures in people aged 65 and older. An important international study of healthy older twins has provided … Read more

Summary: Just ten minutes of moderate running increases activation in both sides of the prefrontal cortex, improving mood and executive functioning. Source: University of Tsukuba A brief bout of moderate running can meaningfully boost mental health. Researchers at the University of Tsukuba report that a 10-minute session of moderate-intensity running raises local blood flow across … Read more

Summary: When people listen to music, neural activity in the frontal lobe follows activity in the temporal lobe; during musical recall, the frontal lobe leads the temporal lobe. These results reveal bottom-up and top-down processing in the cortex during listening and remembering, shedding light on how the human brain represents and tracks familiar music. Source: … Read more

Weight Loss from Midlife to Late Life Associated with Higher Risk of Mild Cognitive Impairment Increasing weight loss per decade between midlife and late life was associated with a greater risk of developing mild cognitive impairment (MCI), according to findings published in JAMA Neurology. Mild cognitive impairment is an early, prodromal stage of dementia. Each … Read more

Summary: Researchers at CNB-CSIC have developed a COVID-19 vaccine candidate that appears to prevent SARS-CoV-2 from infecting the brain and blocks the neurological damage associated with the virus in a susceptible mouse model. Source: University of Seville While COVID-19 primarily affects the respiratory system, a significant number of patients experience neurological symptoms, including loss of … Read more

Summary: Researchers are reassessing the therapeutic potential of psychedelics as an antidepressant option for people with depression. Source: Virginia Commonwealth University For almost five decades, research on psychedelics was largely sidelined. Now an increasing number of scientists, including Javier González-Maeso, Ph.D., and Mario de la Fuente Revenga, Ph.D., in the Department of Physiology and Biophysics … Read more

Have you ever wondered why the human brain evolved the way it did? Researchers led by Northeastern physicist Dmitri Krioukov propose an intriguing answer: the brain’s wiring has evolved to speed information transfer between regions, allowing us to respond quickly and operate at high efficiency. Their analysis suggests the brain’s structural network is nearly optimal … Read more

Summary: Guided by Moral Foundations Theory (MFT), researchers investigated the neural basis of moral judgment. They found a common network of brain regions engaged when people judge moral violations, but also identified distinct activity patterns for different moral categories. These results support a pluralistic view of morality and show that political ideology influences how moral … Read more
